A multifunctional all-FRP joint has been developed for the transfer of bending moments and shear forces in thermal insulation sections of concrete slab structures used in building construction. Tensile forces from moments are transferred by horizontal GFRP ...
Temperature dependence of physical and mechanical properties is considered in most thermal and mechanical response models for composite materials. Based on thermogravimetry analysis, differential scanning calorimetry, and dynamic mechanical analysis conduc ...
A thermomechanical model is presented for predicting the time-dependent deflections of cellular FRP slab elements subjected to mechanical loading and fire from one side. The model comprises temperature-dependent mechanical property sub-models for the Young ...
The through-thickness performance of adhesive joints connecting pultruded FRP bridge decks and steel girders subjected to loading in the transverse bridge direction was investigated. Deck-to-girder adhesive joints can be assumed as being loaded by uplift f ...
The fatigue response of adhesively-bonded pultruded GFRP double-lap joints has been investigated under different environmental conditions. Tests were performed at -35 °C, 23 °C and 40 °C. A fourth set of fatigue data was collected from tests on preconditio ...
The multifunctional use of FRP composites offers the potential to contribute to the emergence of a new generation of lightweight engineering structures for an innovative infrastructure that meets the challenges with which today's construction industry is f ...

The through-thickness performance of adhesive joints between pultruded FRP bridge decks and steel girders was investigated experimentally and numerically. Through- thickness tensile stresses occur due to uplift forces caused by the load-bearing behavior of ...
As civil engineers seek to improve buildings and bridges, they are turning to composite materials for some structural components. Thus the long-term life of these materials in damp highly acidic conditions (from concrete pore solutions) is critical. This a ...
An active fire protection system, liquid-cooling, was applied to pultruded GFRP tubes subjected to combined thermal and mechanical loading in order to maintain material temperature below the critical glass transition temperature. The use of an appropriate ...
This paper presents a model to predict the shear resistance of the unreinforced lightweight concrete core of a recently developed hybrid sandwich concept for bridge decks. The sandwich skins consist of a fiber-reinforced polymer (FRP) composite sheet for t ...
