基于SMAF-ECC的装配式自复位框架节点抗震性能
Seismic Performance of Assembled Self-centering Frame Joints Based on SMAF-ECC
摘要
Abstract
Based on the good energy dissipation and self-recovery performance of SMAF-ECC(shape memory alloy fiber-reinforced engineering cementitious composite),an assembled concrete self-cen-tering frame joint based on SMAF-ECC is proposed.On the basis of the material mechanical perform-ance test,ABAQUS was used to simulate the seismic and self-centering performance of the new frame joints,and compared with the frame joints using ordinary concrete and ECC.At the same time,the influence of SMAF content on the seismic performance of the joints was analyzed.The results show that replacing the concrete in the core area of the joint with SMAF-ECC can effectively improve the bearing capacity,energy dissipation capacity and stiffness of the joint,reduce the residual displace-ment of the joint,and improve the self-centering ability of the joint.When the SMAF content is not more than 0.6％,increasing the SMAF content can further improve the self-centering performance and seismic performance of the frame structure.The research results can provide a theoretical basis for the application of SMAF-ECC in assembled concrete frame joints,which is expected to promote its further development in seismic structures.关键词
