摘要:
为了对钢筋混凝土(RC)框架结构的地震破坏机制和抗震性能进行控制，将纤维增强混凝土(FRC)用于框架结构的预期损伤部位．采用有限元软件ABAQUS 对RC 框架结构和预期损伤部位采用FRC 的框架结构进行弹塑性时程分析，研究预期损伤部位采用FRC 框架结构的地震破坏机制和抗震性能．结果表明，FRC 框架结构能够推迟结构柱铰的出现，有助于框架结构形成整体破坏机制；FRC 框架有良好的变形能力，对变形控制能力优于RC 框架；其塑性耗能能力大于RC 框架结构．
Abstract:
In order to control the failure mechanism and seismic performance of RC frame structures, the fiber-reinforced concrete (FRC) was used for the anticipated damage position in this paper. Two frame structures were investigated with nonlinear time history analysis method, in which one is reinforced concrete frame and the other is fiber-reinforced concrete frame. The analysis focuses on the failure mechanism, seismic performance, seismic response and energy dissipation of the frame construction with fiber-reinforced concrete in the anticipated damage position. It is found that the FRC frame has higher deformation capacity, the plastic energy dissipation capacity and small residual deflection. Thus, it can postpone the emergence of the plastic hinges in column, and is conductive to the formation of structural overall failure mechanism. Furthermore, it would benefit the repairation and help reduce the cost .
