Shear strength of epoxy anchors embedded into low strength concrete

► Cyclic shear tests were conducted on anchors embedded to low strength concrete. ► The obtained results indicate that increasing the anchor diameter have decreased the shear strength. ► A decrease in shear capacity was observed for lower concrete strengths. ► A reduction factor is introduced depending on the bar diameter and concrete strength. ► Establishing an upper limit for the anchor bar diameter in the related standards is proposed.
