Dear All, I was going through a design of industrial shed with concrete columns till roof(around 7m eaves height). The roof sheeting is supported by rafters which rests on the concrete columns connected by a base plate. My question is, do I need to check lateral deflection of concrete columns...
I was checking columns for a ground villa where they have increased the floor height by 1m more than the approved height.
Many columns are failing in buckling now. However, when I change the column thickness from 200mm to 250mm, the columns passed the buckling check.
My question is regarding...
The question is regarding the 'beams on elastic foundation' modeled in SAFE program.
Does anyone here has noticed the 'rotational spring constant/unit length' in 'line spring property data' in SAFE v16(beside the 'vertical spring constant')?
What value should be provided there and what is its...
Hello all.
I was reviewing a concrete slab layout and would like to get your views regarding the load transfer mechanism here.
Will the cantilever slabs will be supported on the center slab here(this is what I presume)?
How much width of 500mm slab will be effective for carrying those slabs?

Referencing the above thread, should I check the punching of slab for the Axial Load in column subtracted by shear carried by beam for the full perimeter even if the beam connects to a small part of the column?
I am not actually getting the idea of punching shear failure for...
Dear all,
I have to clarify the load combination to check overturning affects for an industrial shed footing. The reaction for different loads provided by steel designer are attached in the picture. I just need to confirm that when I use a 0.6D+W combination, do I apply "0.6" factor to...
Dear all,
Below is the attached picture for the design I pursue. Basically, client wants to make a boundary wall in front of existing wall due to some issues. Now he doesn't wants to use RCC for design and insists to use the Solid Block work to support soil horizontal pressure. I am not much...
thread507-424372
Referencing the above thread; I understand the deflection and moment transfer issues at joint. I am just curious about the joint detailing in this case and similar case when a slab cantilevers directly from beam(the beam will be supported by columns obviously). Does the tension...
Dear Members, I came across a detail(attached in picture) for a cantilever canopy which doesn't seem okay to me. Would like to know your views about it. What I believe is that the cantilever bars should at least develop inside the beam as per the required anchorage length and beam should be...
Hi Everyone,
I was recently checking a pile cap and when I tried to check one way shear at distance 'd' from face of column, the section falls outside the pile cap. How can I check shear in pile cap in such situation? Similar way, what if the punching shear perimeter also falls outside the pile cap?
Does any code has limitations on reduction in column/wall sections from base section? The building I am reviewing has a lot of columns and walls changing size regularly along its height. Even though all the requirements for strength and serviceability are met, I am still worried if the reduced...
Good Morning Everyone,
I have got a project wherein the client wants to make an additional floor over the existing ground floor structure. When checked, the footings need to be increased in size due to additional loads. The client also doesn't wants to extend his footings on all sides and...
