SOME DESIGN CONSIDERATIONS FOR COMPOSITE-FRAME STRUCTURES.

Abstract

Use of these systems requires additional consideration by the structural engineer to reflect the influence of loads and the response of the structure during construction. Adequate attention must be given by the design engineer to clearly define design assumptions on the contract documents and define the responsibility for providing lateral resistance during erection. The erector must be aware of the limitations on frame erection. Several design considerations must be addressed prior to the erection process, including the design storm to use, the effective tributary area over which to apply the wind load, floor diaphragm capability, the removal of any temporary bracing as well as the extent to which it must be removed and drift criteria of the bare frame during erection. This paper represents an evaluation of a number of the requirements which must be considered in the design of composite frame structures.
