摘　　要：针对某演艺中心楼板开大洞的结构不规则性特点,分别假定开大洞楼板为刚性楼板和弹性楼板,并运用PKPM分析软件,分析了楼板开大洞对结构的影响,计算结果表明,不同的楼盖计算类型对结构的周期、周期比和剪重比影响不明显,而对结构的内力、层间位移角和位移比有显著影响,指出在分析楼板开大洞的结构时,应考虑楼板的面内变形对结构受力的影响,在内力分析时,开大洞楼板宜按弹性楼板考虑。According to the structure irregular features of an arts center floor opening,respectively assuming floor opening without rigid floor and elastic floor,and using PKPM analysis software,analyzed the influence of floor opening to structure,the calculation results showed that,different floor calculation types had no obvious effect on structure cycle,cycle ratio and shear weight ratio,but had significant effect on structure internal force,interlayer displacement angle and displacement ratio,pointed out that in analyzing the floor opening structure,should thinking the influence of floor slab in-plane displacement to structure stress,in the analysis on internal force,the floor opening floor should be considered according to the elastic floor.

关 键 词：楼板开大洞 刚性楼板 弹性楼板 内力分析
