Housing Report: Reinforced concrete frame with concrete shear walls – dual system

This housing report looks at housing typologies in Syria, with a focus on reinforced concrete frame with concrete shear walls - dual system. These buildings are characterized by a combination of shear walls and frames in both directions. The buildings are multiple housing units found in the main cities of Syria. The shear walls are often part of the elevator and service cores, whereas the frames are arranged in-plane, in conjunction with the walls, to support the floor system. Stiffness and mass distribution are irregular and the majority of buildings may experience soft-story or torsional problems. As a result, these buildings are expected to have only moderate seismic resistance.
