High Temperature Effect on Shear Transfer Strength of Steel Fiber Reinforced Self-Compacted Concrete
Ola Adel Qasim and Abdullah Sinan Ahmed
 
Abstract: Effect of micro steel fiber under exposition to the raised temperatures was studied on shear transformation strength of Self-Compacting Concrete (SCC) experimentally, analytically and numerically by the push-off test. Four groups of 27 testing specimens were performed. Three groups were heated to room temperature, 100, 200, 400, 600 and 800°C. The main adopted variables were fiber percentage with the volume fraction of 0, 1.0 and 2.0% and area of reinforcement which perpendicular to shear plane ρvfy. The experimental results show that steel fiber increases shear strength and higher shear reinforcement retained higher strength values after exposure to temperatures. A newly introduced comparison equation was concluded based on the theoretical and analytical study of experimental data and available data from other researchers based on different variables, compressive strength, fibers factor, area of reinforcement. Proposed equation and finite element results show good agreement for the direct shear strength with experimental results.
