摘　　要：为研究探讨钢筋混凝土空腹夹层板楼盖结构的分析方法,在规范规程中实用分析方法-等效刚度法的基础上,本文提出了等效挠度法,并且进行了实际工程中经济技术指标分析。经过理论推导与验证,结果表明:等效挠度法理论依据可靠,验证的空腹梁模型与所等代的实腹梁模型,计算误差均在5%以内,满足工程计算精度要求;大跨度结构中,合理的单元跨度能够保证在挠度相同的情况下,空腹夹层板更加的节约层高和钢筋混凝土用量,对国民经济节约的贡献更大、更加突出。To further study and discuss the analysis method of the floor structure of the reinforced sandwich panel,this paper further proposes the equivalent deflection method based on the practical analysis method-equivalent stiffness method,and analyzes the economic and technical indexes in the actual engineering.After theoretical deduction and verification,the results show that the theory of equivalent deflection method is based on the reliable and validated fast girder model and the equivalent real web girder model,the calculation errors are all within 5%,which meets the engineering requirements.In the long-span structure,the span of the unit can ensure the slab sandwich panel to save more storey and the amount of reinforced concrete under the condition of the same deflection,and make more and more prominent contributions to the national economy.
