Analysis On Mechanical Behavior Of T-shaped RC Steel Reinforced Concrete Short-pier Shell Wall

As a kind of lateral foce-resisting members,Short-pier shear wall structures have the merits of special-shaped column and shear wall.In recent years,this structure systerm was widely used in high residential building in China.When the non-central load induced upon the T shape Short-pier shear wall,its mechanical properties between pulling the web plate and pushing he web plate is very differen.When the web of short-pier shear wall component is pushed,the supporting capacity is quite high,the ductility is good and the type of failure in the structure is large eccentricities;while when the web is pulled,the supporting capacity is low,the ductility is misses and the type of failure in the structure is small eccentricities,the failure of the member Probably is brittle.Cause the direction of the earthquake is uncertain,the littler axial comPression ratio have tobe adopted in the code,then materials will not be made full use.To change the mechanical performance of T shaped SRC short-leg shear wall,shape steel was embedded at the end of the web,hoping to optimize the supporting capacity as far as Possible.The following are the Prime tasks in the thesis:1,Introduced respective characteristics and research status of Short-pier shear wall structure systerm and Steel reinforced concrete,proposed the improvement plan in view of the conventional T shaped Short-pier shear wall's mechanical properties asymmetrical characteristic:shape steel was embedded at the end of the web,Then T-shaped RC Steel Reinforced Concrete Short-pier Shell Wall is put forward in the thesis.2,Explained the test of T-shaped SRC short-leg shear walls in the laboratory,showed the whole failure Processes observed,analyzed prime solution of the test,including the supporting capacity and the curve of the load-diceplacement.The ordinary T shaped Wide-pier abnormity column's tentative data has carried on the comparison with the literature. 3,Use the ANSYS software to establish the three-dimensional models for the T-shaped SRC short-leg shear walls tested in the laboratory.Then contrastive analysis of the results from the testing and computation was taked,confirms the feasibility of the ANSYS models.4,Based on the analysis result of ANSYS and the test,with reference of related data,the supporting capacity of T-shaped SRC Short-leg shear walls'cross-section was studied,and gives formula which may be used for reference refers to the formula in the code.
