【摘要】 斜支承箱梁桥具有特殊的结构反应。本文利用某预应力混凝土斜支承连续箱梁桥的有机玻璃模型的试验结果,对这种特殊结构的支反力、挠度、内力及其横向分配特性等进行了理论分析与试验研究,并与相应的正交支承箱梁桥进行了比较。详细分析斜支承的角度变化和外荷载的不同位置对箱梁性能的影响,清晰地展示了斜支承箱梁桥的结构反应规律。更多还原

【Abstract】 Structural response of skewly supported box-girder bridges has particularcharacteristics. In this paper, based on the test results of a plexiglass skewlysupported box-girder bridge model, theorectical analysis and experimentalresearch are made for the support reaction, deflection, internal force andcharacteristics of the transverse distribution of the above properties. Thebehaviour of the skewly supported box-girder bridge is compared with that ofthe normally supported box-girder bridge. The influence of the skew angle andloading location on the behaviour is analysed in detail, showing clearly thestructural response characteristics of this kind of bridges.更多还原
