摘要
采用有限元软件ANSYS,对根据实际工程加固中提出的新型无内隔板节点的极限承载力进行了进一步有限元研究,分析该类矩形钢管柱无内隔板梁柱节点在各加载阶段的位移变化和应力分布情况,考查其破坏形式,并比较了该类节点在不同梁柱截面尺寸下的极限承载力,得到该类节点极限承载力与梁柱尺寸的变化规律,为今后该节点的广泛工程应用提供参考依据。
The ultimate load carrying capacity of a new beam-column joint without inner diaphragm,which is put forward on the basis of a practical project,ls analyzed by finite element program ANSYS. The displacement variation and the distribution of stress of the new beam-column joints at each loading stage are studied. The joint failure mechanism is analyzed. In addition, several examples are calculated to compare the ultimate bearing capacity of joint of different sizes of the beam and column, and the effect of various geometric parameters of the joint on the ultimate strength is discussed. This kind of joints can be used to relating retrofit projects.
