Webb7 okt. 2024 · 1) Wind Loading. Braced frames with X-bracing subject to wind loading have been examined by André Picard and Denis Beaulieu (1987, 1988). They concluded that the effective length of the compression diagonal is half the full member length (i.e. K = 0.5). However, the study was based mostly on elastic buckling and on the assumption that no … WebbA development was undertaken to demonstrate the feasibility of using computer methods to calculate the effective length factors of elastically restrained beam‐columns. Three theoretical models for elastically restrained beamcolumns were derived to characterize the structural behavior of various types of elements used in offshore structures, such as …
