For concrete, the elastic modulus is defined similarly with other materials even for steel. The larger difference is that the concrete has relatively very low tensile capacity. Most of the practical design of the concrete members, concrete tensile stress is considered to zero. This means the modulus ...

I prefer Mathcad too. Tedds does the similar as Mathcad. Both Mathcad and Tedds are easier to check and to repeat the calculation. This can't be done by Excel explicitly since the equations are behind the pages. ------------------------------ Hengfeng Wang A.M.ASCE Struct Engr HOK New York NY ...

Normally, the compression and tension are different even through the dynamic analysis is used for some load cases. For example, the dead loads are always there. Both tension and compression shall be checked. HENGFENG WNAG, Ph.D Structural Engineer HOK 5 Bryant Park 1065 Avenue of the ...
