| 摘 要： | 简要介绍了美国ACI(1999)和AISC-LRFD(1999)、日本AIJ(1997)、英国BS5400(1979)、中国DBJl3-51-2003(2003)和DL／T5085-1999(1999)及欧洲EC4(1994)等设计规程中有关圆形截面钢管混凝土(以下简称圆钢管混凝土)压弯构件计算方法的特点，并将上述各方法及数值方法的计算结果和搜集到的圆钢管混凝土梁柱极限承载力实验结果进行了对比和分析。结果表明，在进行圆钢管混凝土梁柱极限承载力计算时，上述各规程提供的计算方法及数值方法均能较好地计算出构件的极限承载力，且计算结果偏于安全，其中，数值方法的计算结果与实验结果最为吻合，规程AISC-LRFD(1999)的计算结果最为安全。本文的研究结果可供进行圆钢管混凝土柱抗震设计时参考。

| Abstract: | Design methods of concrete-filled steel tubular beam-columns with circular hollow section in different codes, including ACI (1999, American), AISC-LRFD (1999, American), AIJ (1997, Japan), BS5400 (1979, British), DBJ13-51-2003 (2003, China),DL/T5085-1999 (1999, China), EC4 (1994, Europe) are introduced respectively in this paper. The calculating results of these codes methods and the numerical method are compared with those of tests.The analytical results demonstrate that all design codes can reasonably evaluate the ultimate bearing capacity of concrete-filled steel tubular beam-columns with circular hollow section, and tend to safety. The numerical results are better than the others, and AISC-LRFD (1999) is the safest one. The results in this paper may be referenced in seismic design of concrete-filled steel tubular columns with circular hollow section. |
