Webcompressed simply supported (pin-ended) columns. Indeed, the (compressed) end rigid links may be viewed as “sway pin-ended columns”, which means that they (i) exhibit null flexural stiffness and, thus, (ii) contribute only to the column overall geometric stiffness − i.e., they have a destabilizing effect on the column flexural (in-plane ... WebFor a column with pinned ends, we have the following conditions: 1. Force P that is applied through the centroid of the cross section and aligned with the longitudinal axis of the column. 2. Force P is guided such that P is always aligned with the pin joints 3. Both ends of the beam are free to rotate about one or more axes.
