A simple spread sheet for calculating Earthquake base shear for building as per IS1893-2002. EQ base shear can be calculated  based on the parameters provided by users as per IS1893-2002 including building height, base dimension, type of building, zone, type of soil condition etc. It also provides the distribution of storey shear along the height of the building as per Wi*Hi^2 relation. The graphs of time period v/s height as per the empirical relation in the code are available for different base dimension of the building.

I hope it will be helpful  for structural engineers to quickly calculate storey shear and base shear. The ``help`` is available in the spread sheet.
