Finally, the chapter discusses the advantages and disadvantages of statically indeterminate structures compared to statically determinate structures. It then describes how to calculate the degrees of static indeterminacy of trusses, frames, beams and crossbeams and also describes the principle of superposition of effects. Next, the chapter then classifies the statically indeterminate structural analysis methods into two categories: the method of forces or flexibility and the method of displacements or rigidity. It is called externally statically indeterminate if the number of support reactions exceeds the number of independent equations. The static indeterminacy of a structure can be internal, external or internal and external simultaneously.

The purpose of structural analysis is to determine the support reactions and the variation of internal actions in the elements of a statically indeterminate structure. It then illustrates these analysis methods. © 1997 John Wiley & Sons, Ltd.This chapter first gives a general introduction to the methods of analyzing statically indeterminate structures. An overview of the integrated force method analysis code (IFM/ANALYSERS) is provided in the appendix. Analyze two span continuous beam ABC by slope deflection method.Then. The usefulness of animation in design optimization is illustrated considering the spacer structure component of the International Space Station as an example. reactions & draw the bending moment & shear force diagram. Animation of stresses and displacements, which have been developed successfully through the IFM analyzers, is illustrated in several examples along with a brief introduction to IFM dynamic analysis.

The reformulated method of forces, which in the literature is known as the Integrated Force Method (IFM), became the analyser of choice for the development of stress-mode animation because stresses are the primary unknowns of its dynamic analysis.

Structural Analysis Lecture 9 Example 4 (Solution) Principle of superposition By inspection the truss is indeterminate to the first degree. This paper attempts to complete this valuable visualization tool by augmenting stress-mode animation to the existing art. Structural Analysis Lecture 9 33 Force Method of Analysis: Trusses Example 4 Determine the force in member AC of the truss shown. At the present time only displacement-mode animation is available through the popular stiffness formulation. Dynamic animation of stresses and displacements, which complement each other, can be a useful tool in the analysis and design of structural components.
