摘要
苏州太仓阿尔卑斯雪世界结构形式为钢筋混凝土框架结构,屋盖采用平面桁架体系.存在扭转不规则、楼板不连续、偏心率大于 0.15、错层等不规则项,为超限高层建筑.对基础形式、结构体系、荷载取值、性能目标等进行了介绍,并采用YJK、PMSAP、MIDAS Gen三种软件进行了弹性计算,应用Paco-Sap软件进行动力弹塑性分析;阐述了雪场结构设计中的关键问题,如层间位移角、长短柱、桁架关键节点、温度荷载等.计算结果表明,结构的周期比、层间位移角等指标均满足规范要求.采用性能化设计和动力弹塑性分析方法实现结构和构件在中震和大震作用下的既定性能目标,并对结构关键部位和构件采取了针对性的加强措施.
Abstract
The structural system of Suzhou Taicang Alps Snow World is reinforced concrete frame structure,and a plane truss system is used for the roof.Out-of-code properties such as torsional irregularity,inconsistent slab,eccentricity ratio greater than 0.15 and split-level exists in the structure,thus the building is an out-of-code high-rise building.The foundation form,the structural system,the load evaluation,and the performance goal of the structure were introduced.Elastic calculation was performed by using three different programs YJK,PMSAP and MIDAS Gen.Paco-Sap was also used to carry out the dynamic elastoplastic analysis.The key problems in ski area structural design was stated,such as story drift ratio,long and short columns,key joints of the truss structure and temperature load.The calculation results show that the indicators such as the period ratio and the story drift ratio all meet the requirement of standard requirements.By carrying out performance-based design and dynamic elastoplastic analysis,the designed structure and its components are able to satisfy the stated performance goal under moderate and rare earthquakes.Strengthening measures were also adopted targeting critical areas and key components.
