Experimental evaluation of force analogy method (FAM) by element type

The force analogy method (FAM) is considered as one of the most time-saving and cost-efficient methods for analyzing frames. Through a set of assumptions and restoring forces, FAM analyzes nonlinear frames responses through Hooke�s law. This study evaluates the effect of element type on FAM throug...
