摘　　要：磷石膏模壳空腹楼盖不仅具有良好的受力性能和保温性能,而且楼盖结构高度低、结构规整,使其在工程中得以广泛应用。目前对空腹楼盖的研究主要侧重于静力分析,在动力荷载下性能往往被忽视,空腹楼盖模态分析能够反映出楼盖因不同的挖空方式造成的动力特性差异,弥补静力力分析的不足。以两类新型空腹楼盖结构为例,通过理论介绍、软件建模分析,分析对比了两类楼盖的动力特性。Phosphorus gypsum embedded filler cast-in-place concrete hollow floor not only has good mechanical properties and thermal insulation performance,but also has low structure height and neat appearance,therefore is widely used in engineering projects. At present,researches of the hollow floor mainly focus on static analysis,and its performance under dynamic load is often neglected. Modal analysis can reflect the difference in dynamic characteristics caused by different hollowing patterns,and can make up for the disadvantages of static analysis. Through theoretical introduction and software simulation,we analyzed and compared the dynamic characteristics two kinds of new-type hollow floor.
