Research on influence of constraint shear wall on failure mode and energy dissipation performance of SRC frame-bent structure
Pseudo-dynamic and pseudo-static tests of SRC frame-bent model structure, and pseudo-static test of typical SRC abnormal joints are conducted to analyze the influence of constraint shear wall on the failure mode and energy dissipation performance. The results show that: the shear wall could be the first seismic line of the structure and the failure model is helpful to resist earthquakes; the weak part of the structure is down from coal hopper floor and operation floor to bottom two stories with the increase of the earthquake intensity; the load-displacement hysteretic curve is plump, and the energy dissipation performance is better; the shear wall has the significant restraint effect for the crack developing of SRC abnormal joints, and setting constraint shear walls along both vertical and horizontal direction could improve the failure mode of this kind of joint; setting constraint shear wall could enhance the energy dissipation performance, carrying capacity and ductility performance of SRC abnormal joints obviously. The research of this paper could provide the basic research data to promote the application of SRC frame-bent structure.

Abstract：Pseudo-dynamic and pseudo-static tests of SRC frame-bent model structure, and pseudo-static test of typical SRC abnormal joints are conducted to analyze the influence of constraint shear wall on the failure mode and energy dissipation performance. The results show that: the shear wall could be the first seismic line of the structure and the failure model is helpful to resist earthquakes; the weak part of the structure is down from coal hopper floor and operation floor to bottom two stories with the increase of the earthquake intensity; the load-displacement hysteretic curve is plump, and the energy dissipation performance is better; the shear wall has the significant restraint effect for the crack developing of SRC abnormal joints, and setting constraint shear walls along both vertical and horizontal direction could improve the failure mode of this kind of joint; setting constraint shear wall could enhance the energy dissipation performance, carrying capacity and ductility performance of SRC abnormal joints obviously. The research of this paper could provide the basic research data to promote the application of SRC frame-bent structure.
