［摘要］多層大跨度公共建筑的混凝土結(jié)構(gòu)體系的關(guān)鍵是樓蓋，傳統(tǒng)的樓蓋做法是混凝土和預(yù)應(yīng)力混凝土框架結(jié)構(gòu)平面力系。在混凝土空腹夾層板結(jié)構(gòu)的基礎(chǔ)上，提出正六邊形平面的多層大跨度混凝土蜂窩型空腹夾層板樓蓋，以滿足公共建筑樓蓋平面形式多樣化的要求。介紹了新結(jié)構(gòu)體系的組成、構(gòu)造、力學(xué)特性，并與傳統(tǒng)結(jié)構(gòu)體系進(jìn)行對(duì)比分析，結(jié)果表明，在正六邊形平面中，新結(jié)構(gòu)的力學(xué)模型為一塊考慮剪切變形的類似圓形平面的夾芯板，其經(jīng)濟(jì)指標(biāo)優(yōu)于傳統(tǒng)結(jié)構(gòu)。

Abstract:The key  of concrete structure system in multilayer long-span public buildings is the floor system. Traditional floor systems are concrete and prestressed concrete structures, which are plane force systems. Based on the  concrete open-web sandwich plate structure, the concrete honeycomb open-web sandwich plate was proposed in order to meet the requirements of the diversification of the flat form of the public buildings. The composition, structure and mechanical properties of the new structure system were introduced, and then compared with the traditional structure system. The results show that in regular hexagon plane, the mechanical model of the new structure is a sandwich plate with similar circular shape considering shear deformation, and its economic index is better than traditional structure.

Keywords:regular hexagon; multistory long-span; floor structure; concrete structure; honeycomb open-web sandwich plate
