Introduction and Scope

In modeling complex structures, and effective width concept is frequently used to arrive at simple representations, amenable to solution through customary formulas. The following describes the widely used effective width notions in modeling concrete structures, in particular post-tensioned members. It concludes that, depending on the structure and actions at hand, different effective width values and treatments may apply.

The effective width concept is generally used in modeling, when it becomes necessary to assign a portion of the member's cross-section to represent that member's entire response to the applied loading. The substitute cross-section is selected, such as to yield an end-effect analogous to that obtained from a rigorous analysis of the prototype. The effective width approach reduces the computation of a more complex structure into that of a simple beam or frame. The definition and magnitude of the effective width depends on the parameter being analyzed.
