| Abstract: | Regularities that include load-deflection at mid-span and other related deformation of glass fiber reinforced plastics(GFRP) reinforced concrete beams were summarized through destructive experiments of GFRP reinforced concrete beams and ordinary reinforced concrete beams.According to the finite element model of ordinary reinforced beams,the methods of finite element model to calculate GFRP reinforced concrete beams were discussed where GFRP bar was considered as linear elastic material,then the flexural per... |
