现行设计汽车荷载纵向折减系数的适应性分析

以可靠性理论研究为基础，结合实测的车辆荷载数据，从实测荷载效应与标准车辆荷载效应比值的概率分析中得到标准车辆荷载纵向折减的计算公式及桥梁纵向折减系数的建议值。多座大跨径实桥的实际计算结果证明，采用该研究建议后的折减效果是合理的。

Adaptiveness of Longitudinal Vehicle Load Reduction Coefficient in Current Design

Based on the reliability theory, by using the measured vehicle load data, this paper gets the longitudinal load reduction formula of the standard vehicle load and the recommended value from the probabilistic analysis of the ratio between the measured load effects and the standard one. The actual calculation results of many long-span bridges prove that the reduction effects by adapting the research proposal is reasonable.
