侧筒中间大跨度框架的超限高层结构设计——塔里木油田分公司勘探开发综合楼设计实例

Structure Design of Out-of-Codes Tall Buildings of Side Corewall and Middle Long-span Frame:A Case of Exploration and Development Building of Tarim Oilfield Branch Company

该文结合塔里木油田分公司勘探开发综合楼的结构设计实例,对该大楼的基础及上部结构选型进行了分析,针对上部结构的使用功能及受力特点,平面中部采用钢管混凝土柱,两侧为楼电梯间形成的钢筋混凝土筒体,中间大跨度楼板采用了双向密肋板。根据规范要求,该建筑结构除采用振型分解反应谱法进行地震作用计算外,尚应采用弹性时程分析法进行多遇地震下的补充计算,经计算,结果满足设计要求。另外,该文探讨了钢管混凝土柱基础设计构造、侧筒剪力墙不同布置对结构整体刚度的影响,以及三种不同力学分析软件的结果,提出了相应的解决方法。

Based on structural design example of the exploration and development Building of Tarim Oilfield Company,this paper analysises the foundation and structure type of this tall buildings.Aimed at the features and the mechanical characteristics,the central plane is designed as the steel tubular column,both sides of the elevators as the building of reinforced concrete tube structure,middle Long-span floor plate as a ribbed slab.According to the code,besides the calculation of modal response spectrum method under small earthquake,the building structure should also calculate with elasto-plastic analysis method as a complement.The result meets the code.This paper discusses the foundation design of steel tube concrete column,the effect on the overall stiffness of side corewall structure of the different layout,and the results of three different mechanical analysis software.The corresponding solution is proposed.
