Approximate Modal Analysis of Bilinear MDF Systems
Publication: Journal of the Engineering Mechanics Division
Volume 106, Issue 2
Abstract
This paper describes two approximate response spectrum/modal analysis methods for dynamic response of hysteretic multi-degree-of-freedon lumped mass structural models subjected to earthquakes. The methods utilize either: (1)Elastic response spectra; or (2)inelastic response spectra. Both procedures are iterative and recognize changes in mode shapes as a function of inelastic deformation in the structural mumbers. Comparison of exact and approximate responses are made for 3 degree-of-freedom and 10 degree-of-freedom shear beam structures with bilinear hysteresis. Input excitation and several structural stiffness and strength parameters are varied.
