STATIC ANALYSIS OF BEAMS:

STIFFNESS METHOD OF STRUCTURAL ANALYSIS:

INTRODUCTION:

Stiffness method or displacement method is an important approach to the analysis of structures .This is an important approach to the analysis of structures. This is used in its basic form for the analysis of structures that are linear and elastic although it can be adapted to non linear analysis. It is generally used for the analysis of statically determinate cases. This method in its basic form considers the nodal displacements of the structures as unknown. The DIRECT STIFFNESS METHOD is a highly organized, conceptually simple approach for the analysis of all types of structures that is easily implemented in the form of a computer aided analysis procedure using a matrix formulation. Amongst the most far- reaching developments in structural engineering has been the ability to analyze automatically almost all types of structures with a high degree of accuracy and at reasonable cost. The availability of digital computer has made this development possible Methods of analysis that could easily be computerized were quickly developed.
