钢管混凝土结构研究新进展——《空心钢管混凝土结构设计技术规程》简介

NEW DEVELOPMENT OF RESEARCH WORK FOR CONCRETE-FILLED STEEL TUBULAR STRUCTURES:BRIEF INTRODUCTION OF THE TECHNICAL SPECIFICATION FOR DESIGN OF HOLLOW CONCRETE-FILLED STEEL TUBULAR STRUCTURES

钢管混凝土结构具有性能优越和节省钢材等优点,已在高层建筑、工业厂房和一些构架中得到广泛的推广应用。除实心钢管混凝土构件外,出现了空心钢管混凝土构件。在截面形式上,除圆形和方形外,又出现了八边形和多边形。为了适应工程需要,作者主编了CECS《空心钢管混凝土结构设计技术规程》。规程的特点是要求适用于各种截面形式的构件设计,因而采用了《钢管混凝土结构统一理论》中的统一设计公式。这也为未来把各种钢管混凝土结构制定到一本规范奠定了基础。

Concrete-Filled Steel Tubular Structures（CFST）have a serious advantages. Hence, they had been used widely in high rise buildings, industrial buildings and a series of tower industrial structures. In recent yesrs, the hollow-CFST（H-CFST） members are adopted, exept the circular and square ones, the octagonal and multilateral cross-sections are appeared. The Technical Specification for Design of H-CFST Structures is edited to suit the needs of engineering development. The specification request is that,it must be to suit the various cross-sections of H- CFST members. Hence, the unified design formula of the unified theory for CFST Structures should be used. Which will be the base to establish a unified design standard of CFST structures in future.
