［摘要］廣西文化藝術(shù)中心由三個單體組成，每個單體呈山的造型，由內(nèi)部的混凝土結(jié)構(gòu)和外圍的拱形鋼屋蓋組成。三個鋼屋蓋通過外圍的雨篷桁架連為一體，與混凝土結(jié)構(gòu)設(shè)防震縫脫開。混凝土部分嵌固在基礎(chǔ)底板，通過地下室連為一體，為大底盤多塔結(jié)構(gòu)。拱形鋼屋蓋落在大底盤頂面的混凝土環(huán)梁上，混凝土部分與鋼結(jié)構(gòu)部分獨立計算。介紹了基礎(chǔ)設(shè)計及體系布置，詳細(xì)闡述了大底盤多塔結(jié)構(gòu)的設(shè)計方法及混凝土環(huán)梁的比選設(shè)計思路，考慮了上部鋼結(jié)構(gòu)與下部混凝土結(jié)構(gòu)的相互影響，對鋼屋蓋關(guān)鍵節(jié)點采用有限元軟件ANSYS進(jìn)行計算分析，結(jié)果表明，結(jié)構(gòu)設(shè)計合理可行。

Abstract:Guangxi Culture and Art Center is composed of three single buildings, each of which is shaped like a mountain. It is composed of an internal concrete structure and an arched steel roof. The three steel roofs are connected by the outer canopy truss and are separated from the concrete structure with seismic joints. The concrete part is embedded in the foundation slab and connected with the basement into a whole, which is the multi tower structure with enlarged baseplate. The arched steel roof is connected to the concrete ring beam on the top of the enlarged baseplate, and the concrete part and steel structure part are calculated independently. The foundation design and structural system layout were introduced. The design method of multi tower with enlarged baseplate and the comparison and design idea of different concrete ring beam schemes were described in detail. Considering the interaction between the upper steel structure and the lower concrete structure, the finite element software ANSYS was used to calculate and analyze the key joints of the steel roof. The results show that the structural design is reasonable and feasible.
Keywords:Guangxi Culture and Art Center; theater architecture; multi tower with enlarged baseplate; ring beam; large-span spacious structure; large-span steel roof
