摘　　要：根据板柱节点受冲切承载力的要求,现浇混凝土空心板-柱结构常需配置柱帽或托板。托板的配置使得等代梁刚度有所增大,为此针对配置托板的特点,根据力法基本原理,给出托板对等代梁抗弯刚度和固端弯矩的调整系数,并编制相关的表格。以某多层办公楼为算例说明了相关公式及图表的应用。Drop-panels and column caps are often disposed in cast-in-situ concrete hollow-slab column structures for the requirements of punching shear resistant capacity of slab-column joints. The drop-panel-equipped joints factors for adjusting the bending stiffness and fixed-end bending moment due to the existence of drop-panels are deduced according to the fundamental of Force Method. Related tables are also presented as references for designers. A calculation example of a multi-floor building is given to show the applications of these formulas and tables.
