Designing with Grade 500 Steel

A vast majority of concrete design and construction today uses Grade 420 (420 MPa 60 ksi) steel, wit increasing use of Grade 500 (500 MPa, 72.5 ksi). Market forces and construction efficiencies promote the use of higher yield strength longitudinal reinforcement (for example, Grade 500). This reinforcement performs suitably if the elongation and stress requirements match those mentioned in different codes. Presently, Grade 500 (500MPa, 72.5 ksi) steel is available for concrete construction in Bangladesh. The present monograph explains the advantages and disadvantages of grade 500 steel over Grade 420 so that a structural engineer can have adequate knowledge about the effect of Grade 500 steel in reinforced concrete design for an efficient and economical design. The author also aims to provide design engineer with detailed knowledge about the use and behavior of Grade 500 steel in reinforced concrete design. This book is intended especially for the practicing structural engineers, and will also be useful for building officials, educators, and students.
