Abstract: The paper reports on the application of steel fibre reinforced concrete (SFRC) in arch ribs subjected to static and fatigue loading. A theoretical study was carried out prior to the experimental programme in order to identify the worst loading conditions for use in the experimental study and to identify the locations for instrumentation at the two additional hinges formed in the arch at failure. Two types of arch ribs were used in the study: solid rectangular sections (300mm wide x 145mm deep) and U-shaped channel sections (with overall dimensions of 300mm wide x 250mm deep). Four solid sections and five channel sections were used in the study. Initial test results were obtained under static loading and thereafter each section type was subjected to fatigue loading. The fatigue tests were interrupted at regular intervals in order to carry out static tests corresponding to the minimum, mean and maximum loads in the fatigue test. Deflections and crack opening deformation were monitored in this way throughout the fatigue test. The SFRC arch ribs were shown to provide good static and fatigue performance and further work is in progress to expand this work and their areas of application.
