Seismic Force Calculator is a software that calculates seismic force parameters according to NBCC 2015.  The whole process is straightforward in a one-page interactive form. Users should enter input data such as province and location of the building, site class, and so on and the program will calculate all seismic results such as design spectral acceleration, design base shear, fundamental period of the structure, and laterally seismic forces for each storey.
