［摘要］大连恒隆广场形如“双鱼”，平面尺寸超长，场地地形高差较大，存在大型中庭及电影院以致开洞较多，部分区域有钢结构斜面屋顶，部分柱需作转换，存在竖向抗侧力构件不连续的情况。主要介绍超长结构设计的关键问题，包括超长结构混凝土的温度应力分析、结构转换、跃层柱、大跨及长悬臂梁、带高差的钢桁架结构体系等问题。通过

对结构在罕遇地震下的非线性分析，对整体结构的抗震性能进行评价。

［关键词］超长结构； 少墙框架\|剪力墙结构； 结构转换； 带高差的钢桁架

Abstract:Dalian Henglong Square shapes like ″Pisces″ with superlong plane size and large elevation difference in site. The existence of large atrium and cinemas leads to many structural openings. Steel structure oblique roof exists in some areas. Parts of columns need to be converted, leading to the discontinuity of vertical lateralresisting members. The key problems in superlong structural design were mainly introduced, including temperature stress analysis of superlong concrete structure, structural transfer, skipfloor column, largespan and longcantilever  beam and steel truss structural system with elevation difference. The nonlinear analysis of the structure was carried out under  rare earthquake  to evaluate the seismic performance of the overall structure.

Keywords:superlong structure； frameshearwall structure with limited shear wall； structural transfer； steel truss with elevation difference
