In this paper, we analysis the prestressed concrete curved continuous girde bridge by the energy method, give the internal forces and deflections of loads and prestressing, and the de-sign method of prestressing. 本文用能量法对预应力砼曲线连续梁进行了全面分析研究,给出梁在任意荷载作用下的内力、变形,预应力产生的内力及合理的配筋方法。
Therefore, the construction procedures of the transverse diaphragms and ribs steel box and concrete box hybrid girder cable-stayed bridge and the detailed stress of steel box girde are comprehensively understood, and analysing method of complex bridge is mastered. 由此,作者较清晰地认识了横隔板横肋式钢箱梁与混凝土梁混合斜拉桥的施工过程受力和钢箱梁的详细受力,掌握了运用有限元软件对复杂桥梁结构的计算分析方法。
