- Abstract
- Research was conducted in the area of seismic behavior of frame-wall and infill frame structural systems, investigating the seismic hysteretic behavior of R/C structural walls, and the effects of engineered masonry infill panels on the seismic hysteretic behavior of ductile R/C frames. Integrated analytical and experimental studies were conducted in both investigations to develop practical methods for the aseismic design of combined frame-wall structural systems. In the studies of the hysteretic behavior of R/C structural walls the main objective of the analytical studies was to develop efficient computer programs for the analysis of multistory frame-wall structural systems. The experimental studies sought to obtain reliable data regarding the linear and nonlinear (particularly the hysteretic) behavior of frame-wall structural systems. The experimental program covered the testing of framed and frameless single and coupled wall systems. To conduct these experiments, a special loading facility was developed. Its principle feature is its ability to simulate pseudo-statically the dynamic loading conditions which could be induced in subassemblages of buildings during earthquake ground shaking. The experimental phase of the second investigation consisted of pseudo-static cyclic load tests on a series of 1/3-scale model subassemblages of the lower three stories of an eleven-story, three-bay frame with infills in the two outer bays. Its analytical phase was to develop and use theoretically sound macroscopic mathematical models capable of describing essential aspects of the observed hysteretic behavior of engineered infilled frame subassemblages subjected to pseudo-static cyclic lateral loads.
