Then solve the external loads to give the actual joint displacements, from which you have to compute redundant forces. Express equilibrium equations, in terms of these displacement.

Consider displacements of joints as unknowns, and.

The displacement-based method is amenable to computer programming and hence we use this in the modern day structural analysis. Equilibrium or Displacement or Stiffness coefficient method

Castigliano’s theorem of minimum strain energy.Ģ.

Method of consistent deformation: Developed by Clerk Maxwell (1864), Otto Mohr (1874) and Muller- Breslau (1886).

(imposed on the formations of the structures). Additional equations are obtained, by considering the geometrical conditions. We use this methods to calculate reactions and internal forces in statically indeterminate structures due to loads and imposed deformations.įirst step is to select the redundant forces as unknowns. This is also known as Flexibility coefficient or Force method. The two basic methods available for analysis of statically indeterminate structure are, but not limited to these. A typical example of a building frame is the reinforced concrete multistory frames. But the building frames are designed in such a way that the beam-column joints stay rigid. We use building frames as the most common structural form.

The types of frame, its configuration in multi-storied frame and degree of indeterminacy. The method of analysis to adopt depends upon the following factors. We can analyze Building frames by various methods. An elastic body is called a structure when a set of loads are applied the elastic body deforms and also the system is set up against the deformation. A structure means a system of connected parts used to support a load.
