NONLINEAR ANALYSIS OF HOLLOW-CORE SLABS WITH

2019-1-22  Abstract: In this study, a numerical model about the shear behaviour of precast prestressed hollow-core slabs is presented. The nonlinear analysis is conducted using the Abaqus software and the results are expressed as a comparison between hollow-core units with and without fiber reinforced polymers. Fiber Reinforced Polymer (FRP) composite is commonly used to strengthen and retrofit a large number of structural elements, being a high strength composite material made of a polymer matrix reinforced with fibers. The shear strengthening technique consists in the appliance of FRP on the inner surface of the slab’s

2006-2-25  A tendon model that can effectively be used in finite element analyses of prestressed concrete (PSC) structures with bonded tendons is proposed on the basis of the bond characteristics between a tendon and its surrounding concrete. Since tensile forces between adjacent cracks are transmitted from a tendon to concrete by bond forces, the constitutive law of a bonded tendon
