The objective of the study is to investigate the performance and economy of nine different bracing systems in a specified plane frame. An automated design program, which is described in two appendices, is used to size the members in the frames. The results show the relative economy and performance of the various bracing systems. Results concerning stiffening of frames to reduce wind drift, portal and cantilever approximate analysis methods and bracing performance during gravity loading are also presented and discussed.technical reportsengCopyright and other restrictions may apply.
