Research on the Deformation Behavior and Restoring Model of Energy-Saving Block & Invisible Multi-Ribbed Frame Walls

Abstract eng:
Six pieces of energy-saving block and invisible multi-ribbed frame walls of 1/2 scale were tested through pseudo static test. Based on the test results, hysteretic curves of shear force and displacement of the models were obtained and discussed. A general skeleton curve of shear force and displacement was formed on the basis of the hysteretic curves. The restoring model for the analysis of earthquake response of the energy-saving block and invisible multi-ribbed frame walls was eventually proposed. The deformation behavior of the specimens was discussed, and formulas for calculating the rigidity of the walls at different loading stages were proposed as well. The research showed that average lateral displacement ductility factor of the energy-saving block and invisible multi-ribbed frame walls calculated by test results was 3.16. This value illustrates the walls appropriately designed can fully meet the seismic requirement of the structures. Deteriorative quadrilinear restoring model of the walls fitted by test results can quite accurately reflect hysteretic behaviors and skeleton curves of the walls, and it can be applied to energy-saving block and invisible multi-ribbed structural earthquake response analysis.
