A finite element approach for the non-linear behaviour of externally prestressed continuous composite beams with flexible shear connection is proposed. The displacement control method adopted to solve the non-linear problem makes it possible to capture the complex non-linear behaviour of the girder even if fragile failure occurs.

Abstract
A finite element approach for the non-linear behaviour of externally prestressed continuous composite beams with flexible shear connection is proposed. The displacement control method adopted to solve the non-linear problem makes it possible to capture the complex non-linear behaviour of the girder even if fragile failure occurs. Some applications on a two-span continuous beam are discussed showing the importance of the limited ductility of the shear connection in defining the collapse mechanism.File in questo prodotto:
