| 摘 要： | 通过对组合连续梁负弯矩区影响因素的建模分析,建议超高性能混凝土(UHPC)桥面板厚度与组合梁高度之比为1/5～1/9,组合梁高度与跨径的比值为1/18～1/22,钢梁与UHPC桥面板刚度之比为2～10;钢-UHPC组合连续结构梁高远低于钢-C50混凝土组合连续梁结构梁高,结构负弯矩区UHPC桥面板不开裂.

| Abstract: | By modeling and impact analysis of negative moment zone of composite continuous beam, it is suggested that the ratio of thickness of UHPC deck to the height of composite beam is 1/5~1/9, the ratio of height of composite beam to the span is 1/18~1/22, and the ratio of rigidity of steel beam to UHPC deck is 2~10. The height of steel-UHPC composite continuous beam structure is much lower than that of steel-concrete composite continuous beam structure, and the UHPC deck in the negative moment zone of the structure does not crack. |
