考虑累积损伤的钢结构楼层地震损伤因子计算的Python语言实现

Analysis of Seismic Damage of Body-shaped Retracted Structures based on Python Language

钢结构在罕遇地震作用下会进入非线性状态,导致结构的某些部位发生相应的损伤,结构的刚度、强度等力学性能也会相应的降低。这种力学性能的降低将直接影响结构的动力特性,从而降低结构的抗震性能。为了合理评价钢框架结构的地震损伤,运用相关结构分析软件设计了几种不同高度的钢框架模型,分析了其在不同地震波作用下的累积塑性应变,采用Python语言快速提取损伤数据。探讨了结构关键层构件的累积塑性分布,评估结构在地震作用下的损伤指标。

Steel structures will enter a non-linear state under the action of rare earthquakes,causing corresponding damage to certain parts of the structure,and the mechanical properties of the structure such as stiffness and strength will also be correspondingly reduced.This reduction in mechanical properties will directly affect the dynamic characteristics of the structure and thus reduce the seismic performance of the structure.In order to reasonably evaluate the seismic damage of the steel frame structure,several steel frame models of different heights were designed using relevant structural analysis software,and their cumulative plastic strains under different seismic waves were analyzed.The Python language was used to quickly extract the damage data.The cumulative plastic distribution of the key layer members of the structure is discussed,and the damage index of the structure under the earthquake action is evaluated.
