摘　　要：西交利物浦大学影视学院结构形式为下小上大,下部主体为三层钢筋混凝土框架结构,为满足建筑平面功能的要求,采用不等距柱网,设有穿层柱、独立悬臂柱、V型柱,落地点基础采用高强预应力管桩抗水平力;上部钢屋盖平面形状为新颖独特的三角形自由面,采用单层网壳结构,整体屋盖通过11根钢柱和两个落地点支承,其中8根钢柱落在下部混凝土结构框架柱上,3根为独立悬臂柱,西侧屋面悬挑15 m。下部混凝土结构通过SATWE和PMSAP软件计算,上部钢屋盖采用SOFISTIK和SAP2000软件计算,整体模型采用SAP2000软件计算。结果表明,结构的整体指标和承载力满足规范要求,关键构件按中震弹性的性能化设计,确保了结构安全,可供类似的工程设计参考。The structure of the School of Film and Television of XJTLU is small at the bottom and large at the top,and the main body of the lower part is a three-layer reinforced concrete frame structure.In order to meet the requirements of the building plane function,the unequal distance column network is adopted,with cross-layer columns,independent cantilever columns,V-shaped columns,and high-strength prestressed pipe pile is adopted for the foundation of the falling site to resist horizontal force.The plane shape of the upper steel roof is a unique triangular free plane,which adopts a single-layer lattice shell structure.The overall roof is supported by 11 steel columns and two landing points,among which 8 steel columns fall on the lower concrete frame columns and 3 independent cantilever columns.The west roof is overhung by 15 meters.The lower concrete structure was calculated by SATWE and PMSAP software,the upper steel roof was calculated by SOFISTIK and SAP2000 software,and the overall model was calculated by SAP2000 software.The results show that the overall index and bearing capacity of the structure meet the requirements of the code,and the key components are designed according to the performance of the earthquake elasticity to ensure the safety of the structure,which can be used as a reference for similar engineering design.
