Abstract

The design of complex, discontinuous stress trajectory regions (D-regions) is complex in natureand cumbersome to design. The performance of a large scale steel fiber reinforced concrete (SFRC)deep beam with single opening under monotonic loading was tested under controlled conditions. Themain objective of this study was to see if Steel Fiber Reinforced Concrete (SFRC), used as a bettermaterial than reinforced concrete (RC) offered an alternate to the cumbersome and iterative stepsinvolved in strut-and-tie (STM) methodology. Additionally, a similar reinforced concrete (RC) specimenwas tested under the same controlled condition designed with classical strut-and-tie model designmethodology reinforced using conventional steel bars.Material testing was conducted on the materials tested on the large scale specimens to ensurethat the actual material mechanical properties were known for the analysis. Computer Aided Strut and Tie(CAST) software was used to quantify the experimental data obtained from the controlled conditionstesting.The two beams were compared and contrasted throughout the study to indicate the performanceof one beam compared to the other. This study provides information on the viability of using steel fiberreinforced concrete in complex D-regions in structural elements.
