Structural Walls in Earthquake-Resistant Buildings: Dynamic Analysis of Isolated Structural Walls. Development of Design Procedure - Design Force Levels

摘要

A procedure is used to establish estimates of stiffness, strength, and deformation demands of isolated structural walls subjected to ground motions of varying intensity. The investigation characterizes earthquake ground motions to select critical input motions; identifies the most significant structural and ground motion parameters; and formulates a simple design procedure for correlating earthquake demands with structural capacities. The computer program that was used to analyze the variables, DRAIN-2D, is described. The compilation of maximum or near-maximum values of the significant response quantities is shown to be a major step in determining design force levels for earthquake-resistant structural walls. The procedure, which is based on fundamental period and flexural yield level, is illustrated for the case of twenty-story walls subjected to input motions.
