Hi All,
I have used StaadPro to do steel analysis. But i have some problem in assign the effective length of column. I have assign KY=2.0 and KZ=2.0 but when i check the design output the buckling calculation effective length still the same ==> K=1 . However the effective length under section...
Recently I want to calculate the base moment of one barrier. But I have some doubt find out the bending moment at the fix end for 1kN/m2 infill load. The object is standing 10 meter high with the length of 8 meter. Kindly assist for this simple structure analysts. Attached the sketch.
Many...
We want to adopt release well in piling stage. I have some doubts of it.
1. Is there any design criteria or guideline for release well.
2. How to determine the well location, depth and size.
Appreciate for your comments and replies. Thanks[bigsmile]
We have one project which need excavation for padestrian underpass. The underpass is below the road level about 20 meter and the length of the underpass is about 15m. So i'm thinking to use sheet piles to drive in and then strut with king post. i'm estimated the driven will need about 40m from...
Recently we are planning to park a mobile crane on the casted rc slab. But how we can check / determine if the rc slab can taking this load? I'm trying to check the deflection and punching shear on rc slab. Is these checking enought to determine the slab can taking the load? Thanks for advice.
Hi, I’m green in design and need yours some advice. I have some doubt regarding to rise up pile cap and combine with the beam and slab. When doing the design all elements is separated slab, beam and pile cap. But now all combine is that will affect the original design? I enclosed the sketch for...
I will construct a biofiltration rain garden on my project. This is fresh to us. I just study the plan and that are few layers of the gravel and sand then reach the overflow pipe. Any body have done it before and have any spec have to take note? Have any method to construct it? Appreciate yours...
Recently I deal with one project that need to enlarge the existing footing due to the additional loading. I have some doubt to design it.
1.Is it possible to enlarge the footing because I’m not allowed to remove the existing footing?
2.The new footing area is base on the existing footing...
I have some doubt in steel design. Normally i based on the plastic modulus Sx= M/Py to find the steel section. But in case of c-channel, the channel must put in the "C" manner would be effective. If let say put in "n" manner and the load come in vertical, so is that i need to base on Sy to...
Recently I analysis a combined pad footing. The combine pad footing has two stumps which is the one of the load is greater then another one about 3 times. The lighter load is uplift force. Could anybody help me?
1.Do I need to consider the uplift force in design the combine footing? If need...
Recently i'm doing a calculation involved the cantilever sheet pile for temporary earth retaining structure. Actually my excavation depth is 2 meter and the embedment depth is 2.1 meter. I get the max. bending moment =42 kNm/m. Now my question is how to get the:-
1) Lateral deflection.
2)...
