Real columns do not have pin-connected ends

WebA 12-ft wooden rectangular column has the dimensions shown. Determine the critical load if the ends are assumed to be pin connected. E = 1.8 (10^3) ksi. Yielding does not occur. … WebTruss joints can be pin connected but they are usually not only because they are very expensive as compared to making the connections rigid. In Timoshenko’s book it is given that the difference of stresses in pin connections and rigid connections in case of truss is negligible. So we use rigid connections without much problem.

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 ...
