摘要
简要介绍了美国LR FD(1994)、日本A IJ(1997)、欧洲EC4(1996)设计规程中有关矩形钢管混凝土压弯构件的设计方法;同时介绍了我国即将颁布的《矩形钢管混凝土结构技术规程》中压弯构件的设计方法及简化的M—N相关曲线,并利用该方法的计算结果和文献[1]中30个矩形钢管混凝土的试验数据,进行了对比分析.结果表明:《矩形钢管混凝土结构技术规程》用极限状态计算矩形钢管混凝土偏压柱的M—N相关曲线是合理的,且用简化相关方程计算单向偏压柱的承载力是偏于安全的.
Design methods of concrete-filled rectangular steel tube compression-bending members in different codes, including LRFD（1996, American）, AIJ（1997, Japan）, EC4（1996, Europe） were introduced concisely in this paper. And design method of “technical specification of concrete-filled rectangular steel tube members” in china was introduced also. The calculating results were compared with test results of the paper. The analytical results demonstrate that the design method of concrete-filled rectangular steel tube compression-bending members is reasonable and tend to be with safety.
