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...
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?
Why is the total longitudinal reinf. of a beam reported by Etabs not equivalent to
the summation of longitudinal reinf. due to shear + torsion + flexure
Individually it gave me
Flexure = 7362mm²
Shear = 6580mm² and
Torsion = 215mm²
----Total = 14157mm²
but a Total of 14862mm² (off by 705mm²)...
What is the general thing to do incase two modes are too close to each other? Eurocode 8 requires two modes (both translational and torsional modes) to have at least 10% of the higher period gap.
As stated on (Eurocode 4.3.4) seismic displacements from linear analysis should be multiplied with displacement amplification factor equal to q (behaviour factor). So my question is, do we need to manually amplify the storey drift reported by etabs with the behaviour factor or is it...
I have an RC Pipe and I want to apply parabolic loads to its base and see its response. So far I have been told to approximate it with equivalent trapezoidal loads. My problem is the slope of the curve changes rapidly(narrow curve)that I would need too many approximations. So, is there any FEA...
I have a 30mx13m Rapid Sand filter and a valve room (part of a water treatment plant) as indicated on the image below.

I have modelled the entire structure as 3D on gmsh (a meshing software) meshed the...
I have a brick wall in between two RC walls as displayed on my image. Both the top and bottom RC walls (drawn in red) are laterally restrained. The main purpose of the brick wall is that individual bricks can be easily removed during construction inorder to make small holes so that the water...
Whenever I export shell force and stesses to excel in Sap2000 v23, the outputs are all exported as computed from individual elements (unaveraged), but, I want to export the averaged ones to excel. (I can see it on the graphical output window, But,I want to export that to excel). So, is there an...
I am trying to design an RC Pipe culvert to AASHTO LRFD, SI Units 12.10 and trying to plot heger pressure distribution on an RC Pipe and I am having difficulties understanding it. So, my questions are: -
1. In the this picture, is my understanding of A3 correct?
If so, here i got y1 negative...
