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]

After i have read all your comments. I think my case is suitable for soldier pile with sheet pile lagging. But im wonder how the sheet pile lagging can be done... because i honestly said im fresh in temporary retaining. Have anybody have the sequence / method of work? for dcarr82775, there...

Thanks all. BigH, Do you have a copy of NUS conference? Appreciate if you can share it with me. Thanks.

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...

Thanks all your advice. We have made it and all work done smoothly.

Should be about 3000mm.

hi hokkie, the rebars is base on the construction drawing. The outrigger load is about 100KN each. I don't have any FE software to analysed.

Thanks all. The suspended slab was casted more then 3 months ago and had achieved the required concrete compressive strength.The crane have outriggers. But base on the crane loading i have check and assume the outriggers will park on the middle on span, then it must required at least 1700mm2...

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.

Dear all, Thanks to you all comments. Dcarr : Offcource the shear link for the beam will go in the pile cap until the column interface. hokie66: to rise up the pile cap is to minimise the excavation depth. tngv: The beam will not seperate out but in continous as early design. Thanks.

Hi msquared48, I think you get my point. The column reinforcement is go up from the center line of pile cap. The beam is pin to the column / pilecap if the beam rest on the top of pile cap. But i'm not sure is fix if the beam go thru the pile cap.So if that is the case is there are any...

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...
