The basis of little and morrice method, K.S. rakshit method is that the stiffness of cross girder are taken into account ( by parameter alpha and theta) but not infinitely rigid.
Greetings,
Currently, i am checking the viability of 4 lane of RCC T beam bridge. The features of bridge are:
Span= 25m
No. of longitudinal girder =6
Depth of longitudinal girder = 2.5m
I have modeled in sap and done manual calculation.
The live load distribution among the longitudinal girder...
