| This thesis examines the development of seismic design requirements, and the option to use an R = 3 system in low-seismic applications. It considers the impact of bracing connection behavior on collapse resistance in Chevron-configuration braced-frame systems. Results of a survey of design office practices and connection preferences and design requirements are reported, and typical connections are configured based upon these results. Models of those connections are created based upon finite element analysis and available test data, and incorporated into frame analyses to determine the impact of connection deformations on collapse performance. The contributions of frame action due to the strut and tie behavior of the gusset plates also is discussed. |
