| Abstract | Experimental data were utilized to investigate the effect of steel fibers on the shear strength of a lightweight concrete beam. Prior tests of steel fiber-reinforced lightweight concrete (SFRLC) beams or smallscale concrete mockups were reviewed. Only two large-scale test programs on SFRLC beams are available to date. The variables studied in these programs included the shear span-to-depth ratio and steel fiber volume fraction. The addition of steel fibers with steel fiber volume fractions of 0.5% to 0.75% increased the shear strength by roughly 25% to 45%. It is also found that the shear-to-depth ratio adversely affected the shear strength. Several models for the shear strength of steel fiber-reinforced concrete beams were evaluated using the re-assessed data to evaluate the shear strength of the SFRLC specimens. Finally, design shear strength equations for SFRLC beams without stirrups have been proposed based on the calibration results. |
