摘要
荷载横向分布系数是装配式桥梁设计、检测、验算的重要依据,以省内县乡道路上修建于20世纪70年代结构简支桥面连续T梁桥为背景,通过简化方法计算和实体模拟,计算出其理论解和数值解,与经过多级加载的实测横向分布系数对比,得出接近工程实际情况的计算方式,结果可为该类T型梁桥检测评定提供参考和借鉴。
Taking a simply-supported bridge deck continuous T-beam bridge as the background, through the simplified method calculation and the physical simulation, this paper calculated the theoretical solution and numerical solution. Compared with the measured transverse distribution coefficient with multi-stage loading, it also drew the calculation method that close to the actual situation of the engineering. The results could provide reference for the detection and evaluation of the T-type beam bridge.
