Rectangular Frp Tubes Filled with Concrete for Beam and Column Applications
نویسنده
چکیده
This paper introduces an innovative concept of FRP/concrete hybrid structural member. This concept includes rectangular filament-wound glass fiber reinforced polymer (GFRP) tubes, totally or partially filled with concrete, and used as beams and/or columns. The paper presents the experimental program and results of three beams and five short columns tested with different eccentricities. Two of the beams were completely filled with concrete, while the third beam was partially filled to minimize the self-weight of the beam. This beam had a void within the cross-section, eccentric towards the tension side of the beam such that the remaining concrete was used to resist the internal compression and shear forces. Two of the columns were subject to zero eccentricity and the other three were subjected to various levels of eccentricity to study the combined effect of axial and flexural loading.

AN OPTIMIZATION PROCEDURE FOR CONCRETE BEAM-COLUMN JOINTS STRENGTHENED WITH FRP
This paper illustrates an optimization procedure of concrete beam-column joints subjected to shear that are strengthened with fiber reinforced polymer (FRP). For this aim, five different values have been considered for length, width and thickness of the FRP sheets which created 125 different models to strengthen of concrete beam-column joints. However, by using response surface methodology (RSM...

The behavior of concrete-filled fiber tubes (CFFT) polymers under axial compressive loading was investigated. Unlike the traditional fiber reinforced polymers (FRP) such as carbon, glass, aramid, etc., the FRP tubes in this study were designed using large rupture strains FRP which are made of recycled materials such as plastic bottles; hence, large rupture strain (LRS) FRP composites are enviro...

This study develops a new approach for forecasting shear Strength of concrete beam without stirrups based on the artificial neural networks (ANN). Proposed ANN considers geometric and mechanical properties of cross section and FRP bars, and shear span-depth ratio. The ANN model is constructed from a set of experimental database available in the past literature. Efficiency of the ANN model was c...
