Abstract
The objective of this investigation is to develop practical methods for the aseismic design of combined frame-wall structural systems. To achieve this objective, integrated analytical and experimental studies have been conducted to determine the actual mechanical behavior of wall systems subjected to earthquake-like excitations. Rather than using the existing facility for determining a structure's overall response to specific time-history ground motions, a new structural loading facility capable of simulating earthquake effects, was developed. Significant subassemblages of the structural system were tested rather than large-scale models of entire buildings. Predicting the in-plane seismic behavior of frame-wall systems requires information on the variation of the lateral shear-displacement relationship for each story. In order to correctly simulate the actual boundary conditions of a particular story, subassemblages of at least two or three stories were tested. The principal feature of this facility is its ability to pseudo-statically simulate the dynamic loading conditions which could be induced in subassemblages of buildings during earthquake ground shaking.
