Abstract:
An experimental program is summarized which is aimed at enhancing the knowledge base regarding seismic behavior, analysis, and design of precast concrete shearwalls. The "emulation design" and "jointed construction" philosophies are described and an idealization of the behavior of precast shearwalls presented. A compendium of connection details for precast concrete shearwalls, seven for vertical joints and four for horizontal joints, is selected for further study; the selection process is described. The connection details are proportioned for a prototype shearwall that is designed as part of a six-story precast concrete office building. A description of all connection details and test procedure is given. Highlights from the cyclic load tests of the vertical joint specimens are documented, including connection resistance, displacement response, initial stiffness, and energy dissipation capacity.
