Punching behaviour of column-slab connection strengthened with non-prestressed or prestressed FRP plates

Analytical Solutions for the Flexural Behavior of Metal Beams Strengthened with Prestressed Unbonded CFRP Plates

Trapezoidal prestressed unbonded retrofit (TPUR) systems have been recently developed and tested. The authors have already developed a comprehensive and accurate analytical solution for the TPUR system that takes many system parameters into account. The main aim of this paper is to develop a simplified analytical solution for predicting the behavior of metal beams that have been strengthened wi...

Strengthening of Impacted Prestressed Concrete Bridge I-Girder Using Prestressed Near Surface Mounted C-FRP Bars

Ductility of Prestressed and Partially Prestressed Concrete Beam Sections

D analyses of structures responding elastically to ground motions recorded during severe earthquakes have shown that the theoretical response inertia loads are generally significantly greater than the static design lateral loads recommended by codes. Hence, structures designed for the lateral earthquake loads recommended by codes can only survive severe earthquakes if they have sufficient ducti...

Flexural Behaviour of Precast, Prestressed Ribbed RPC Bottom Panels

This study introduces a new type of precast, prestressed reactive powder concrete (RPC) bottom panel for a large-span composite slab. The bottom panels, which have one or two inverted ribs with openings, act as formwork during the construction stage. The paper experimentally investigated the crack characteristics, deflection, and normal section bearing capacity of four precast, prestressed ribb...

Finite Element Modelling of Steel-concrete Composite Beams Strengthened with Prestressed Cfrp Plate

This paper presents results from Finite Element Modelling (FEM) of steel-concrete composite beams strengthened with prestressed Carbon Fibre Reinforced Polymer (CFRP) plate. For the purpose of this study, three beams were strengthened using prestressed CFRP plate with three different levels of induced prestressing force. The models were developed using ANSYS FE package. The results of an experi...
