Analytical prediction methods for axial stresses and deflections at the serviceability limit state and for ultimate failure loads are proposed for hybrid bridge girders consisting of FRP bridge decks adhesively bonded to steel girders. The methods allow fo ...
This paper reports on the composite action developed between pultruded FRP bridge deck systems and the supporting main girders for road bridges. Presented are requirements that an FRP deck must satisfy in order to function as part of the upper chord of the ...
This paper presents an experimental study on the fire behavior of glass fiber-reinforced polymer (GFRP) load- carrying slabs for building and bridge applications. Fire experiments were performed on cellular full-scale slabs with and without internal liquid ...
The in-plane tensile performance of a pultruded FRP bridge deck system was examined with regard to the use of the deck as the compositely acting top chord of hybrid bridge main girders in negative moment regions. The deck properties determined on the syste ...
A new model is proposed to estimate the post-fire stiffness of FRP composites after different fire-exposure times. The model considers the E-modulus recovery of the material if cooled down from temperatures between glass transition and decomposition during ...
This paper presents a new concept for a lightweight hybrid- FRP bridge deck. The sandwich construction consists of three layers: a fiber-reinforced polymer composite (FRP) sheet with T-upstands for the tensile skin, lightweight concrete (LC) for the core a ...
A decomposition model for resin in glass fiber-reinforced polymer composites (GFRP) under elevated and high temperature was derived from chemical kinetics. Kinetic parameters were determined by four different methods using thermal gravimetric data at diffe ...
In the summer of 2005, after eight years of use as a temporary bridge during the winter, the Pontresina Bridge for pedestrians was transported to the Swiss Federal Institute of Technology Lausanne for a detailed assessment of the structural safety, service ...
An existing hybrid-GFRP/steel joint for load transfer and thermal insulation in concrete slab structures was developed into an all-GFRP joint. The new joint consists of a pultruded GFRP tensile/shear element anchored through adhesively bonded ribs in the c ...
A durability study was performed on a pultruded glass fiber reinforced polymer (GFRP) compression element of a hybrid GFRP/steel joint for concrete structures. GFRP elements were immersed in alkaline pore water solutions of different temperatures during 18 ...
