I am trying to calculate the maximum design force for coupling beams in my building with ETABS. My question is even though it is stated in section 18.10.4.5 that the maximum allowable shear force is limited to 10.Acw.sqrt(fc'), the program calculates the maximum allowable shear force with...
I am trying to design a special concrete shear wall. The boundary zones of the wall needs to be approximately %60 of the total wall length so there is not much space left for panel zones. In NEHRP document it mentiones that the wall can be composed of pre-tied modules that can be connected prior...

I am continuing structural/nonstructural design of a base isolated structure. Time history analysis (3D) gives reasonable results, however when i try to obtain the floor spectra there are sharp peaks (around 1 g whereas average acceleration is about 0.2 g for other periods other than resonance...
I am trying to define hinge properties for steel columns according to FEMA 273 Table 5-6 in SAP2000. Calculating yield moment, yield rotation and other needed paremeters under changing axial load levels are understandable. But when it comes to defining moment-rotation relationship (considering...
