Abstract

This paper describes shear capacity and failure mechanisms of reinforced concrete push-off specimens strengthened with deep embedded FRP/Steel bars across a shear plane. An emphasis was put on the minimum bar anchorage lengths required for effective shear transfer. For this purpose, ten initially uncracked push-off specimens were designed to fail along a known shear plane. Four specimen types were strengthened using CFRP, GFRP and steel bars of 10mm diameter respectively. These bars crossed the shear plane at an angle of 450 and 900 with varying anchorage lengths and constant reinforcement ratio of 0.26% in order to examine their effect on shear friction capacity more closely. Therefore, this paper reports on the test results, and on their significance in being able to apply Deep Embedment strengthening techniques to concrete structures.
