摘要

摘要: 采用開源地震工程模擬系統（OpenSees）對以正交膠合木作填充墻的鋼框架結構進行探索性數值研究，主要研究該填充墻鋼框架單元在單調和循環加載作用下的受力性能，墻體與鋼框架之間的協同工作性能以及連接個數對整體結構受力性能的影響.結果表明：正交膠合木填充墻能夠提高鋼框架的抗側剛度和水平承載力；柔性連接的設置使整體結構耗能性能良好；工作縫的設置減緩墻體的開裂，更大程度上發揮連接件的耗能和變形能力；連接個數對構件的抗側能力影響較大，可以通過調整連接數量和連接間距設計出具有多種剛度和耗能能力的框架單元.

Abstract: Open System for Earthquake Engineering Simulation (Abbrev. OpenSees) was used to do some exploratory numerical research on the cross laminated timber (CLT) infill wall-steel frame system. Numerical analysis was performed including the mechanical performance of the CLT infill wall-steel frame under monotonic and cyclic loading, cooperative working performance between the CLT panel and steel frame, and the influence of the number of bracket connections on the mechanical performance of the structure. The results are presented as follows:the lateral stiffness and bearing capacity of the steel frame can be strengthened by the CLT infill wall; flexible connections show a better performance of energy dissipation; the gap setting is not only used to postpone the cracking time of the wall, but also beneficial to develop the energy dissipation and deformation of connections; the number of connections has great effect on the lateral resistance of the structure, and furthermore, various stiffness and energy dissipation capacities of the structure can be designed by adjusting the number and space of connections.
