【摘要】 <正> 一、概述 箱形梁具有很大的抗扭刚度,对桥梁承受偏心荷载和在大跨度桥梁悬臂施工时的横向稳定等都很有利。所以很适合于大跨度公路桥梁和城市桥梁,在进行箱形梁设计时,在箱形梁中设置横隔板已经成为惯例。但是,在选用横隔板的数量及布置其位置时却常常缺乏确切的根据,在箱梁中布置横隔板将增加箱梁的静重,例如,一个跨度为150英更多还原

【Abstract】 In this paper, the functions of diaphragms are analyzed first, and the necessity to install diaphragms near the supports is then pointed out. Based on the obtained experimental results, a method for deciding the interval of diaphragms is proposed and the experimental results of multicells box girder are given.更多还原
