In this lecture, I showed how to analyze an indeterminate truss structure using Matrix Analysis.
My primary reference here are Kassimali and Mcguire.
Further in the lecture, I used SMATH to automate the process of analyzing the structure to show that STAAD and ETABS are simply automating the generation of Structure Stiffness Matrix.
Here, the lecture is about Sway Frame Analysis. We can approximate the analysis of multistory building using just Beam stiffness matrix by assuming no axial deformation will be present thus no need to use the axial part of stiffness matrix.
