Parametric studies reveal that under the same steel ratio, gross cross sectional area and length, square columns lead to better capacities than rectangular columns for Mx/My < 2.0. The advantage of using a rectangular long column could only be achieved when Mx/My > 2.0doi:10.1080/02533839.1993.9677508YenJ.Y. RichardTaylor & ...
The slenderness ratio of an FRP-confined RC column is herein defined as λ = le/r, where le is the effective length of the column and r is the radius of gyration. Based on the numerical results produced by the analytical model presented in Jiang and Teng (2006), the following expression...
The torsional behavior and performance of the CFST members under local compression were also studied in recent years [7], [8]. Due to many advantages such as high strength/weight ratio, good corrosion resistance, easy construction and low cost etc, Fiber Reinforced Plastic (FRP) has been ...
Based on the seismic provision [15], from the strength point of view, a connection is acceptable if the ratio of Mcf and Mpb at 4% total rotation is greater than 0.8. Hence, it might be concluded that, for a WFP connection which is even designed based on the seismic provisions, its ...
Slenderness ratioAxial behaviorIn the construction industry, carbon fiber-reinforced polymer (CFRP) composites are widely used for retrofitting and rehabilitation of reinforced concrete (RC) rectangular columns to enrich the service life of structures. The CFRP-confined RC rectangular column with a ...
The performance of existing confined strength models is evaluated and modified to accommodate different types of high-performance concretes and column shapes. The modified model improves the prediction of confined concrete strength with a mean predicted-to-experimental ratio of 1.05 as shape and concrete...
width-to-thickness ratios, leaving a gap in understanding the full spectrum of CFT column behavior. In this sense, these investigations have demonstrated that the cyclic behavior of CFT columns is strongly influenced by factors such as width-to-thickness ratio, axial load, and material ...
