|Title:||Benefits of timber-concrete composite action in rural bridges|
|Abstract:||Timber-concrete structures can be applied to bridge superstructures of vicinal roads with innumerable advantages in relation to the usual structures made of timber or reinforced concrete. This paper presents both an experimental analysis and a theoretical study on models of bridges with timber and concrete composite structures whose systems of connections composed by nails or screws are semi-rigid. The experimental procedure consisted basically of bending tests in three panels, representing a bridge prototype to evaluate the performance structural. Besides this in order to define the slip modulus shear tests in small specimens were performed. The theoretical study was based on differential equations developed from the equilibrium of forces and the compatibility of displacements and these results were compared to the Finite Element Method. From this analysis, it can be concluded that the timber-concrete composite structures have favorable perspective of application in this type of civil construction.|
