摘要
比较了中国、美国、英国、日本、加拿大和澳大利亚等国家现行桥梁规范中的汽车荷载,着重讨论了荷载横向分布等桥梁简化计算方法,并以我国现行的JTG D60—2004公路桥涵设计通用规范为蓝本,对各国规范中的汽车荷载在不同桥跨、车道上所产生的各种响应做了计算分析,取得了一些有益的结论。
The vehicular live loads in current bridge design codes of China, USA, United Kingdom, Japan, Canada and Australia are compared in the paper. The concept of load distribution is emphasized, and all kinds of responses aroused by vehicular live loads based on current bridge codes of different countries are calculated, and compared, with different spans and traffic lanes, taking the active General Code for Design of Highway Bridges and Culverts （JTG D60-2004） as chief source. Some valuable conclusions are gained.
