钢板件考虑损伤的滞回性能分析

A Cyclic Analysis on Steel Plates with Damage

在结构钢弹塑性各向异性损伤本构模型的基础上，采用U.L.格式的壳体大挠度双重非 线性有限元分析方法，对四边简支板件进行面内拉压循环荷载作用下的滞回性能分析，结合 GBJ17-88塑性设计中对箱型截面翼缘宽厚比限值的规定，提出新的建议.

Based on the constitutive relation model of constructional steel with elasto- plastic anisotropic damage, the authors analyzed the hysteretic characte ristics of steel plates with four sides pinned by way of double nonlinear shell FEM, and advanced proposals on the width-thickness ratio of the steel plates reg ulated in GBJ17-88.
