中俄规范在铁路钢桁梁桥设计中的应用研究

在某国际铁路钢桁梁桥设计过程中,对中、俄两国现行桥梁设计规范计算结果进行对比,同时,采用中国试行极限状态法规范进行试算,比较3种规范的差异性和计算结果的安全储备。中国两种规范设计结果安全储备相差不大,而与俄方规范相比,不同检算项目相差较大,俄方规范对压杆强度控制更为严格,中国规范对疲劳强度控制更为严格。

Application of Chinese and Russian Specifications in the Design of Railway Steel Truss Bridge

In an international railway steel truss bridge design,both Chinese and Russian design code were employed,and the Chinese Interim code for limit state design was also used. The comparison of the differences and calculation results of the three codes show that two Chinese design results are similar in safety reservation. While the comparison with Russian specification shows that the results are much different for different item. For the strength of compression bar,Russian code is tighter,while,for the fatigue strength of tension bar,Chinese code is stricter.
