Experiments Study On Stiffness And Ductility Of Short-leg Shear Wall

Short shear wall structural system is emerging in recent years as a structural system,its own makes a lot of advantages of the present structure of the system in the country to promote non-earthquake zone have been well received by the developer favorite,will be widely applied.However,the short shear wall of the research is still very full and not have a complete set of design theory and methods to guide the design of the project.Therefore,the systematic study of short-shear wall structural performance in engineering design has become an urgent need to resolve the issue.This article 12 of the short shear wall components,as well as a special-shaped columns and sample 2 general shear specimen for testing,in the cyclic loading tests carried out research and analysis,focused on its stiffness and ductility Characteristics. Draw some valuable conclusions for the short shear wall structure provides the basis for the design.This paper reads as follows:(1) based on the pattern of 1:2 ratio of 6 T-shaped short shear wall,the wall common component 2,6 L-shaped short shear wall component test,an analysis of test results revealed A variety of different types of components of the hysteresis curve characteristics.(2) respectively for T,L-shaped cross-section of the specimen through a list of comparative mapping.To reveal T,L-shaped cross section and stiffness with ductility different than the cross-cutting,axial compression ratio,such as changes in the characteristics and laws.(3) T-shaped and L-shaped cut-off pieces of the interview,because of their geometric asymmetry,resulting in a sample by force and energy of the asymmetry,the analysis of asymmetric performance characteristics,pointed out that the asymmetry of the structural design of the Impact.(4) 2 General specimen wall stiffness and ductility for analysis.(5)) for the T-shaped cross-section of the specimen will be short shear wall compared with ordinary wall.Sum of its Stiffness and ductility and at the same distinction.(6) cross-section of different forms(L-shaped and T-shaped),short pier shear wall components for analysis and comparison of the total.Find out the stiffness and ductility of common ground and differences.In addition,the seismic response of the solution,and the author of the popular in recent years,the precise integration method also made some improvements to make it more convenient to use.
