钢箱—混凝土组合梁正截面承载力的初步研究
|
摘要
基于方钢管混凝构件和箱形梁的特性 ,提出了钢箱—混凝土组合截面梁 ,并给出了正截面极限承载力计算方法 ,根据使用条件 ,提出了可能的截面形式。完成了一根梁的初步试验研究 ,并与某特大桥的主梁进行了综合比较 ,综合分析表明钢箱—混凝土组合截面梁具有良好的应用前景。
The steel box concrete composite beam is proposed in the paper;it is a new type of structure It is based on the behavior of concrete filled steel tubular members with square section and box girder A formula for ultimate bearing capacity of normal section is derived At same time,a piece of composite beam is tested in the laboratory A load deflection curve is obtained;it is basically agreed with that of the theoretical one A synthetical comparison is made with the main girder of an extra long span bridge The study shows that the steel box concrete composite beam has a good prospect
