中美钢结构规范关于高强螺栓性能及连接构造要求的对比

Comparison of Performance and Connection Structure Requirements of High-strength Bolts in Chinese and American Steel Structure Codes

近年来,钢结构由于其轻质高强、抗震性能好、建造工期短、适合大跨度建筑等优点得到了更加广泛的应用,而高强螺栓连接是钢结构设计中节点连接的常用形式。随着我国经济的快速发展,涉外工程项目逐渐增多,了解国外规范对于高强螺栓的相关要求显得十分必要。为此,根据目前最新版本的美国钢结构设计规范AISC360-16与中国钢结构设计标准GB 50017—2017,介绍了中美设计规范中关于高强螺栓性能参数及连接的构造要求并进行了对比分析,可供设计人员参考。

With the advantages of light self-weight,high strength,anti-seismic performance,short construction period and fitness for long-span architecture,steel structure has been widely applied in recent years,and high-strength bolt connection is commonly used in steel joint design.It is necessary to understand the requirements of foreign standards for highstrength bolts because the rapid growth of China’s economy and the gradually increasing foreign projects.According to the American standard Specification for Structural Steel Buildings(AISC 360—16)and Chinese standard Standard for Design of Steel Structures(GB 50017—2017),the performance parameters and structural connection requirements of high-strength bolts are introduced and compared,which can be used as reference for relevant designers.
