公路桥梁车辆及车道荷载与折减系数的研究

Vehicle and Lane Loading with Its Reduction Factor Study in Highway Bridge Design

在公路桥梁设计中 ,经常遇到多车道的布置而且桥梁的跨径日趋增大。必须考虑多车道横向折减及纵向折减。对折减系数做精辟的研究与综述。

In bridge design,wider deck and larger span are encountered in practice.In this case,it is necessary to consider the multiple_lane reduction factor as well as longitudinal discount on the structural response.In this paper,these two reduction factors are studied theoretically and summarized with new recent findings.
