Abstract
Shear panel tests on corrugated steel diaphragms were carried out to examine elasto-plastic deformation behavior due to end failure action and tension field action under cyclic loading. Based on the test results, two types of elasto-plastic hysteresis model were proposed for each action. The hysteresis of end failure action was modeled as a bi-linear curve based on initial stiffness and end failure strength. Furthermore, the hysteresis of tension field action was modeled as a curve based on initial stiffness, load decreasing stiffness, tension field strength, and slip strength. Each hysteresis model provided appropriate estimation of energy dissipation for the test results.
