两边连接双层钢板剪力墙承载力性能研究

The bearing capacity performance of two-side connected steel-plate-steel shear wall

采用有限元软件ANSYS对上端简支、下端固定的双层钢板剪力墙进行静力荷载作用下的分析,研究了钢板厚度、混凝土厚度、跨高比、螺栓间距等因素对极限承载力的影响。结果表明,适当的混凝土板厚度,能有效的阻止钢板的侧向屈曲,对提高剪力墙的极限承载力存在有利影响;钢板的极限承载力随钢板厚度和跨高比的增大而增高,随螺栓间距的增大而降低,选取合适的材料厚度和尺寸对双钢板剪力墙在结构中的应用有重要的意义。

The static loads analysis of upper simply supported and the lower fixed double steel wall were carried out by using the finite element software ANSYS.The effect of the plate thickness,the thickness of concrete,cross-height ratio,the bolt spacing and other factors on ultimate bearing capacity were studied.Results indicated that appropriate thickness of the concrete slab can prevented effectively the lateral plate from buckling and had the beneficial effects on the ultimate strength of shear wall ; Ultimate bearing capacity of steel plate increased with increasing of thickness and cross-height ratio but decreased with spaces increasing between bolt.It was significant to select the appropriate material thickness and dimensions for the application of the double steel plate shear walls.
