摘要
为解决城市道路交通标志牌基础与市政管线之间的冲突,合理确定标志牌基础尺寸。首先采用有限元软件对标志牌振动模态进行分析求得其自振周期,确定是否考虑顺风向风振的影响;再依据新版《建筑结构荷载规范》(GB 50009-2012)进行风荷载计算,并在一定的约束条件下对基础的尺寸进行分析,合理确定基础尺寸的大小;最后,结合实际工程对标志牌基础与市政管线之间的冲突问题提出了解决方案。
In order to solve the conflict between the urban road traffic sign foundation and the municipal pipelines,it is to reasonably make sure the foundation dimensions of signs.The finite element software is used to analyze the vibration mode of signs so as to obtain its natural vibration period and determine whether or not to consider the effect of wind vibration along wind.Based on the new edition of Load Code of Building Structure(GB50009-2012),the wind load is calculated.The foundation dimensions are analyzed and reasonably determined under certain constraints.Combined with the practical cases,the solving scheme is proposed for the conflict between the sign foundation and municipal pipeline.
