uh_huh it's so the this presentation he is uh the presentation c. v. now to the presentation
00:00:08
in a your g. o. six but a shop to of course i'm uh i'm
00:00:13
to propose offices vector this uh around the word use
00:00:19
entity cover using announced plans of a us works
00:00:22
however until now this month jail materials and go
00:00:25
to some difficulties for all the application
00:00:29
i mean about the we we so she's a carry out about the damage of a jew synthetics
00:00:36
uh this is elapsed time but it's always difficult to see rachel combination
00:00:41
of a solicitation or as a existing in in the field
00:00:46
yeah yeah for some the question a pending and uh first one is due
00:00:52
to joe's athletics fulfils a function over a long period of time
00:00:57
a second is uh as the concept as uh as as you design
00:01:03
guidelines of course well couldn't you just want it looks good i
00:01:08
uh so lessons can be learned from casey stories
00:01:13
and the quarter was feed them as a and myself
00:01:18
uh up recently involving a wider problem of a
00:01:23
visit of side and that if possible investigation
00:01:27
ways of format design no n. contact the easy are not the type and i'm like that support
00:01:34
uh as additional interest of this presentation in our
00:01:38
opinion is a link and to the fact
00:01:41
so that's the news innovation of engine is is uh
00:01:45
and now where about this form applications outrageous antics
00:01:51
and for convenience the reasons uh the presence survey is limited to to finance
00:01:56
uh until now uh fifteen or structures wheeze adjusts entity x. where it
00:02:02
well this week with an a a five hour presented today and they're all of cause this
00:02:09
is a privilege of uh we sasha still a a a lighter an active huh
00:02:16
uh like us to uh have for a wide doing to our two
00:02:20
five begets the because you hold for just sent it takes doctor
00:02:26
the first uh uh a case easy so we ease a a dime
00:02:30
this is a a down uh in the south of france in a a marvel on
00:02:36
an a format nineteen uh seventy six
00:02:41
and uh so is used on use um a six meter a fruit and uh as a uh
00:02:48
a structure included a a woven jew text by these
00:02:56
this is a a view of uh
00:03:00
that is the the i'm just after construction as a design he's uh specifically
00:03:06
or regional now with a steep slopes uh at the downstream side
00:03:14
and this is the view of the model the um uh even uh uh uh uh the rights and that
00:03:21
in in ninety six and some then match on
00:03:24
the facing a usable but in fact that
00:03:28
i in uh our opinion use a possibility to do to a new or an
00:03:34
uh in a two thousand and fourteen apparently no evolution of the damage
00:03:40
a happy and despite the uh like or for maintenance of
00:03:47
the structure so sir construct your user retaining wall
00:03:52
in a pop put or close to uh to him
00:03:57
uh i just sort your is a a a look at it in a ski resort
00:04:03
uh and so and the specificity of
00:04:08
a disease a structure is firstly
00:04:11
um as the eight of course uh and also
00:04:16
um as a sickness of every layer of uh
00:04:20
uh uh sorry between two uh jews entity
00:04:25
is one point twenty a meter which is totally uncommon uh
00:04:31
uh uh it was not that he was a
00:04:33
demonstrated that is not in safe but that is a
00:04:37
it's never use the in a stand out
00:04:40
a construction and as a second uh specificity is
00:04:45
uh the facing the facing is and protected
00:04:49
uh against u. v. radiation and uh it is
00:04:53
interesting to re evaluate the then edge
00:04:58
uh after more than two the cats uh you to to a certain group
00:05:06
this is the um and the structure just after construction
00:05:11
and the joe textile he's a polyester who've run
00:05:17
and as you see says the construction construction technique was
00:05:21
who would as usual at this time yeah
00:05:25
he sees the facing in uh in nineteen uh ninety one
00:05:32
and uh yeah this is the view in a it winter
00:05:39
and that i finally redesign joe tex style was not supposed to be exposed
00:05:46
tucson edition nevertheless and tina to us i was on a n. nine
00:05:53
so uh twenty seven years after construction no
00:05:57
damage of the facing as being that
00:06:00
is this is uh the foster the flaws damage or on the facing
00:06:07
and several or local collapse of the jews textile
00:06:11
uh at the bottom ah also appearing after
00:06:15
a twenty a seven uh years
00:06:20
so this plight as a local disturbance of
00:06:23
uh the facing is important to notice
00:06:27
there's a structurally stable and no said then meant to the sub server
00:06:32
in uh the upper part on the pavement for example
00:06:38
so the conclusion for these away turning stricter is not on the on the formation
00:06:44
wasn't that is on the quest of the war despite as report on selected
00:06:49
spacing between the layers or choose text i'd just
00:06:53
strains of the facing to climates twice
00:06:56
is is not well see more than twenty five euro else only in uh
00:07:02
