Numerical models for the simulation of the cyclic behaviour of RC structures in...
Varma, Rajendra KumarTese de doutoramento em Estrutural Engenharia ; This work deals with material modelling and numerical implementation for nonlinear finite element analysis of reinforced concrete (RC) structures. Since the behaviour of concrete and steel being crucial for any RC structure under loading, uniaxial cyclic constitutive models for both were implemented in FEMIX, finite element software. Various advanced materials ha...
A model to simulate the cyclic axil compressive behaviour of rc columns confine...
Varma, Rajendra; Barros, Joaquim; Sena-Cruz, José; Ferreira, DéboraIn the present work a constitutive model to predict the cyclic axial compressive behavior of RC columns confined with CFRP is proposed. This model was implemented in a FEM-based computer program, able to simulate the material nonlinear behavior of reinforced concrete frame structures. The performance of the developed model is assessed using results obtained from experimental tests.
CFRP - Confined reinforced concrete elements subjected to cyclic compressive lo...
Ferreira, Débora; Barros, Joaquim; Varma, RajendraThe effectiveness of discrete and continuous CFRP wrapping arrangements for reinforced concrete (RC) short column subjected to monotonic and cyclic compressive loading is assessed in this work. The experimental program is composed of four series of RC columns with discrete wrapping arrangements and one series of full wrapped RC columns. Each series is composed of a monotonic and a cyclic test. Strain gauges wer...
