摘要：

A three-dimensional finite element models are developed to simulate the response of circular reinforced concrete columns confined with various configurations of CFRP composites. SOLID65, SOLID45, LINK8, and SOLID46 elements represent concrete, steel plates, discrete reinforcing steel bars, and CFRP sheets, respectively. Based on actual characteristics for each component, nonlinear material properties are defined for each type of elements. The FEA results are made in terms of axial load-axial displacement response, axial load-axial strain and circumferential responses, and stress-stain distribution. Increasing the number of CFRP sheet layers leads to a significant increase in the ultimate axial strength and a slight increase in the ultimate displacement. (C) 2020 The Authors.
