本文以“钢筋混凝土抗震结构的机构控制理论”为指导,对钢筋混凝土双肢剪力墙进行试验研究及理论分析,论证了“机构控制理论”对钢筋混凝土剪力墙结构的可行性。文章还编制了对双肢剪力墙进行弹塑性全过程分析的电算程序,并将计算结果同试验相比较,两者结果符合较好,验证了程序的可靠性。还利用电算程序对一个18层双肢剪力墙结构进行了抗震设计,通过调节连系粱的塑性弯矩值,分析各种调幅方案,找出了其最佳耗能形式。最后,文章根据试验及理论分析,对延性双肢墙结构的工程设计提出了建议及最佳耗能机构的控制实施条件。
Based on the theory of mechanism control of reinforced concrete anti-earthquake structure, this paper conducts experimental research and theoretical analysis on reinforced concrete double-limb shear wall, and demonstrates the feasibility of “institutional control theory” on reinforced concrete shear wall structure. The paper also compiles the computer program for the elastoplastic whole process analysis of the double-limb shear wall, and compares the calculated results with the test. Both results are in good agreement and verify the reliability of the program. An anti-seismic design of an 18-story double-limb shear wall structure was also performed using a computer program. By adjusting the plastic bending moment values of the connecting jaws, various amplitude modulation schemes were analyzed to find out the best energy dissipation form. Finally, based on experiments and theoretical analysis, the article puts forward suggestions for the engineering design of ductile double-limb wall structures and the conditions for the implementation of optimal energy-consuming mechanisms.
