摘要
本文对国内外常用的计算冲击力的方法进行了讨论.针对其不足之处,提出一种将汽车和护栏作为连续系统的动力计算方法,并与作者所做的载重汽车直接冲撞钢筋混凝土护栏足尺模型试验结果进行了比较,计算结果良好.
This paper deals with the defect of methods currently used at home and abroad for calculating vehicle impact forceacling on reinforced concrete guardrail. A dynamic method is proposed in this paper to calculate the impulsive force in which the motor vehicle and barrier are considered as a continuous system.The theoretical predications have a good agreement with the test results of the full scale reinforced concrete barrier model- impacted by truck.
