【摘要】:將屈曲約束鋼板墻用于鋼筋混凝土框架結(jié)構(gòu),提出了屈曲約束鋼板墻與混凝土結(jié)構(gòu)的節(jié)點連接構(gòu)造。通過2個單跨兩層模型結(jié)構(gòu)的加載試驗,研究了混凝土框架-屈曲約束鋼板墻結(jié)構(gòu)的抗側(cè)力性能,包括其受力過程、破壞形態(tài)、破壞機制、抗側(cè)剛度、屈服承載力和延性等。研究結(jié)果表明:混凝土框架-屈曲約束鋼板墻結(jié)構(gòu)具有良好的抗側(cè)力性能,屈曲約束鋼板墻有效提高了鋼筋混凝土框架結(jié)構(gòu)的抗側(cè)剛度、屈服承載力、延性和冗余度。利用理論方法計算了結(jié)構(gòu)的抗側(cè)剛度和屈服承載力,其結(jié)果與試驗值基本接近。利用有限元方法對結(jié)構(gòu)的受力過程進行了模擬,與試驗結(jié)果的對比表明所建立的有限元模型及分析方法基本能夠模擬試驗模型的受力情況,可用于該類結(jié)構(gòu)的進一步參數(shù)分析。
[Abstract]:The buckled steel plate wall is applied to reinforced concrete frame structure, and the joint connection between buckled steel plate wall and concrete structure is proposed. Based on the loading tests of two single-span two-story model structures, the lateral force resistance of concrete frame-buckling steel plate wall structures is studied, including the process of loading, failure mode, failure mechanism, lateral stiffness, yield bearing capacity and ductility. The results show that the concrete frame-buckling steel plate wall structure has good lateral force resistance, and buckling steel plate wall can effectively improve the lateral stiffness, yield bearing capacity, ductility and redundancy of reinforced concrete frame structure. The lateral stiffness and yield bearing capacity of the structure are calculated by theoretical method, and the results are close to the experimental values. The finite element method is used to simulate the stress process of the structure. The comparison with the experimental results shows that the established finite element model and the analysis method can basically simulate the stress of the test model and can be used for the further parameter analysis of this kind of structure.
