PRIMARY RESEARCH ON CALCULATIONS FOR BEARING CAPACITY OF CONCRETE FILLED HIGH STRENGTH STEEL TUBULAR MEMBERS

对高强钢管混凝土构件研究成果进行总结,并利用数值计算方法对高强钢管混凝土压弯构件荷载-变形关系曲线进行计算,计算结果与试验结果吻合较好。最后对设计规程DL/T5085-1999、GJB4142-2000(2001)、AIJ(1997)、EC4(1994)、AISC-LRFD(1999)和DBJ13-51-2003(2003)在进行高强钢管混凝土构件承载力计算时的适用性进行比较。

The research results of concrete filled high strength steel tubular members are summarized, then numerical method is applied in the analyses of load-deformation relations curves of concrete filled high strength steel tubes beamcolumns, and calculated results agree well with tested results. Finally, a comparison is made to understand applicability of different codes including DIJT 5085-1999, GJB 4142 - 2000（2001 ）, AIJ（1997）, EC4（ 1994）, AISC - LRFD（ 1999）, and DBJ 13 - 51 - 2003（2003） for calculating beating capacity of concrete filled high strength steel tubes beam-columns.
