摘　　要：传统建筑结构中现浇混凝土不仅污染环境、制造噪声,还增加了工人的劳动强度,且难以保证工程质量。通过对结构选型,以叠合梁配合密肋楼板工程为例,分析了先张法预应力混凝土叠合式受弯构件计算的基本原理及其在建筑结构中的应用。工程实施情况表明:应用此种叠合梁配合密肋楼板的结构体系具有造价低、梁高小、跨度大、施工速度快和抗震性能好等诸多优势。The traditional architectural structures a lot of concrete is the scene of casting, not only the pollution of the environment, making noise, but also increased the labor intensity, and at the same time, to guarantee the quality of the project. This article through to the structural type for composite beams with dense rib of the floor of the engineering example, the author introduces a method first prestressed concrete composite type flexural members of the calculation principle and structure of the building in the application. From the implementation of the project ultimately situation, this kind of composite beams with application of multi-ribbed slab structure system has low cost, high beam, span, construction speed is quick, seismic oerformano~ i~ n.v, nd ~,-,A - a
