Abstract:
Earthquake resistant provisions of the San Francisco building code were met by the exclusive use of reinforced concrete in the construction of eleven 13-story apartment buildings. The X-shaped apartments have flat-slab floors with wide flat beams over corridors. Exterior walls are of the bearing-wall type without columns. Many interior partitions are of reinforced con-crete to resist vertical as well as horizontal loads. An advantage of the interior bearing wall system is that lateral bracing for earthquake resistance is increased at little extra cost. It was estimated that the extra cost of earthquake resistance was only 1 to 2 percent of the total, as compared with otherwise sound minimum construction, due to the structural system chosen.
