摘要
通过对72个圆心角为90°的双跨偏心支承弯箱梁桥模型的计算分析,以梁格系法为基础编制的3D- BSA软件系统为结构计算工具,以Excel2 0 0 0为数据处理工具,用统计分析的方法建立双跨偏心支承弯箱梁桥结构反应在使用极限状态及承载能力极限状态下与桥梁跨长、支承偏心距等参数间的经验公式,为双跨偏心弯箱梁桥的实用设计提出适当建议或借鉴依据。
In this paper 72 models of a two-span curved box-girder bridge with 90-degree central angle and eccentric support are made,software system 3D-BSA is used to compute, Excel 2000 to treat dada,and statistic analysis method to set up empirical formulas between structure responses and parameters, such as bridge span and eccentricity of support for this type of bridges under service capacity state and carrying capacity state, so as to make some suggests or basis for pracical designs.
