Glass fibre-reinforced polymer (GFRP) rebars are an alternative to steel rebar for applications prone to corrosion. Limiting the maximum crack width of GFRP-reinforced concrete (RC) elements is one of the main criteria that governs their design. However, there is still limited knowledge of the cracking behaviour and crack width prediction of GFRP RC elements. This paper presents the results of a pilot study on the behaviour of six 1000 mm long reinforced concrete prisms tested under uniaxial tension. The aim of the study is to evaluate the crack development of ribbed GFRP RC structural members. The effects of different variables, such as the concrete prism cross-Sect. (90 × 90 mm and 150 × 150 mm), rebar type (steel and GFRP), and rebar diameter (16 and 19 mm), on the crack width and crack spacing were studied. The experimental results are compared with assumptions of available design codes and guidelines. Moreover, different approaches to predicting crack spacing and crack width are discussed. The results indicate that the reinforcement ratio has a significant influence on the load‒deformation response as well as crack spacing.
