【摘要】 基于脊骨梁中并排波形钢腹板挑梁支撑的预应力组合桥面板的结构特征和受力特点,进行了组合挑梁荷载横向分布试验和极限承载能力的全过程加载试验,同时与平面钢腹板组合挑梁的相应结果作了对比;通过对试验现象的描述和试验结果的分析,总结出脊骨梁中悬臂组合挑梁的主要受力、变形特点,以供工程实际参考。更多还原

【Abstract】 Based on the structural features and the mechanical properties of pre-stressed concrete bridge deck sustained abreast by steel cantilever beams with corrugated steel webs in spine girder,the loading transverse distribution experiment and the whole process loading experiment on ultimate bearing capacity of the structure were taken in this paper.They were compared with that of pre-stressed composite cantilever beams with plane steel webs at the same time.Via describing the experimental phenomenon and analyzing the results,authors summarized the main behaviors on mechanics and distortion of composite cantilever beams in spine girder for practical engineering.更多还原
