“…Zhan and Wu [30,31] developed an innovative closed-form design equation based on the Ayrton-Perry formula to estimate the load capacity for pultruded doubly symmetric cross-sections subjected to global buckling. Kulkarni [32] studied the buckling of I-section pultruded profiles under uniform axial compression.…”

This article reports the finite element (FE) investigation of the axial capacities of pultruded fiber-reinforced polymer (PFRP) composite channel columns. The nonlinear finite element model (FEM) was developed by using the ABAQUS package for glass fiber-reinforced polymer (GFRP) composite channel columns, which included geometric and initial geometric imperfections. The developed FEMs were verified against an experimental result available in the literature for GFRP channel columns. The validated FEMs were used to carry out the parametric study comprising 61 FE models to investigate the effect of different geometries, plate slenderness and the length of members on the axial capacities of GFRP pultruded channel columns. The results obtained from the parametric study were used to examine the accuracy of the current Italian guidelines, American pre-standard and the Direct Strength Method (DSM) proposed in the literature for GFRP channel profiles. Based on the obtained results, the suitability of the current design guidelines is assessed and, also, a new set of design equations is proposed to estimate the axial capacity of the pultruded GFRP channel columns. The new proposed set of reliable design equations witnessed a less scattered and a high degree of accuracy in determining the axial load capacity of the pultruded GFRP composite channel columns.

“…In addition to the corrosion related issues, the loss of prestress force which can go upto 24% is another major concern for steel PC members [4]. Due to the above reasons there has been considerable research in the past to replace the steel strands in PC members with FRP bars [5][6][7][8]. The most widely accepted materials used in the fibers of FRPs are aramid and carbon.…”
