城市交通标志结构计算变形控制标准研究

Research on Calculation of Deformation Control Standard for Urban Traffic Sign Structure

城市交通标志结构设计时要求造型简洁、线条轻盈,而风荷载控制下的杆件水平变形往往成为决定杆件规格的主要因素。对于交通标志结构最大变形值的限定规范中并无明确描述,论文通过选取国内城市常用交通杆件进行变形验算,在保证交通标志结构正常使用的基础上,分析得出交通标志结构变形控制建议值。

In the design of urban traffic sign structure, it is required that the shape is simple and the line is light, and the horizontal deformation of members under the control of wind load is often the main factor to determine the specifications of members. There is no clear description in the limit specification of the maximum deformation value of the traffic sign structure. The paper selects the common traffic members in domestic cities for deformation checking calculation, and on the basis of ensuring the normal use of the traffic sign structure, analyzes and obtains the proposed value of the deformation control of the traffic sign structure.
