HORIZONTAL RESISTANT MECHANISM AND RESTORING FORCE CHARACTERISTICS OF CHECKERED PATTERN SEISMIC RESISTANT PANEL WITH SANDWICHED USING PLYWOOD AND STEEL

This study suggests a new hybrid seismic resistant wall constructed of steel stubs sandwiched between plywoods with steel joint hardware, and each wall panel is arranged in a checkered pattern. Here, to investigate the resistant mechanism and restoring force characteristics, horizontal loading tests are conducted as parameters with composition of hybrid panel. From the test results, the combined effect of bending resistant of steel stub and embedded plywood is confirmed, and this effect is influenced by the steel joint hardware. Furthermore, the analytical method of strength is proposed, and it can estimate the test results.