two thousand and nine as the first two years of joe
00:07:06
tex light appeared on the faces of the whitening structure
00:07:10
forcing the oh no to cover all it despite no problem of overall stability
00:07:17
uh first case d. r. so crazy story uh letting you structure
00:07:22
with additional facing supporting the inflatable from work she's
00:07:28
was uh and wishing under a process
00:07:31
and uh is the main feature of this uh is always you know joe technology
00:07:37
why has a a total independence of the available so the structure with the protective
00:07:43
but i stick a facing this is uh the facing excuse me please
00:07:50
the facing and uh this is the uh the call for the um inflatable go for
00:07:58
that which is possible to you was that
00:08:00
uh in connection with the concrete facing
00:08:06
so this is a technique was proposed by the l. c. p. c. and the so side the a button
00:08:15
uh and evolution of us use a a a a a display uh on the slide
00:08:23
uh the the fix we see the difference which support temple
00:08:28
only doing costly shuns the form well who would be
00:08:32
also fulfilled by admit that it stays on court
00:08:37
at the best of a complete show foundation
00:08:41
and uh this is uh the evolution of the splitter uh
00:08:47
for a very highly selective twenty one meter high
00:08:52
so we have four seven of uh uh the structure uh is corresponding to the
00:08:59
i'd the studio in the world are on
00:09:03
the title of construction twenty one meta
00:09:07
and that different ah the joy textile where you also depending
00:09:12
of the i of course of a wonderful fire
00:09:19
the the construction of the structure
00:09:23
which is a complete facing and then
00:09:27
yeah yeah this is a a a view also money delaying yeah
00:09:32
uh i'll just look to to follow the deformation during the construction
00:09:39
anyway this is a a few others to do it in a two star was on an a sixteen
00:09:46
this is a feed the mass of the state and uh and this
00:09:51
is a highway on the top of the slip through them
00:09:56
huh
00:09:58
and that is this is a a view of the sort through a a twenty
00:10:09
what
00:10:14
four of action
00:10:18
okay it's a
00:10:20
uh yeah uh so if this is a a view of uh uh as it was just like
00:10:25
you always uh the joe tex style ah which is protected by is the concrete face
00:10:33
and that it is interesting to to compare yeah and as the design
00:10:38
it or the the only not design it either in uh
00:10:42
now this we we subways and design it to
00:10:45
your cord and uh uh the same calculation
00:10:49
method is used in the two case with uh some the same critical see blind
00:10:55
and um uh considering the two uh uh design it uh that
00:11:01
and the value of the design just wang's is uh in a night this we
00:11:06
one hand whether an uh twenty five q. don't you done for the bottom layer
00:11:10
of uh joe text item and that in a in a two thousand sixteen
00:11:15
ninety nine for the bottom they considering the partial facto at this time and
00:11:22
for that would be mad at least ranks in then i'd this we it was a four
00:11:27
and read and assaulted in and uh even uh it
00:11:31
too so then sixteen three hundred and forty two
00:11:36
let's remind that the ultimate strengths of the selected joe sent to take
00:11:40
at the bottom of the war was uh uh a known who've been with
00:11:46
a wheel false man uh around the four hundred couldn't you don't permit
00:11:53
uh finally the conclusion for this example the example presented via the most that that
00:11:58
joe technology a load to control the deformation of highlighting straight to right
00:12:04
uh twenty three years after the structure is a stable or
00:12:08
uh yeah i there's in the present case before
00:12:11
now design was more conservative than the present your committed
00:12:16
i thought and that is a construction pauses
00:12:19
a present it uh uh is not use a
00:12:23
uh now uh despite its technical interests
00:12:28
uh of fools example adjusts entity can force men over cavities
00:12:35
uh as this easy in the region of uh
00:12:39
a mass say use some so false and uh the the close to the
00:12:45
a close to those sums of the city and then
00:12:48
uh in this part the the sorry is uh
00:12:52
uh uh in a it is a cast a a cast
00:12:59
a room vision and and that for this reason
00:13:02
there is the possibility of suited as a a a and those the pavement and there
00:13:10
this is a a constriction of full or the in
00:13:15
this part of the city of a must say
00:13:19
and uh this is uh the joe sent it eek so on coverage of the juice entity it yeah
00:13:26
and there is this is the uh the view of the studio in a two thousand and a sixty
00:13:34
um uh does basically see he was uh the use of a joe's text
00:13:40
tied ways that tool model is the first pass is very stiff
00:13:46
uh you know the shoes sustain or a maximum settlement of ten
00:13:52
sentiment there and they're an x. r. load of uh
00:13:55
a thirty five clear node and and uh the second part is in combination
00:14:02
ways and uh the value of uh uh the maximum must ranks and
