"IBC2000E" is a spreadsheet program written in MS-Excel for the purpose of seismic loading analysis for buildings and various nonbuilding structures, as well as architectural, mechanical, and electrical components per the IBC 2000 Code. Specifically, the total base seismic shear for buildings and nonbuilding structures is calculated. For Multi-Level Buildings, the vertical distribution of the total seismic shear is also determined, and a drift analysis can also be performed. The seismic restraint force for various components is also calculated.
