The same thing for the other one too but, that one is on the top right in red. I'm not sure about the fire escape part (I have to ask but looks like it is) regardless the architect doesn't want steel staircase and it has to be cast in situ concrete.
thank you for your response. 40cm is AR limit but in order to limit span/20 requirement, I was forced to give it 70cm due to code limit. (minimum thickness of wall for medium ductility class in eurocode is max of 0.15m or span/20). If I'm not expected to satisfy that and provide low ductility 20...
I have a wall in a seismic area that is part of a building and should satisfy the following eurocode provision.
The wall supports a stair and the beginning and end of the stair is connected to the RC frame system and floor diaphragm.
The wall height is 14m (4 floors each 3.5m center to center...
I have an existing structure (belt conveyors and its pier and footings, both steel and RC). It transports materials from downstream (near river) on a very steep slope. Previous geotech investigation found out that top layer is basaltic and the lower one is conglomerate. Their conclusion is there...
the top surface is a tensioned surface between the arcs and the lower part is a curved downward dome . I don't have a parameter for the curved part. (other than the radius of the projected curves (the two arcs at 60°). But I will have a smooth transition between these two. (a fitting curve here)...
Sorry I know its disrespectful to ask a question and be silent. I apologize but I didn't know how to respond.
1. The top level of my so called "dome" and the half circle are at the same elevation so if i try to cut the sphere with the curve (beams) all of the top surface will be removed (for...
go to your original model folder and find a file with an extension name of $et and open it. Search "LOAD CASES" and start from $ LOAD CASES up to the end of $ LOAD COMBINATIONS (not the start but the end of load combination) paste it (overwrite) it to your newer $et file. In case you make...
Yes, I couldn't do that for the same reason you said. The next question will be how to create that curved surface( the part to be removed) as it is, in which I don't know how to do that. Even after that I don't think I could have all the meshes have a node at the curved edge in which I have a...
No its not. Originally, those three circles were ellipses. (the major and minor radius of the ellipse are nearly identical that's why I wanted to simplify). I'm a Structural Engineer and this shape is given to us from the Architects. Those three Ellipses represent a support structure (beam) and...
I don't know if this belongs here but,
I want to create a shell structure created by three half circles vertically rotated at 60°. (see attached image). So, is there any easy way/tool to create this meshed shell? (I will use it elsewhere for complete structural analysis.) So far I have tried...
This might be silly but, me and my friend have different understandings. Is simply supported two slab
a. discontinuous at all four edges only or
b. if the shorter direction is simply supported and longer direction continuous, the panel is classified still as simply supported
we're using...
We have a two basement building to be constructed near a G+7 building (total height = 24m. Due to the slope of the ground, we are to excavate 11m near this building. Initially we were going to provide shoring but we chose to remove 1 basement near the existing building (not as a whole but near...
Our original design shows a skylight on top of 3m by 3m opening formed out of a 20cm RC Slab. At the edges of this opening we provided 60cm RC parapet to bury bolts for receiving plates with RHS Post. The client has requested us to change the skylight to glass walkway excluding the parapet. (Has...
I have a Contractor submitted drawing of hollow concrete slab with PVC pipes for approval. Sorry this is not common in our country, but, is the design the same as Hollow Concrete Block or the PVC pipe has a unique function? Does it act like composite structure? Also any good reference?
