Seismic Design of RC Structural Walls. Part II: Applications

Abstract

Design calculations are presented for two shear-wall buildings using a new code format described in a companion paper. The lateral force resisting system for building 1 is comprised of two rectangular and two channel-shaped wall cross sections, and is typical of current U.S. practice of using relatively few walls for lateral load resistance. Based on the proposed code format, special transverse reinforcement is required at the boundaries of the rectangular wall; however, no special transverse reinforcement is required for the channel-shaped wall for loads parallel to the wall web. The lateral force resisting system for the second building is comprised of rectangular and T-shaped walls. Although no special transverse reinforcement is required for the rectangular walls, a moderate quantity of special transverse reinforcement is required for the web of the T-shaped wall. Wall design requirements for building 1 are also compared with UBC 1991 design requirements. The design information presented for the two buildings reveals the flexibility and versatility of the proposed design format described in the companion paper, and indicates that the proposed design format will reduce construction materials and costs for most applications compared with current design requirements.
