摘要
城市道路功能的不断发展刺激了智慧合杆的形成。智慧合杆的设计重要且复杂,急需一种便捷合理的计算模式。采用3D3S钢结构-空间结构设计软件对12 m双臂柳叶智慧合杆模拟建模并进行受力分析,计算过程可充分考虑结构恒载、活载、最不利方向风载以及附加地震荷载等实际使用环境。验算结果表明杆件最大应力比为0.527,最不利受力方向弯矩为绕X轴弯矩52 k N.m,参数满足要求,且与手算结果45.2 k N.m相差较小,计算结果可靠。后续可根据需要进一步优化确定杆件最合适的口径与壁厚,并计算出杆件所需柱脚大小与基础坑尺寸。3D3S软件结构建模简单,受力分析速度快,符合国家相关标准要求,且设计更具有经济性与安全性,能很好的适用于智慧合杆的工程设计。但3D3S软件在针对复杂灯头等部件的设计时仍有欠缺,需寻找更合理的建模及细节处理方式。
The continuous development of the urban road functions stimulates the formation of smart integration pole.The design of smart integration pole is important and complex,so a convenient and reasonable calculation model is urgently needed.In this article,software 3D3S is used to simulate and analyze the stress of 12-meter double-arm LIUYE smart integration pole,which takes full account of the actual usage of the structure,such as dead load,live load,wind load in the most unfavorable direction and additional seismic load,etc.The result shows that the parameters meet the requirements and the maximum stress ratio is 0.527,the bending moment in the most unfavorable direction is 52 kN.m of X-moment;the difference between the result and the manual calculation result 45.2 kN.m is small,and the calculated result is reliable.The most suitable diameter and thickness of the pole can be optimized as required,and the size of the column foot and base pit also can be calculated.3D3S can be applied to the engineering design of the smart integration pole well for it has the characteristics such as simple model building,fast force analysis,accorded with the relative national standards,and more economical and safe.However,3D3S is still lacking in the design of complex lamp caps and other components,it is necessary to find a more reasonable modeling and detail processing methods.
