[摘要]北京炼焦化工厂能源研发科技中心1号楼存在扭转不规则、偏心布置、凹凸不规则、楼板不连续等不规则项,采用设置结构缝、滑动支座等方法将1号楼地上结构合理划分为各自独立的单体,有效避免了结构多项超限不规则;通过对多个方案进行分析比较,确定了为中庭C区索网幕墙提供支承的巨型框架的构件布置形式;介绍了屋面大跨装饰架和悬挑装饰架的结构体系和支座形式;并对其进行考虑双非线性的整体稳定分析和抗连续倒塌分析。分析结果表明,装饰架结构稳定承载力安全系数不小于2-0;悬挑装饰架任一受拉支座失效,不会引起其余结构构件的连续失效。

[关键词]结构缝; 滑动支座; 巨型框架构件布置; 位移限值; 抗连续倒塌

Abstract:The No. 1 Building of Energy Research and Development Technology Center of Beijing Coking Chemical Plant has irregularities such as torsion irregularity, eccentric arrangement, irregular irregularities and discontinuous floor slabs. The structure of the No. 1 building was reasonably divided into separated structures by using the structural joints and sliding supports, which effectively avoids multiple irregularities in the structure. Through the analysis and comparison of several schemes, the component arrangement form of the mega frame which provides support for the cable curtain wall of the atrium C area was determined; the structural system and the support form of the large-span decorative frame of the roof and the cantilever decorative frame were introduced; overall stability analysis and the progressive collapse resistance analysis considering double nonlinearity were conducted. The analysis results show that the safety factor of the stable bearing capacity of the decorative frame structure is not less than 2-0; the failure of any one of the cantilevered decorative frame will not cause continuous failure of the remaining structural components.

Keywords:structural joint; sliding support; mega frame component arrangement; displacement limit; progressive collapse resistance
