Title: The Impact Of 500 Mpa Steel Reinforcement On The Serviceability Of Concrete Structures
Appears on pages(s):
Abstract:The introduction of 500 MPa steel reinforcement in reinforced concrete structures will lead to larger deflections and wider cracks at the serviceability limit states. When higher strength reinforcement is used, less steel is required to achieve adequate strength in a given situation. This leads to reduced stiffness after cracking at service loads and consequently larger deflections. Smaller quantities of steel also results in higher tensile steel stresses at service loads, and consequently wider cracks. The design for serviceability will therefore become a more critical aspect of structural design. This paper discusses the impact of 500 MPa reinforcement on the serviceability of concrete structures and provides guidance for structural designers. Some recent and relevant changes to AS3600 are also presented and discussed.
