Abstract: A method for computing response spectra for bilinear hysteretic systems subjected to earthquake accelerograms is summarized. The technique provides the exact solution to the equation of motion for ground acceleration which ...

Abstract: A method for the computation of response spectra for elastoplastic and bilinear hysteretic systems subjected to strong‐motion earthquake records is described and compared to Newmark's method. The technique provides the ...

Abstract: Approximate methods for the estimation of maximum story drift in elastoplastic multidegree‐of‐freedom (MDOF) shear buildings are examined. The structures considered have fundamental periods in the range of 0.4–4.0 seconds ...

Abstract: The discontinuity in the ground motion arising from the truncation of earthquake accelerograms may produce inaccuracies in the response of long period structures with low damping. The termination of the ground motion at a ...

Abstract: In current practice, design response spectra are normalized by the three peak ground motions. Alternative scaling factors are evaluated to reduce the dispersion encountered in normalized spectral ordinates. The scaling ...

Abstract: The influence of inelastic load-deformation behavior on seismic energy imparted and dissipated is assessed. Stiffness degrading and bilinear hysteretic models are considered. The load-deformation model has a pronounced ...

Abstract: Earthquake design codes require different methods of analysis for regular and irregular structures, but it is only recently that codes have included specific criteria that define irregular structures. In this paper, the ...
