通过对140榀混凝土框架的非线性全过程分析,讨论了各种参数对预应力混凝土叠合框架调幅的影响,提出了调幅计算公式,并通过模型试验验证,两者所得的结果较为接近。
Through the analysis of the nonlinear full-scale process of the 140榀 concrete frame, the effects of various parameters on the amplitude modulation of the prestressed concrete composite frame are discussed. The amplitude modulation formula is proposed and verified by the model test. The results obtained by the two are relatively close.
