INTRODUCTION AND COMPARISON OF CALCULATION METHODS OF THE STIFFNESS OF CONCRETE-FILLED CIRCULAR STEEL TUBES IN DIFFERENT CODES
-
摘要: 详细地介绍了美国AISCLRFD(99)规程、欧洲Eurocode4(EC4-94)规程、日本AIJ规程以及中国JCJ01-89规程、CECS28:90规程、DLT5085-1999规程中有关圆钢管混凝土构件刚度的计算方法。通过对比不同的计算公式,对上述各国规程中的刚度计算公式的建立思想与方法进行分析和说明。Abstract: The calculation methods of the stiffness of concrete filled circular steel tubes in different codes worldwide are introduced, which includes American Institute of Steel Construction(AISC)Load and Resistance Factor Design specification for structural building(LRFD), European Committee for Standardization(CEN) Eurocode 4Design of composite steel and concrete structuresPart 1 1:General rules and rules for buildings, Architectural Institute of Japan(AIJ)recommendations for design and construction of concrete filled steel tubular structures and the standards for structural calculation of steel reinforced concrete structures, Chinese design codes for the design of concrete\-filled circular steel tubes, which includes JCJ 01 89, CECS 28:90 and DL/T 5085 1999.The comparison is carried out for the different formulas of the stiffness in above codes and comments are made for the background of different stiffness formulas and their characters.
