中小跨径曲线钢箱梁桥因其自重轻、热容低、热膨胀系数大等优点，在城市基础设施建设中得到了广泛的应用。但是，太阳曝晒容易使钢箱梁底部最大温差增加25 ° C。在非均匀温度场和超载车辆的作用下，曲线钢箱梁桥内侧边缘可能与其余结构分离，导致倾覆。因此，需要更加注意以防止分离。对杭州市某三跨曲线钢箱梁桥进行了抗倾覆分析。在实测钢箱梁温度场的基础上，提出了钢箱梁温度场的计算模型.预测了温度变化引起的分离位移，并通过测量结果进行了验证。因此，支持R...
AbstractOwing to its light self-weight, low heat capacity and large thermal expansion coefficient, the application of the curved steel box girder bridge with small and medium spans has gained popularity for the construction of urban infrastructure. However, sun exposure could easily increase the maximum temperature difference at the bottom of steel box beam by 25°C. With the effect of nonuniform temperature field and overloaded vehicles, the edge inside the curved steel box girder bridge may be separated from the remaining structure, resulting in overturning. Thus, more attention needs to be paid in order to prevent the separation. In this paper, an overturning resistance analysis of a three-span curved steel box girder bridge located in Hangzhou, China was performed. A model was proposed based on the measurement of temperature field to the steel box girder. The separating displacement due to temperature variations was predicted and verified by the measurement results. As a result, changes in supporting r...
