The analysis of statically indeterminatestructures, using the force and displacement methods, areconsidered as exact, as in such an analysis, the conformityand equilibrium conditions of the structure are satisfiedexactly. However, the results of such a particular analysisrepresent the particular structural response only to thepurpose up to which the model of the structure representsthe particular structure. These methods are often reliablyused, given as accurate as possible analytical model of thestructure is employed within the analysis. But due to thedifficulties related to exact analysis like time consumingcomputations of deflections and finding solutions ofmultiple equations, further complicated by the relativesizes of the members of the structure, the preliminarydesigns of indeterminate structures are often supported bythe results of approximate analysis. Approximate analysisbecomes very convenient to use within the planning phaseof projects, when various alternative designs of thestructure are considered and compared with reference toeconomic aspects. This text aims to match the results fromthe 2 methods obtained with numerical analysis on a framestructure. The approximate methods are expected to yieldresults within 25% of the precise solutions.
