变电站格构式钢构架螺栓连接的有限元分析

Analysis of Steel Framework Bolt Connect FEA in Substation

变电站经常采用全联合格构式钢构架,钢柱和钢梁均采用螺栓连接。由于格构式钢构架螺栓连接的节点直接影响整个结构安全,所以螺栓连接的受力在钢构架设计中十分重要。采用ABAQUS软件对螺栓连接节点进行建模和有限元分析,为变电站格构式钢构架螺栓连接设计提供理论支持。

The lattice angle steel full joint frameworks are frequently used in the new substation,which is joined by the lattice steel columns and steel beams.The security of the steel structure node affects the safety of the whole structure directly.The bolted stress analysis is a very important part in the transformation truss design.The nodes connected analysis is discussed in order to provide a theoretical basis for engineering joint framework bolted joint design by using ABAQUS modeling and finite element analysis.
