Due to ageing of bridges, a large number of bridges may not fulfill the requirements of the current scenario. Various
structural deficiencies occur in the bridges due to the increased traffic which consequently results in failure of the bridges.
Deficiency of bridge includes span and height issue, material quality and critical hogging and sagging moments , excessive
displacements and frequency of structure. A suitable change of material can prove to be the solution of all these dificiencies. A
typical model of a deck bridge structure is made on STAAD.PRO software and investigation of the same structure under two
cases namely RC bridge and Rubberised concrete bridge are performed as per IRC guidelines. The impact of change of geometry
is considered in terms of varying number of span , span length and pier height has been carried out under IRC conditions, then
the above models are compared in terms of various parameters like displacements in x , y ,z directions , bending moment , shear
force ,
