江老师,您好,还想请教您几个问题:
1,在利用midas 通过梁格法建立连续箱梁模型时,支左位置该如何模拟?
2,车辆静载是加在横梁上,还是应该利用扭矩加在半主梁单元上,如果加在主梁上,两个半主梁单元如何分配荷载呢?
3,横向联系梁的截面特性如何模拟才能比较准确?
谢谢江老师,给你添麻烦了

1,在支座处将单元分节点,然后加支座。
2,不是非常明白您的情况。按我的理解,对于横梁比较密的情况,可以加在横梁上。
3,可以考虑一些梁格方面的书,如人民交通出版社的《桥梁上部构造性能》,汉勃利编,1982年出版。

谢谢江老师,还有一个问题请教您.
梁格模型中施加活载时,不知为什么,我不能利用横向联系梁组,是否可以在横梁上建立虚拟梁,(如拱桥建模例子中的虚拟梁),还是利用通过主梁单元的
车道偏心值,进行计算?

不知道为什么不能横向联系梁组?
用虚拟梁是可以的。不过,会增加计算的时间的。
用主梁偏心的方法不太好,误差较大。
