In the floor plan below, the rigidities of walls A, B, and C are 1.0. The rigidity of wall D is 1.5. For a force of 100 kips in the horizontal direction, determine the maximum diaphragm shear per unit depth (absolute value). Assume that the center of mass is at the center of the diaphragm. To obtain this answer you will first need to compute the location of the center of rigidity and the force in each wall. 10' 10' A 10' CR D 10' X B
