assume all structures are composed of frame elements (beams and columns), i.e. internal shear, bending, and axial force may be present. Determine: ns , nsE, nsl, and whether the structure is stable or unstable. For ns , show your work for both the equation method and the "by inspection method" showing interim structures as releases are made.

Matrix Algebra for Structural analysis

Structural analysis is a process in which the effects of different loads and internal forces, acting on structures and their elements are determined. This method of analysis is effective in detecting the failure loads of the structural elements and the design can be altered before commencing the construction process, which ensures proper strength and safety of the structures.
