【摘要】 在甬江实验室集聚区2号科研楼中,底部为高大空间,一层和标准层的层高比值达到3倍以上。为避免出现薄弱层,地上对混凝土框架结构、框架-剪力墙结构、框架-钢支撑结构三种方案进行了比选,选择了框架-钢支撑的结构方案。钢支撑的平面和立面布置,按结构受力和建筑功能要求协调一致,并进行了节点分析和设计。基础设计中,一层地坪结构根据使用方要求进行了针对性设计,采用了地坪结构板+桩基的结构方案,可以满足重载、隔绝振动、减少沉降等要求。更多还原

【Abstract】 In Scientific Research Building No. 2 of Yongjiang Laboratory Agglomeration Area, the bottom part features a large and tall space, and the ratio of the storey height of the first floor to that of the standard floor reaches more than three times. In order to avoid a weak storey, three structural schemes, the reinforced concrete frame structure, the frame-shear wall structure, and the frame-steel bracing structure, were compared for the above-ground part, and the frame-steel bracing structural scheme was finally chosen. The planar and elevation layout of the steel braces was coordinated in accordance with the requirements of structural stress and architectural functions, and the joint analysis and design were carried out. In the overall design of the foundation, the structural design of the first floor slab was carried out according to the requirements of the user. The design of the floor slab and pile foundation was adopted, which can meet the requirements such as heavy load bearing, vibration isolation, and settlement reduction.更多还原
