In the foreign countries there are not only design guidelines but also standards for testing FRP materials. These codes do not recommend using FRP bars in compressive members, such as columns. But the compressive strength shouldn’t be neglected according to those design codes. In our country the standards for FRP testing and design codes are just in the process of development.This paper contains the results of a compression testing of GFRP and BFRP with different configurations. The proposed height of the specimen was 1d, 3d and 5d. The results of the tests and failure mechanisms of the samples are discussed. The author also gives strain distribution in dependence with the specimen type. The conclusions and proposals for the use of FRP reinforcement in compression are offered. One of the main conclusions is that with the height increase the compressive strength also increases, while the strain decreases.Basing on the survey results the ratio of tensile strength to compressive strength and the ratio of compressive elasticity modulus to tensile elasticity modulus are given. |
