数字北京大厦结构设计及其关键问题

数字北京大厦为双塔结构，中部地下层1—4为共享大厅。建筑总长度为137m，在层11双塔之间设连廊。介绍主体结构方案的确定，线性及非线性分析，单跨框架一剪力墙结构在剪力墙间距较大时的计算及构造处理，超长结构不设伸缩缝处理，局部连接薄弱处的加强处理，连廊的抗震支座及共享大厅钢架的设计等问题，供同类设计参考。

The Continuum Analytical Method of Steel Frame- Reinforced Concrete Shear Wall Mixed Structure

The inter-story drift stiffness considered the semirigidity of beam and column joints connection, and P-Delta second order effect of steel frame parts in the mixed structure is presented in the paper. After considering on the influence of semirigidity between steel beams and steel columns, second order effect of beam-column members for steel frame and structural second order effect, the traditional continuum analytial method used in RC shear-frames wall structure is developed to steel frames-reinforced concrete shear wall mixed structure subject to horizontal load in this paper. A continuum approach, which is suitable for analyzing steel frames-reinforced concrete shear wall mixed structure subject to horizontal load, is presented. The method is relatively simple and more practical. It will be referred to structural design for steel frames-reinforced concrete shear wall mixed structure.

玉兰大剧院主体结构设计与分析

东莞玉兰大剧院主体结构的设计包括结构体系选择、抗震设计分析、复杂结构设计处理。计算分析表明,框架-剪力墙结构适用于大空间复杂结构,主体结构较好的整体动力与变形性能。设计中基础采用了预应力管桩、人工挖孔桩和抗浮锚杆,主体结构采用斜柱的剪力墙体系,裙房和屋面采用钢结构。通过精心设计,工程交付使用后,结构的工作状态良好。
