由原能源部电力规划设计管理局批准实行的《火力发电厂主厂房钢-混凝土组合结构设计暂行规定》(DLGJ 99-91),第三章订有“钢管混凝土结构”的内容,为便于设计和应用者了解掌握,本文特将该章内容的编制背景,设计方法和特点,分前言和六个部分(含构件轴压、拉、剪、弯、压弯的强度与稳定,刚度和变形计算,框架梁柱节点加强环板的设计)作了简要介绍。
The “Provisional Regulations for the Design of Steel-Concrete Composite Structures in Main Power Plants of Thermal Power Plants” (DLGJ 99-91) approved by the Department of Electric Power Planning and Design Administration of the Ministry of Energy, and the content of the “Concrete Pipe Structures for Concrete-Filled Steel Tubes” in Chapter 3 has been designed for ease of design. And the applicators understand and master, this article specializes in the background, design methods and characteristics of this chapter, divided into the preface and six parts (including the calculation of strength, stability, stiffness and deformation of axial compression, tension, shear, bending and bending of components). A brief introduction was given to the design of the stiffening ring plate for frame beam-column joints.
