某会展中心大跨交叉钢-混凝土组合梁系楼盖设计

Design of a long-span two-way steel-concrete composite beam floor system for a conference exhibition center

本文结合某会展中心的大跨楼盖结构设计,介绍了大跨交叉钢-混凝土组合梁系楼盖的主要设计思路及构造方法,并介绍了复杂节点的构造措施。通过跨高比、用钢量等技术指标说明应用大跨交叉钢-混凝土组合梁系楼盖具有显著的技术经济效益。工程实践表明,这种大跨楼盖结构应用前景广阔。

The present paper briefly introduces the design concept and constructional details of long span two way steel concrete composite beam floor system through the case design of a conference exhibition center. The depth to span ratio of the beam and the steel weight per unit floor area have indicated that the long span two way steel concrete composite beam floor system is quite rational and economical. This actual application has shown a promising future of this system.
