灾难性荷载作用下钢结构承载力损伤的数值模拟

Numerical Simulation for Strength Damage of Steel Structures Subjected to Disastrous Loadings

在灾难性的短期荷载作用下，结构构件以至结构整体承载力下降，称为强度退化．文中建立了一种能够模拟钢框架构件及其结构强度退化的数值分析方法，与多种试验结果的比较表明该方法是可靠的．

Loading capacity of structural members or structures will deterorate due to the action of disastrous loadings. It is called strength degradation. In this paper,a numerical analysis model is established to simulate the strength degradation of steel frame structures and its members. The reliability of this model is shown by comparison with the test results.
