[摘要]  本文以某鋼結(jié)構(gòu)辦公樓為案例，對(duì)采用壓型鋼板混凝土組合樓蓋與采用木樓蓋兩種樓蓋方案，從結(jié)構(gòu)設(shè)計(jì)方法、工程量、施工進(jìn)度等方面都做了一系列的比較。結(jié)果表明：采用木樓蓋有效降低了結(jié)構(gòu)自重，從而大大減小了結(jié)構(gòu)水平地震力作用；降低基礎(chǔ)受力，減少基礎(chǔ)造價(jià)；減小梁柱截面，降低用鋼量；輕型木樓蓋滿足裝配化施工，擺脫了濕作業(yè)，大大提高了施工速度。

Abstract: In this paper, a design case of a multi-storey steel office building, which applied two different plan of floor system, the profiled sheeting-concrete composite slabs and the light wood diaphragms, is raised to making comparisons in the fields of design method, total amount of engineering and construction speed. Results show that, the light wood diaphragm plan leads to a large reduction of the structure self-weight, which caused a corresponding cut down of the horizontal seismic force. Meanwhile, the cost of foundation, the column & beam sections and the amount of steel are also lowered down. By the prefabricated construction, wood diaphragm plan also dramatically improves the construction schedule.

Keywords: steel frame; profiled sheeting-concrete composite slab; light wood diaphragm; horizontal seismic force
