Preliminary assessment of fire damaged reinforced concrete structure and steel truss. Malaysian Journal of Civil Engineering, 29 (2). pp. 195-204. ISSN 1823-7843 (2017)
Abstract
The assessment of fire damaged structure is an area which considered new and have little practical experience in Malaysia. In this study the objective are to determine the concrete strength and the ultimate strength of steel truss and weight loss of the steel after exposure to fire. Non-destructive and destructive test has been tested in this study. Rebound hammer test had been done to determine the strength of the concrete beam while tensile test and corrosion test both have been done by taking samples from the steel purlin. The test conducted in this study follows the BS EN 10 002: Part 1: 1990, ISO 6892-1and ASTM G1-90. The results from rebound hammer test, the compressive strength of the concrete beam is between 40 ± 4 N/mm² while the average ultimate strength of steel truss is between 412 N/mm² to 434 N/mm². Meanwhile, for the corrosion test, when steel0.17%. This testing shows that steel has loss, its mechanical properties due to exposed to elevated temperature. By conducting a non-destructive test for concrete and destructive test for steel it shows to be practical and useful in evaluating the fire damaged reinforced concrete structure and steel truss.
