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 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...
According to EN 1993‑1‑5, 10 (5) a), it is necessary to determine all reduction factors with the modified slenderness ratio of the sheet metal ${\overline{\mathrm\lambda}}_{\mathrm p}$ according to Equation (10.2). Keywords Buckling analysis Plate buckling analysis Due to column ...
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 > 2.0J.Y....
rectangular, with a side ratio of 1:1-1:2. The buckling length may be reduced by connecting them together, esp. at the mid-point of the column length. The overall envelope of the cross-section of a group of struts is pref. approximately square. Low bending resistance in the desired ...
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...
