Abstract:
The civil engineering fields of FRP (Fiber Reinforced Polymers) pultruded profiles are the structural rehabilitation of the existing constructions and the new buildings. In the first case the FRP intervention is ancillary to masonry construction as beams and trusses for roofs and floors; while, in the second case, the all-FRP structures are for over elevation frame, emergency and specific structures in complex conditions. The non-linear responses of masonry structures with truss beams made of pultruded FRP profiles and traditional materials have been compared through finite element models subj

This paper presents the mechanical behaviors of hybrid fiber reinforced plastic (HFRP) composite beams. There are two methods were proposed to increase the stiffness of pultruded glass fiber reinforced plastic (GFRP) beam and change the failure mode. The first method is to infill the epoxy mortar into the GFRP beam. The second method is hand layout the GFRP beam by using carbon fiber with different direction fibers to increase the stiffness of the GFRP beam. Three-point bending test was conducted to obtain the force-displacement relationship, stiffness, failure strength and failure mode of the

Acoustic emission (AE) released by pine beams retrofitted with fiber reinforced plastic (FRP) and poplar planks in bending is analyzed. Basalt fabric (FB), carbon fabric (FC), and carbon pultruded laminate (LC) have been used as FRP. Experimental results and AE behavior are discussed based on an elastoplastic finite-element numerical model. The model demonstrates a strong strain concentration at the end of poplar planks, which causes high AE activity in these areas and acts as a precursor of the delamination of the poplar plank. Based on the experimental results, some AE criteria for predictin

Abstract:
Pultruded fiber reinforced polymer (FRP) structural members have been used in various civil engineering applications. T-shapes are commonly used for chord members in trusses and for bracing members. In these cases, T-shapes are mainly subjected to axial forces, and stability of a member is one of the major concerns in the design. Due to the monosymmetry existing in the cross-section of T-shapes, T-shapes are likely to buckle in a flexural-torsional mode. An energy solution, using the Ritz method, to the buckling problem of a pulturuded T-shape under uniform compression is derived based on a co
