Calculation of seismic loads for analysis of structure is required when earthquake resistant structure is to be designed. Structural Engineers use different design codes/guidelines for calculation of earthquake loads. Widely accepted codes for calculation of seismic loads are, Uniform Building Code 1997 (UBC-97), International building code (IBC), ASCE-7-10, Building code of … [Read more...] about Seismic Loads for Design of Structures (UBC-1997)
