Calculation of base shear and its distribution along the height for response spectrum method in IS 1893 (Part 1) : 2016 V. The beam is subjected to a udl of 30 kN/m. TOR SION indicates that the torsional moment (in the horizontal plane) arising due to eccentricity between the center of mass and center of rigidity needs to be considered. Dynamic Response Spectrum Analysis Shear Plane Frame Page 1 of 33. Dynamic analysis uniform support motion response spectrum method. These analysis are carried out by considering different seismic zones, medium soil type for all zones. as per IS 1893:2002 and IS 1893:2016. A concrete gravity dam of different heights 70 m, 90 m and 110 m model is prepared in STAAD-PRO to perform the time history analysis and response spectrum analysis.

Using ETABS nonlinear time history analysis is performed on the proposed building.
