摘要
比较分析了中美印三国桥梁设计规范中关于汽车荷载的规定,包括名义车道划分、车道荷载、车辆荷载、冲击系数、折减系数、布载方式等方面,并通过工程实例说明三国规范中汽车荷载的差异。比较发现,汽车荷载作用下,根据美国规范算出的跨中弯矩及位移值最小,印尼规范最大,中国规范居中。
This paper compares and analyzes the stipulations of motor vehicle loading including the lane partition, lane loading, vehicle loading, impact coefficient, reduction coefficient and load arrangement in the bridge design norms of China, USA and India, and explains the differences of motor vehicle loadings in the norms of China, USA and India. The comparison shows that the norm of India is the maximum, the norm of China is centered, and the mid-span moment and displacement value of USA are the minimum under the motor vehicle loading according to the norm of USA.
