摘要: 青州博物館新館是一座國家一級綜合性博物館,具有獨特的建筑立面造型和復(fù)雜的平面功能布局,且結(jié)構(gòu)平面及豎向布置不規(guī)則。 結(jié)合建筑特點,闡述了結(jié)構(gòu)設(shè)計的難點。 基于整體模型計算結(jié)果,分析比較了兩種主體結(jié)構(gòu)體系,最終采用了鋼筋混凝土框架-剪力墻結(jié)構(gòu),并對其進行了小震彈性和大震動力彈塑性時程分析。 通過綜合比較中庭上方大跨度樓蓋兩種結(jié)構(gòu)形式的優(yōu)缺點,選擇了雙向平面鋼桁架梁+鋼筋桁架樓承板樓蓋,并對其進行了豎向地震作用分析。 對于長懸挑外檐結(jié)構(gòu)設(shè)計、結(jié)構(gòu)體型收進以及樓板錯層,提供了相應(yīng)的解決方案。 針對超長混凝土結(jié)構(gòu)的溫度和收縮裂縫控制進行了分析,給出了一些設(shè)計和施工措施。 結(jié)果表明:結(jié)構(gòu)受力合理、傳力明確,實現(xiàn)了結(jié)構(gòu)安全和建筑創(chuàng)意的完美融合。

Abstract: The new Qingzhou Museum is a national first-class comprehensive museum with unique building facade shape and complex plane function layout, and the structural plane and vertical layout are irregular. Combined with the architectural characteristics, the difficulties in structural design were introduced. Based on the calculation results of the overall model, the two main structural systems were analyzed and compared. The reinforced concrete frame-shear wall structure was finally adopted, and the elastic time history analysis of frequent earthquakes and dynamic elastic-plastic time history analysis of rare earthquake were carried out. By comprehensively comparing the advantages and disadvantages of two structural types of long-span floor above the atrium, the floor system of the two-way plane steel truss+steel-bars truss deck was selected, and the vertical seismic action analysis was carried out. The corresponding solutions were provided for the structural design of long cantilevered outer eaves, the retraction of structural shape and the staggered floor. The temperature and shrinkage crack control of super long concrete structure were analyzed, and some design and construction measures were given. The results show that the structural force is reasonable and the force transmission is clear, realizing the perfectintegration of structural safety and architectural creativity.
