摘要:

介绍了带缝钢板剪力墙的屈服承载力、极限承载力、屈曲承载力的理论计算公式,对承载力理论计算公式进行了比较和分析,并在大量的有限元计算结果基础上,得到了确保带缝钢板剪力墙“先塑性后屈曲”的构造措施以及钢板墙外围尺寸和开缝参数的设计建议值。结果表明:考虑材料强化对带缝钢板剪力墙的极限承载力有近10%的提高; 中间壁高度会影响柱状部的塑性发展程度; 竖缝对钢板剪力墙的屈曲荷载有30%～40%的降低影响。

Abstract:

The theoretical calculation formulas of yield capacity, ultimate bearing capacity and buckling capacity of steel plate shear wall with slits(SPWS)were introduced. These theoretical calculation formulas of bearing capacities were compared and analyzed. Based on a lot of finite element calculation results, the detailed constructional measures to ensure “buckling occurring after plasticity” of SPWS were given. The results show that considering material hardening can rise about 10% ultimate bearing capacity of SPWS. The height of middle wall will affect the plastic development degree of SPWS. Vertical slits can decrease 30% to 40% buckling load of steel plate shear walls.
