Abstract
A method is presented that allows a second order analysis to be performed using a first order computer program, without iteration. Equations of equilibrium are based on the deflected shape of the structure. Computer input for the second order analysis is exactly the same as it is for a first order analysis, except one extra member (a piece of ‘negative’ bracing) is required for each storey. The frame may be braced or unbraced, but must be rectangular.Keywords
