【弹塑性分析笔记】 ABAQUS弹塑性楼板损伤结果解读

结构弹塑性分析可以较好地反映结构的薄弱部位。大震弹塑性分析和小震设计、中大震拟静力分析具有一定的可比性。如图是YJK的拟静力楼板应力分析结果及ABAQUS大震分析的损伤结果,弹塑性分析反映了结构的薄弱部位。

ABAQUS超高层结构大震弹塑性时程分析笔记

ABAQUS 做整体分析比较花时间,计算也需要花很多时间,因此,每个过程均需要十分细心,因为错了从来时间成本太大。 不管是前处理建模,还是后处理分析,还有超限文本撰写,都应该是建立在对结构理解的基础上,不能论文一个操作员,能简化,能提高效率的地方就要提高效率,尽量把更多时间用在把握和理解结构机理、结构特性、建立结构概念基础上。

[书]PERFORM-3D原理与实例 – 第7章 – 填充墙模拟

在传统的结构分析中,填充墙通常作为非结构构件考虑,在分析过程中,将其以外荷载的形式施加到结构上,并对整体结构的周期进行折减以考虑填充墙对结构刚度的贡献,未直接考虑填充墙对结构非线性行为的影响。相关研究表明[1,2],填充墙对结构的抗震性能有着重要的影响,在结构弹塑性分析中,应合理考虑填充墙的影响。本章首先对砌体填充墙的抗震性能及填充墙的数值模型进行介绍,并着重介绍了基于等效斜压杆的填充墙宏观模型的参数计算方法,最后采用PERFORM-3D[3,4]对一单跨框架填充墙结构的低周往复加载试验进行模拟,讲解PERORM-3D中采用等效斜压杆填充墙模型进行框架填充墙模拟的基本步骤与参数设置方法。In traditional structural analysis, infilled wall is usually considered as non-structural element, and its effect to structure performance was only considered by applying equivalent external load to the main structure and reducing the structure period, the contribution of infilled wall to the structural nonlinear behaviour was not considered directly. Relevant studies have shown that infilled wall has significant influence on both linear and nonlinear structural performance. Therefore, infilled wall should be reasonably considered in structural elasto-plastic analysis. In this chapter, the seismic performance and numerical model of masonry infilled wall was firstly introduced, and the parameters calculation method of the macroscopic infilled wall model based on equivalent diagonal strut theory was explained in detail. After that, a PERFORM-3D simulation of low-cyclic reversed load test of a single span infilled frame structure was conducted by step by step, to explain the fundamental modelling process and parameter definition method of the equivalent diagonal strut infilled wall model.
