Shear transfer in lightweight concrete

This research studied the shear transfer in lightweight aggregate concrete and foam concrete. Fourteen series of pre-cracked push-off specimens, made with different concrete strengths were tested. The effects of concrete strength and shear reinforcement parameters on shear transfer behaviour, including shear transfer strength, were analysed. Almost all the specimens failed as a result of slippage along the shear plane. Together with experimental results obtained from a literature review, general formulas for shear transfer strength for reinforced lightweight concrete are also proposed.
