4- The building shown has four concrete shear walls as shown. The plan view and cross section show the arrangement and height of the walls. Walls 1 & 3 have the same length and height. 60' 30' 4' WALL 3 C 12' 50' WALL 2 WALL 4 WALL! SECTION 6-0 PLAN a) Calculate the relative rigidity (R) of walls 1 and 3 assuming the connections at the roof level are fixed, i.e. fixed-fixed case. b) Calculate the relative rigidity (R) of wall 2 assuming the connection at the roof level is considered free i.e. cantilever case. c) The seismic lateral force of 180 kips in the east-west direction was calculated for the given structure. Calculate the seismic lateral force that will be carried by each wall in the east-west direction (i.e. walls 1 and 3) assuming the diaphragm is rigid. d) The seismic lateral force of 180 kips in the east-west direction was calculated for the given structure. Calculate the seismic lateral force that will be carried by each wall in the east-west direction (i.e. walls 1 and 3) assuming the diaphragm is flexible.
