Hi, I'm studying the floor vibrations on a model that consisting of three floor A, B and C, despite floor A and C are symmetric, they show different ultimate acceleration because STAAD considers one of the girders only for calculating the results of…

I'm trying to model the attached floor system, and I need to make sure following points: 0- Can I draw the composite deck to cover all the floor area or do I have to draw it for every panel in the floor. because when I'm trying to cover the whole…

Good Day, I have done a seismic analysis and noticed the following note: ***NOTE: SEISMIC LOAD IS ACTING AT CENTER OF MASS FOR RIGID DIAPHRAGM. TORSION FROM STATIC ECCENTRICITY (esi) IS INCLUDED IN ANALYSIS. DYNAMIC ECCENTRICITY APPLIED = DEC -…

Good Day, I am currently modelling a staircase supported by a moment frame and I have come across a strange occurrence. When I checked my column forces the axial forces seemed alright but the moments were strange as the moments generated along the…

Good Day, I have analyzed and designed a shear wall following the ACI code in Staad and would like to clarify some results.. The shear wall design has reported Edge reinforcement, however the length of this edge or boundary zone has not been reported…
