基于ABAQUS模拟的速接式轻钢构造柱研究
|
摘要
为研究应用于砌筑填充墙的速接式轻钢构造柱的受力性能及约束能力,以轻钢构造柱与混凝土构造柱的对比试验为基础,利用ABAQUS软件模拟轻钢构造柱填充墙试验,根据模拟得到的墙体损伤云图与试验填充墙裂缝开展比较;并将有限元模拟分析得到的墙体位移、构造柱位移、墙体拉结筋应力与试验结果对比,验证了有限元模型分析的可靠性。经试验及有限元分析表明:轻钢构造柱的整体性好、位移较小,轻钢构造柱与拉结筋连接可靠,能够有效约束住墙体避免墙体倾覆。由于轻钢构造柱施工方便,能有效控制施工质量,故轻钢构造柱替代混凝土构造柱具有良好的应用前景。
In this paper,the mechanical property and confining ability of quick-attachable steel-tie-column,which is applied to masonry fill walls,is studied. On the base of contrast test of steel-tie-column and concretetie-column,ABAQUS software was used to simulate the performance of the test prototype. The comparison between test result and finite element analysis shows that the simulated damage cloud image of the wall agrees well with the test result. By comparing the analysis data,wall displacement,steel-tie-column displacement and the stress of tie bar embed in wall,with the test results,the rationality of finite element model was verified. Test result and finite element analysis show the good of steel-tie-column,such as good integrity,little displacement and reliable connection with tie bar,which makes it available to tie the wall,avoiding wall overturning. Because steel-tie-column is convenient in construction and the construction quality can be effectively controlled,steeltie-column has a good application prospect to replace concrete-tie-column.
