Design specifications for the time-dependent behaviour of composite steel-concrete structures

Abstract

This chapter deals with the long-term behaviour of composite members and structures used for building and bridge applications and provides a review of the relevant international serviceability limit state design methodologies, with particular focus given to the European, Australian and New Zealand, and American specifications. The first part of the chapter introduces the deflection limit requirements specified in design procedures for satisfying the serviceability limit state conditions. This is followed by a review of the design procedures recommended in the specifications for composite slabs, beams, and columns. Particular attention is devoted to reviewing design methodologies for the calculation of the displacements, for detailing, and for control of concrete cracking.
