型钢混凝土结构(SRC)设计规程比较

COMPARISON OF THE SPECIFICATIONS FOR DESIGN OF SRC STRUCTURES

首先对日本及欧美等国外有关型钢混凝土(SRC)结构的设计规程进行了介绍,并简单介绍了我国现有的关于型钢混凝土(SRC)结构的两部规程《钢骨混凝土结构设计规程》(YB 9082-97)及《型钢混凝土组合结构技术规程》(JGJ 138-2001)的编制背景和依据。对两部规程中有关型钢混凝土梁的正截面抗弯、斜截面抗剪承载能力、型钢混凝土(SRC)偏心受压构件、剪力墙和梁柱节点的计算理论和计算方法进行了重点比较分析,并结合型钢混凝土(SRC)梁、型钢混凝土(SRC)偏心受压构件和梁柱节点承载能力的计算实例,对两部规程的应用方法、计算步骤和计算结果做了比较分析,为使用两部型钢混凝土结构设计规程提供参考。

The specifications for design of Steel Reinforced Concrete （SRC） structures of the foreign countries such as Japan, USA were introduced at first, and the two specifications for design of SRC structures in our country, which are the Technical Specification for Steel Reinforced Concrete Composite Structures （JGJ 138 -2001 ） and Specification for Steel- Reinforced Concrete Structures （YB 9082 - 97 ） were analyzed in detail based on their background. Discussions were focused on the calculation theory of the two specifications on bending and shearing load-bearing capacity of SRC beams, SRC eccentric compression columns, shear walls and beam-column joints. The design methods and calculation steps for the two specifications were presented by means of a series of calculation examples of typical SRC beams, and SRC eccentric compression columns and beam-column joints. Finally the detail requirements of SRC members in the two specifications were fully analyzed. This work is helpful to the engineering application of the two specifications in SRC structures design.
