Abstract

The bond behavior between steel and concrete was evaluated under elevated temperatures of 23, 100, 200, 300, 400, 500, and 600 °C with different heating rates. The specimen for testing is the cubical size of 200 × 200 × 200 mm with a rebar placed at the center. The strength of concrete was 25 N/mm2, and different diameters 12 and 20 mm rebars were used. The specimens were heated up to the desired temperature at the interface by following heating rate of 2 °C/min and ISO 834 standard fire curve. Pullout tests were conducted for determining the bond strength and slip between steel and concrete. The bond strength was decreased with increasing temperature and heating rate. The bond strength was decreased very randomly by following heating rate according to ISO 834. © 2020, Springer Nature Singapore Pte Ltd.
