基于ABAQUS砌体结构水平嵌筋加固动力分析

Dynamic Elastic-plastic Time-history Analysis of Horizontal Reinforcing Bars Embedded in Masonry Structure Based on ABAQUS

传统村落建筑是中华传统文化的重要载体,然而对传统砌体结构加固更加注重建筑历史和风貌的保护,本文基于配筋砌体的思想提出水平嵌筋加固方法对砌体结构加固;利用ABAQUS中混凝土损伤塑性模型对太行山区传统砌体结构进行水平嵌筋加固弹塑性动力分析,具体分析主要水平嵌筋间距对砌体结构加固效果的影响。结果表明嵌筋间距越小,结构层间位移较越小,加固效果越好,嵌筋间距在150~300mm较为加固效果较为合理。

Traditional village architecture is an important carrier of traditional Chinese culture,however,the preservation of traditional masonry structure is more emphasis on architectural history and features.Based on the idea of reinforced masonry,the method of horizontal reinforcing bars embedded in masonry structure is put forward to reinforce masonry structure.The elastic-plastic dynamic analysis of horizontal reinforcing bars embedded in the traditional masonry structure in Taihang mountain area is carried out based on the plastic model of concrete damage in ABAQUS.The influence of horizontal spacing of reinforcement on masonry structure is analyzed.The smaller the spacing of the reinforcement is,the smaller the displacement Angle between the structural layers is and the better the reinforcement effect is.From the above analysis,it can be seen that the spacing of the embedded bars is more reasonable at 150~300mm.
