STRUCTURAL BEHAVIOR AND DESIGN OF TWO CUSTOM ALUMINUM EXTRUDED SHAPES IN CUSTOM UNITIZED CURTAIN WALL SYSTEMS
The focus of the research in this thesis is on the structural behavior and design of two aluminum “E–type” structural sections that are used in unitized curtain wall systems today. Moment capacities of the two “E-type” sections as one are analyzed by three methods - hand calculations using Minimum Moment Capacity Approach and Total Moment Capacity Approach, the finite element method using ABAQUS program, and via an experimental investigation. A comparison of moment capacities determined using the three methods is presented. Upon the evaluation and comparison of the results obtained by the three methods in this study, the Total Moment Capacity Approach is determined to be an accurate method to predict moment capacities of the two “E-type” structural sections functioning as one structural member and is recommended for the evaluation of moment capacities of complex thin-walled sections and assembled sections to supplement the Specification for Aluminum Structures (2000).
