钢框架-内填充墙结构设计方法的分析与建议

ANALYSIS AND SUGGESTION TO THE DESIGN APPROACHES OF STEEL FRAMES-INFILLED WALL

钢框架-内填充墙结构作为抗侧力体系。利用钢筋混凝土剪力墙剪切刚度较大的特点来分担更多的剪力，但由于其缺少足够的理论和试验研究依据，实际工程中应用较少。重点介绍钢框架-内填充墙结构的设计方法，进行了相关的对比分析，最后对此结构的设计、分析方法提出建议：认为钢框架承受全部设计重力荷载，由抗剪连接件及剪力墙承担全部横向荷载；此结构的破坏模式、计算假定等还需通过更多的有限元数值模拟及试验加以进一步验证。

The steel frame-reinforced concrete infill wall system （SRCW） acts as the lateral load resisting systems in buidings, utilizing the high shear stiffness of the RC infill wall to attract most shear forces. This system is rarely used in practice due to lack of sufficient evidence in theory and experiment research. The design methods of SRCW are introduced. Analyses and comparison of these methods are carried out. At last, the design and analysis suggestions should be attentions. It is assumed that the bare steel frame shall have the capacity to resist 100 percent of the design gravity load, the reinforced concrete infill wall and the shear stud shall have the ability to resist 100 percent of the design lateral force. The failure modes and the calculated assumption should be verified by finite element analysis and test results.
