装配式空心混凝土剪力墙抗震性能有限元模拟

FINITE ELEMENT SIMULATION ON SEISMIC PERFORMANCE OF PREFABRICATED HOLLOW CONCRETE SHEAR WALL

装配式建筑成为现在建筑行业的趋势,同时为了满足节能以及减轻自重的需求,本文研究装配式空心混凝土剪力墙的抗震性能。共采用4个不同构造的剪力墙有限元模型,第一组是都有后浇边缘构件的实心混凝土剪力墙和空心混凝土剪力墙,第二组是普通实心混凝土剪力墙和在构件边缘有孔洞的空心混凝土剪力墙,用ABAQUS软件进行有限元分析。结果表明,空心混凝土剪力墙不仅可以满足抗震性能要求,还可以节省材料。

Prefabricated buildings have become the trend of the construction industry. In order to meet the needs of energy saving and self-weight reduction simultaneously, this paper has studied the seismic performance of fabricated hollow concrete shear walls. A total of four finite element models of shear walls with different structures have been used. The first group is a solid concrete shear wall with post-pouring edge members and a hollow concrete shear wall. The second group is a common solid concrete shear wall and a hollow concrete shear wall with holes at the edge of the component. Finite element analysis was conducted with ABAQUS. Results show that the hollow concrete shear wall can not only meet the requirement of seismic performance,but also can save material.
