原始语种摘要: It is well known that confinement introduced by CFRP (Carbon Fiber Reinforced Polymer) jackets highly increases the ultimate compressive strength and ductility of concrete. Various experimental research programs have been proposed to express the increase in strength and strain by the use of CFRP jackets, but, in the majority of cases, the additional effects of reinforcing elements, like ties or spirals, have not been analyzed very well. This paper provides the investigations on wrapped short concrete columns with and without ties and spirals. In an extensive research program the volumetric ratio of the CFRP jacket and the ratio of transverse reinforcement were varied. Thereby, columns with different geometrical shape, different CFRP thickness, and with different transverse reinforcement...
