Apply a 24 kip horizontal earthquake load at the second floor diaphragm and 48 kip horizontal earthquake load at the roof diaphragm in the East-West direction (direction of gridlines 1 through 4). You may assume that the weight of the structure is uniformly distributed, so these loads may be applied as a uniform distributed load (klf or plf) to the side of the diaphragm.

Determine the internal forces and moments at the ends of each beam and column in the moment frames caused by the earthquake load. Draw the corresponding shear and moment diagrams.
