The above referenced Excel Software Tool is provided for distribution of seismic loads to Reinforced Concrete (RC) Shear Walls (SW) part of the Lateral Force Resisting System (LFRS) in Low Rise Simple Buildings assuming Rigid Diaphragm Analysis (RDA) assumptions, where loads are distributed to resisting elements according to their relative stiffness and location away from the Center of Rotation (COR) of the rigid diaphragm. These software tools use Metric (MPa or Mks – Kgf/cm2) Units.
