某商业综合体大跨度弧形连桥设计分析

Design Analysis of a Large Span Curved Continuous Bridge in a Commercial Complex

连桥跨度41m,宽度6.5m,截面高度1200mm,高跨比约1/34。通过合理设计,其强度与挠度均能满足要求,舒适度验算能达到CL1舒适度等级,舒适度评价可为“最佳”范畴。为高跨比达1/34的连桥设计与分析,提供了案例。

The connectingbridge spans 41 m,has a width of 6.5 m,a section height of 1 200 mm and a high-span ratio of about 1/34.Through reasonable design,its strength and deflection can meet the requirements,the comfort check can reach the CL1 comfortable level,and the comfort evaluation can be considered into the"best"category.A case study is provided for the design and analysis of a bridge with high span ratio of 1/34.
