(China Academy of Building Research, Beijing 100013, China)Abstract: The provisions of cracking control and detailing measures for prestressed concrete in Code for design of concrete structures(GB 50010-2002), ACI 318-05, Eurocode 2-Design of concrete structures and British standard BS 8110-1 are introduced, then requirements of limiting values of crack width for the maximum allowable spacing of bars at the bottom of beams for prestressed concrete are studied and the recommended design methods for the control of cracking without direct calculation of crack widths are elaborated.
Keywords: prestressed concrete; control of cracking; without direct calculation; crack widths; detailing measures