00:14:08
you know they ought to obtain nevada in case of accident load
00:14:13
of a one hundred and so thick you don't bend
00:14:17
um this is the second part of the the structure of a
00:14:22
joe tex style which is acting in this case and
00:14:26
so and the only thing that would be more there is joe tex i probably
00:14:32
haven't either a breast polyester yeah joe tex that was you was an
00:14:37
once efficient and uh it's also possible to compare
00:14:43
the a calculation in the two case
00:14:46
and in the two k. finally we we'll say our phones the only he nana
00:14:52
and a calculation without would sliding of the encore wage
00:14:56
we obtain in it you know whether the value and the value of the stiffness
00:15:02
and the value of the ultimate strings and their ways that has sleep
00:15:08
possibility ads is wrong programs we obtain finally uh uh is this value
00:15:15
so uh for the steepness there is the um
00:15:20
smart violation and but that considering the
00:15:24
uh uh this cranks degrees finally a similar wizard in the two case
00:15:30
and now i it was if you she and yeah in
00:15:34
um eh in nye in a two thousand and fifteen
00:15:39
in two thousand and fifteen or think or what's up sabre
00:15:43
oh on the street ways that uh this flash
00:15:48
of around the eight centimetre and final day after excavation you
00:15:53
go rob salmon as are the drawbacks i wish
00:15:57
was that a moby guys doing this uh a sink or
00:16:02
uh observation anna finally uh as
00:16:08
the efficiency of the metadata
00:16:11
uh was uh uh the most late and the technical department of the mass say
00:16:16
uh decide to repair the structure with the same joe synthetic technique
00:16:23
and the last uh example uh if you're if possible okay
00:16:28
so the conclusion uh for our for this example was
00:16:32
has explained is the value of this project that
00:16:36
uh the joe tex side that does not work until locality why that
00:16:41
to the so fast it was a case in the two thousand
00:16:45
and fifteen when the joe tex i place it or
00:16:49
and tears or repairing of the street is not often that a
00:16:53
sink or is actually upset over and over again falsetto
00:16:58
and uh without the mythical lose investigation and this case is that
00:17:03
we would be still unaware of the juice entity community there
00:17:07
and say what action of the design apportion within the last uh twenty six euro
00:17:12
show is is a case of applications that the wizard are quite similar
00:17:18
and the last that example is a example of
00:17:22
michael we enforce meant by continues fibre
00:17:26
and this technique is uh uh the text or a a
00:17:30
is due to a it to enter the flat on
00:17:34
it was a innovative process and uh sayings to the
00:17:38
use of a continuous for yourself five else
00:17:42
well underneath distributed uh in us on mass this is uh the fell so
00:17:47
kind of application uh is is a um a weighting things to do
00:17:52
but finally a um a more interesting uh application is the
00:17:58
installation of a gas tank like uh he uh i
00:18:03
because the the the protection with the sixty centimetre
00:18:08
only yeah oh michael we enforce it sand
00:18:11
is equivalent protection too early yeah of a one meter
00:18:18
so this is a is a structural in the two thousand and sixteen
00:18:23
and there is only one problem with this kind of a
00:18:27
technique is as the visitor decision uh of uh
00:18:32
the cover due to the eh efficient very
00:18:36
nice of course of a a sound
00:18:41
so in happy to uh to south than in sixteen what decide
00:18:45
to remove those and michael ian faucets send an idea
00:18:49
for an improvement of the tank seismic stability but in no way for
00:18:54
problem we that that to the protection they are like the stick
00:18:58
and so this is a is the this technique while uh what's yours and
00:19:03
the final day of a building of the michael we enforce that cover
00:19:08
what's uh exactly adds a it was a initially yeah
00:19:13
this is a construction is in a in
00:19:18
now uh it was i was on the sixteen of uh the new core
00:19:23
so finally the performance of sound we have also by continues five else is amazing
00:19:29
the rancher possible application is wide and for
00:19:33
tonight is industrial development is far below
00:19:36
which it deserves about edging of fido you
00:19:40
could find information in insulator at your
00:19:45
so i i this is my conclusions uh application of joe's
00:19:49
and it takes a an environment that angela technical
00:19:52
engineering is place and play a matter technique and a
00:19:57
supported by a bar designed it so it's
00:20:00
uh many cases stories can be used as references and we
00:20:05
want to encourage the younger c. v. engine you
00:20:09
and to carry out an uh a walking a an
00:20:13
uh cases stories and this is important also
00:20:18
to be aired up and associated juice entity the where it
00:20:24
you know not to testify to the long term performance of a joe's entity else words
00:20:30
as this uh research was sustained by
00:20:34
um some uh uh manufacturing lab
