Experimental Study on Hysteretic Behavior of Steel Plate Shear Wall with External Strut
摘要
Abstract
The tension field of steel plate shear wall has an adverse transverse effect on the frame column,which is easy to lead to the advance failure of the column,and the steel plate has an embedded effect on the bending deformation of the frame beam,which makes it difficult to develop the plastic hinge and implement the"strong column and weak beam".To solve this problem,a steel plate shear wall structure with external strut is proposed in this study,which is composed of strut,inner frame and steel plate.The inner frame and the steel plate constitute the steel plate shear wall unit,which is connected with the main frame through the strut to form the lateral force-resisting structure.The tension field of the steel plate shear wall unit is used to provide the main lateral stiffness and bearing capacity,and the force of the tension field is directly transferred to the beam-column joints of the main frame through the strut,thus eliminating its adverse influence on the frame column and avoiding the embedded effect of the wall plate on the frame beam.Based on the mechanism of the structure,the formulas for calculating the shear capacity and the axial force of the strut were derived,and two steel plate shear walls with external strut and one comparison specimen without wall plate were designed.The hysteretic curve,skeleton curve,characteristic load and displacement were obtained by quasi-static test.The ductility,energy dissipation,bearing capacity and stiffness degradation were analyzed,and the yield sequence and failure mechanism of each component were determined.The results show that the new structure has better hysteretic performance,and the global instability will not occur during the whole loading process.The crack penetration of the steel plate under the cyclic load controls the damage of the strut.The formulas for calculating the axial force of the strut and shear capacity are in good agreement with the test results.关键词
