This process is experimental and the keywords may be updated as the learning algorithm improves. 2 are known in direction only (for example, a lamp hanged by two wires). Example 1: Analyze the continuous beam shown below using the force method. These keywords were added by machine and not by the authors. Truss analysis using method of joints is greatly simplified if. It is now recognized that all of the methods of structural analysis are based on either a stiffness approach or a flexibility approach, but this was not widely accepted until the advent of the digital computer which prompted further investigative work. During the latter part of the last century and the early part of this century, methods of structural analysis proliferated. Example: Analyze continuous beam ABCD by slope deflection method and then draw bending moment diagram. By using this technique, damage was identified from the change in displacement responses data. Some programs, such as those devel- oped earlier by, among others, Wang,1 Jennings and Majid,2 and Davies,3 and later by Chen and Sohal,4 perform plastic analysis for frames of. Obviously, certain problems are solved more directly by one method than by the other, but the fact remains that the alternative method is available. The method was tested on a honeycomb composite beam structure. CHAPTER 1 Structural Analysis Stiffness Method 1.1 Introduction Computer programs for plastic analysis of framed structures have been in existence for some time. This is sometimes referred to as the ‘duality’ of structural analysis and it is frequently useful for a student to study the dual problem. The plane truss shown below is statically indeterminate to the second degree The Example The plane truss shown. It is a feature of the analysis of structures that each technique can find expression in an alternative or dual form.
