Does anybody knows something about the Earthquake mode option included in the RC Designer in STAAD 2006 (specially ACI check)? I asked REI, but they don't answer me yet?

I´m using Staad 2003, in the concrete design the software crashs trying to design beams. I made a hand-check and the moments and shears are in the normal range for the beam´s section, so there should be no problem. There is a solution for that? Regards

You should check very carefully the r value used by Staad. Probably, it's using r respect to principal axes.

Thanks for the info Vooter. I didn't know this problem because always used this software with soil above the foundation and dead/live loads applieds. I was checking the software and found that you can run it using very low values for soil depth, dead load and live load (I used 0.00001) and the...

Probably you need the Beava module. This module is able to generate critical condition for specific elements within the structure.

Few years ago I was using CONCISE during three years. It´s excellent.

I found the same problem. Checking the results, I found that the footing design was made for seismic or wind load ONLY (load case that produce a low P). To solve this I'm using the Load List command to include only the combos in the footing design. Regards

Hello: I'm looking some input about PEX pipes. I would like to know its performance compared to traditional PVC pipes in Residential Buildings. Thanks

Yes it is. Tanks behavior depends on diameter. You can compare results with Mamx=(1-1/(beta*d))*(gamma*radii*h*thickness)/(12*(1-poisson^2))^0.5 where beta=(3*(1-poisson^2)/(radii^2*thickness^2))^.25 In a tank, My will be positive and negative; in a cantilever beam will be negative always.

Thanks. I have Staad.etc. It design masonry shear wall following ACI-530 and I was trying to design it using ubc code. I don't have ACI-530. Do you know about big differences between both codes? Regards

I would like to compare UBC 97 and ACI-530 about boundary element requirement for masonry shear wall. I know that UBC require boundary element when compressive strain is greater than 0.0015 using factored load and R=1.1. I don't have ACI-530 can somebody explains me the ACI-530 criteria? Thanks

I would like to get a freeware to design masonry shear wall using ACI-530 or UBC 97 also I'd like to find the procedure to do this (by hand). Anybody knows where can I get it? Please help
