摘要

为研究大型火电厂主厂房钢框架异型节点的受力性能，以轴压比及柱两侧梁截面高度比为设计参数，制作了6个缩尺比为1:4的异型节点试件，对其进行了低周反复加载试验。基于试件破坏规律分析了影响节点域承载能力的主要因素，通过对节点域进行分区并依据力学原理推导了该类型节点域的设计计算公式，将计算结果与试验结果进行比较，两者差值在18%左右，表明论文所提出的刚性钢框架异型节点域的设计方法是可行的，对节点域的设计计算有助于保证强节点要求。

Abstract

In order to study the mechanical behaviors of irregular joints in rigid steel frames which had been used in largescale power plant

6 specimens in 1/4 scale of the prototype model were designed according to different axial compression ratio and section height ratio of beams and were tested under low cyclic reversed loading.Based on the failure law of specimens

the main factors that affect the bearing capacity of the irregular joints were analyzed.By the division of panel zone

the calculating formula was put forward according to mechanical principles.It is found that the difference between calculating results and experimental results is about 18%.And the proposed method for calculating the irregular joints in rigid steel frames is feasible.
