TENSION-FIELD DESIGN OF TAPERED WEBS.

Abstract

This paper deals with the formulation of design guides for tapered webs based on post-buckling strength. Answers are sought to two specific problems: formulation of necessary modifications to the current AISC ″tension-field formula″ of prismatic girders for the application to tapered webs; and the adequacy of using the AISC tension-field formula for tapered roof beams in frames of the gable type presently encountered in structural engineering practice. The results of this study can be used in the design of tapered roof girders of the gable frames commonly encountered.
