Abstract:
A method of the analysis of the instantaneous and time-dependent response of composite steel-concrete beams is described. The effects of creep and shrinkage are quantified by the age-adjusted effective modulus method and a relaxation procedure. Linear behavior is assumed. The method was programmed onto a microcomputer and used to obtain the time-dependent response of 65 composite cross sections. Based on the results, a design method is described. The simplicity of the design method is illustrated by an example.
