Study on Shear Performance and Loading Carrying Capacity of Strain Hardening Cementitious Composite Member
摘要
Abstract
In order to understand the shear behavior of strain hardening cementitious composite(SHCC)member and provide the technical support for its application in engineering,the experimental investigation of SHCC member with shear span length to effective depth ratio about 3 was carried out,in which the shear failure behavior of SHCC member was analyzed,including shear load versus displacement,crack propagation,ultimate fracture pattern and fracture surface.In addition,based on the contributions to the shear bearing capacity of SHCC member from both the matrix contact effect and fiber bridging effect on the crack surface of SHCC,a calculation method for the shear bearing capacity of SHCC member considering the matrix contact effect and fiber bridging effect on the crack surface of SHCC is proposed.The research has shown that the shear bearing capacity of SHCC member can be obtained by separately calculating the shear bearing capacity of the matrix contact effect and the fiber bridging effect on the crack surface of SHCC,and the proposed formula for calculating the shear bearing capacity of SHCC member is effective precise.关键词
