【摘要】 中国禄丰侏罗纪世界遗址馆主厅为高烈度区不规则大跨结构。在结构设计中采用钢网架-框架柱-巨型柱(核心筒)结构体系,通过结构整体建模分析了地震力影响。考虑地震荷载引起的弯矩和轴力增加,采用加强核心筒、增强核心筒与钢网架连接、设置周边橡胶支座等措施,解决不规则结构抗震和超长问题,达到了建筑形体和结构体系的和谐统一。更多还原

【Abstract】 The Exhibition Hall of Jurassic World in Lufeng is an irregular and large-span structure in highly seismic region.Steel grid-concrete frame column-concrete giant column (core tube) structure is adopted and the seismic action of integral structural is analyzed.Considering the increment of moments and axial force of column,special structural methods,such as strengthening the core tube,strengthening the connection of core tube and grid structure,adopting the rubber plinth,are applied to meet the seismic and over-length requirements.更多还原
