Experimental And Theoretical Analysis Of Normal Section Strength Of T-Short-Leg Shear Wall

In recent years,short-leg shear wall structure has been used in part of the non-seismic region of our country.However,the seismic performance of the structural system in the areas of theoretical research has been lagging behind in the engineering application.So more in-depth theoretical study of the test is very necessary.For the cross section ultimate bearing capacity of T-Short-Leg Shear Wall has done a certain amount of work.However,the experience of the question is still very lack,and necessary to refer to general shear wall structure and the special-shaped column cross-section structure.It is necessary for the T-Short-Leg Shear Wall structure is to conduct in-depth study of bearing capacity,and to find a unique formula.Based on the above,the specific work done by the following:1),With the design of different parameters,carry on the short-pier shear wall experimental study under low-cyclic loading.And find the changing rule of specimen failure process,ultimate bearing capacity,ductility,hysteretic curve,skeleton curve.2),Estimating the ultimate bearing capacity of specimens before the experiment. Compared with the experiment results,analyzing the feasibility of Simplified calculation method.3),Established a multi-component model of T-Short-Leg Shear Wall,analyzing the stress-strain relationship of weak region compressed bar.4),Improved the plane section assumption,found the strain curve of T-Short-Leg Shear Wall web and flange under the low cyclic loading.And the changing rule of neutral axis height.5),According to experimental analysis,found the strain curve of T-Short-Leg Shear Wall web in limit state,Summed up to T-Short-Leg Shear Wall experience formula about the ultimate bearing capacity calculation.
