不同节点型式的装配式方钢管再生混凝土框架结构有限元分析

Finite element analysis of assembled square steel tubular recycled concrete frame structures with different joint types

随着经济、科技的不断发展,装配式结构在建筑中逐渐成为一个重要的结构形式,依据课题组提出的四种不同节点型式的装配式方钢管再生混凝土框架结构抗震性能试验,基于已有理论分析,利用有限元软件ABAQUS进行仿真模拟,对其受力特点、耗能性能进行分析,并研究柱截面尺寸与混凝土强度变化对框架性能的影响。

With the continuous development of economy, science and technology, assembled structure has gradually became an important form of building structure in architecture. Based on the seismic performance tests of assembled square steel tubular recycled concrete frame structures with four different joint types proposed by the research group, based on the existing theoretical basis, the finite element software ABAQUS was used to simulate its mechanical characteristics and energy dissipation. The influence of beam-column size and concrete strength on the performance of frame was analyzed and studied.
