[摘要] 介紹了現(xiàn)澆空心板樓蓋應(yīng)用于大柱網(wǎng)、大荷載倉(cāng)儲(chǔ)及廠房結(jié)構(gòu)的設(shè)計(jì)實(shí)例。根據(jù)板式樓蓋的受力特點(diǎn)，確定合理的結(jié)構(gòu)布置方式。采用細(xì)分板單元模型進(jìn)行精細(xì)化分析，根據(jù)其應(yīng)力分布規(guī)律，優(yōu)化了結(jié)構(gòu)布置，采取合適的配筋方式及構(gòu)造措施。通過(guò)幾個(gè)實(shí)際工程的對(duì)比分析，空心板樓蓋在大跨度、大荷載結(jié)構(gòu)中，比梁板式樓蓋更為經(jīng)濟(jì)有效。本文還對(duì)現(xiàn)有規(guī)程的一些規(guī)定進(jìn)行了討論。

Abstract: Hollow flat slab structure is one of the structure forms suitable for large span and heavy load. Several examples show that hollow flat slab structure can get better applicability and better economy than beam-column structure. Those examples had been designed using finite element analysis method. According to the stress distribution of the hollow flat slab, the structurallayout and reinforcement layout had been optimized, which can make sure of security and economy. In addition, some provisions of the tecluucal codes have been discussed.
Keywords: hollow slab; flat slab; industrial buildings; warehouse; optimization design; structural measures
