摘　　要：以国内某换流站阀厅的新型嵌入式装配式防火墙混合结构为研究对象,建立了有限元精细化实体模型和等效多杆斜撑模型。基于现有的等效单杆斜撑有效宽度计算公式,进行有限元分析模拟与数值拟合,探究适用于该文研究的框架-嵌入式装配防火墙结构体系的等效多杆斜撑模型有效宽度的计算公式,并选取部分影响因素进行探讨。结果表明:建立的等效多杆斜撑模型有效宽度的计算公式是合理的,并适用于不同跨高比、轴压比、墙板块数及墙板厚度。The finite element refined solid model and the equivalent multi strut simplified model of the frameworkembedded assembly firewall structure were established.Based on the existing effective width calculation formula of the equivalent single strut simplified model,the effective width calculation formula of the equivalent multi strut simplified model of the framework-embedded assembly firewall structure was explored by the finite element analysis and numerical fitting,and some influence factors were discussed.The results show that the formula for calculating the effective width of the model is reasonable,and it is suitable for different span height ratio,axial compression ratio,number of blocks and wall thickness.
