Abstract

Design building codes are primary book for structural design engineers to calculate flexural strength. In the design building codes, concrete has important parts. Those are rectangular stress block model and compression strain. This paper evaluates flexural strength of the reinforced concrete beams using six different design approaches like ACI 318-14, AS3600-2009, CAN-A23.3-04, fib Model Code 2010, JSCE 2010 and NZS 3101:2006. Thirty-five test of reinforced concrete beam specimens in this database were tested under four-point monotonic loading. Compressive strength of the concrete is in the range of 18 - 55 MPa and shear span-to-depth ratio is in the range 3 - 5. Based on limited database, the rectangular stress block and compressive strain proposed by fib Model Code 2010 resulted in a mean ratio of the predicted nominal flexural strengths to measure flexural strengths close to 1.0 with a small standard deviation and coefficient of variation. In other hand, the model proposed by CAN-A23.3-04 provides the most conservative estimation.
