COMPARISON OF LABVIEW WITH SAP2000 AND NONLIN FOR STRUCTURAL DYNAMICS PROBLEMS

Structural dynamics is a module of structural analysis that encapsulates the behavior of structures subjected to dynamic loadings. The problems of structural dynamics can be categorized as SDOF, MDOF or Continuous systems. LabVIEW is simulating software possessing extensive graphical representation and data acquisition capabilities. It is of particular interest to the engineers working in the general area of structural health monitoring. The graphical user interface and the capability to acquire & process real time data makes it the ideal choice of programming language. In this study, an attempt has been made to develop a dynamic system using a SDOF model in LabVIEW. The results were compared with NONLIN program and SAP2000 software. Parametric study has been done using Newmark β method and the results were plotted for accelerations, velocities and displacements.
