    questions on GSA PCADG rules

    A building with perimeter columns move in 4.5' from the edge of the building, is it to avoid removing the coulmns to satisfy the GSA progressive collapse guidelines? That is, if the perimeter columns are moved 4.5' or more inside the edge of the building there is no need to do the GSA...

    Scaling of Dynamic Base Shears

    Per ASCE7-05 sections 12.9.2, 12.9.4 and 12.12.1, for drift calculation the only criteria need to follow are the requirements in section 12.9.2 and there is no need to match up any percentage of the calculated base shear using the equivalent lateral force procedure. For force calculation...

    Question on load combinations

    I am using a structural design program and I was surprised to find out that the program generated load combinations 1. have load cases considering live load = 0. for example, if using UBC97 eq. 12-5, there are load combinatios 1.2D+1.0E 2. When using eq 12-6 in UBC97, have load combinations...

    Question on redundancy and load combinations

    If a building has torsional irregularity, does the code require calculating the redundancy with the load cases considering the orthogonal effects?
