Modal Response Spectrum Analysis 1.2

This application is a method of checking and teaching the Modal Spectrum Response Analysis in a detailed manner with precise results, breaking down the following:

-Mass Matrix
-Stiffness Matrix
-Eigenvalues (ω²)
-Angular Velocities (ω)
-Periods (T)
-Frequencies (f)
-Eigen vectors
-Normalization for each Mode Shape (phi ϕ)
-Proofs of orthogonality
-Participation factor
-Participation percentage for each Mode Shape
-Absolute Displacements (Δ) for each Mode Shape
-Relative Displacements (δ) for each Mode Shape
-Shear Forces (V) for each Mode Shape
-"Square Root of Sum of Squares" (SRSS) for obtaining Absolute Displacements, Relative Displacements, Shear Forces.

Mass and stiffness of each level must be entered, and so the spectral acceleration for each Mode Shape. You also have the option to save the analysis in a text file for later editing in a spreadsheet if desired.
