English Abstract
This research presents a theoretical study depends on Adecola approach of behaviour of continuous composite beams with external prestress , a reinforced concrete slab and steel shapes connected together by stud shear connection.
In this analysis, the region of the negative moment is considered thoroughly since the concrete component of the composite section will be subjected to tensile stresses and will affect its contribution to the composite couple.
Moreover, the continuous end will satisfy several boundary conditions different from the simply supported end.
A linear analysis of continuous composite beams with external prestress including the influence of slip and separation.
The optimization principles have been employed to the contribution of the prestressed force between the steel and concrete.
The constrained Rosenbrock method has been used in order to specify the maximum contribution of the prestressed force and moments.
The governing linear differential equations are derived in terms of (U(d2T/d2x), T(uplift pressure) and F(axial force)), and solved using an iterative finite difference scheme representation.
The influence of prestressing is shown to reduce the slip and center deflection and increase in the ultimate capacity of the section.
The study gives an indication of how the ductile behaviour of a prestressed continuous composite beam compared with the continuous composite beam only, the main studied variables are slip, deflection and axial force The prestressed composite structure requires additional computation over the composite structure, which always give us additional advantages in new structures.
The general behaviour is the same except that the prestressed beam exhibits higher yield and ultimate resistance to the applied moment efficient.
