Does STAAD-PRO do reinforced concrete beam design? If so, which commands do I use? Thanks

I have a question as it relates to structural engineering. I am a PE with some structural expierience. I am now in a field which requires some structural design which is outside my area of expertise. Therefore, I am having to learn new things quickly as the design schedules are tight. I am...

Thanks for all the replys. Has anyone used his concrete column and beam spreadsheets?

Has anyone purchased or used the spreadsheets from this website? It looks to have quite a few spreadsheets with code references with the calculations. The author is Daniel T. Li. Thanks for the input.

According to the IBC 2006, there is an exception 4 which includes "hyrdraulic structures" Would this apply to buried tanks?

I am designing a two-way slab and want to use the direct design method outlined in ACI 318. The question I have has to do with the distribution of moments in the slab. I was thinking of just calculating the statical moment in each direction and basing my flexural steel design on that. This woulb...

Does anyone know of an alternate to using the Strut and Tie model for deep beams?

I am using an allowable shear stress of .85*2*sqrt(fc) to get allowable shear stress in psi. I noticed that factor changed in the new ACI to .75, but they do allow it in appendix c if you use there load factors. I assume it is ok to use .85 for now. Does anyone have any comments on this? T.

I am designing some reinforced concrete beams which are supporting a slab which will have 2-way action. Is there a method for determing the load to each beam? One beam is perpendicular to the other. The slab dimensions are roughly 10'x 10'. Thanks T.

Does anyone know of a good cost of living calculator to analyze the cost of living in a particular city? Thanks, Todd

Please see attached link from the USGS. This will give you the seismic parameters you are looking for. http://earthquake.usgs.gov/research/hazmaps/design/

Does anyone know where the resultant load of a trapoziodal load dist acts from the support? This is a cantilver beam with the larger load at the support. Thanks

I am looking for a rectangular plate chart which has a trapazoidal load distribution. I design a lot of rect tanks and have cases which have seismic sloshing. Thanks T.

The ACI 350 Code which deals with min shear reinforcement. It is section 11.5.5.1. This section gives requirements for using half of the allowable shear. Does this provision apply to below grade walls resisting soil loads as well as walls resisting liquid loads or is this just meant for beams...

I just had a value engineering session on one of my jobs and they came back with a few comments. See below: If anyone has some suggestions on how to respond, I would appreciate it. 1. Eliminate upturned keys in concrete starter walls. 2. Reduce wait time between adjacent concrete placements...
