前言混凝土高桥墩纵向弯曲问题,实际上就是研究混凝土高桥墩轴心受力和偏心受力的压杆问题。例如公路和铁路桥梁的桥墩,水工建筑中承托渡槽的支墩等均属此类问题。目前,这个问题的计算方法尚值得深入研究探讨。本文旨在(1),根据混凝土弹性模量实验资料,制作了与现行模范不同的纵向弯曲系数φ值表;(2)对混凝土高桥墩变截面及自重的影响提 Preface The longitudinal bending of high concrete piers is actually a research on the pressure bar problem of axial compression and eccentric stress of concrete high piers. For example, piers for highway and railway bridges, piers for supporting aqueducts in hydraulic structures are all examples of such problems. At present, the calculation of this issue is still worth further study. The purpose of this paper is as follows: (1) According to the experimental data of concrete elastic modulus, the vertical bending coefficient φ table which is different from the current model is produced; (2)
