1 de nov. de 2021 · A new enhanced multi-modal pushover procedure based on the structural dynamic theory with a straightforward and easy-to-use algorithm is developed in this study for estimating the structural demands.
1 de may. de 2020 · The present paper evaluates the effectiveness of two multi-mode non-adaptive pushover methods, including the energy-based MPA method and the direct vectorial addition (DVA) based pushover method in predicting the curvature ductility demands of four tall single-column piers.
15 de jun. de 2020 · The presented method, which has been named the multi-mode adaptive displacement-based pushover (MADP) analysis procedure, estimates the seismic demands of buildings by using several multi-stage modal pushover analyses.
23 de dic. de 2023 · The improved modal pushover analysis (IMPA) method advances beyond the standard modal pushover analysis (MPA) by incorporating the redistribution of inertia forces following the yielding of structures, a significant deviation from MPA’s invariant multi-mode lateral load patterns.
22 de nov. de 2023 · In this paper, we propose a simplified operational method for the calculation of the α -factors and the evaluation of the pushover load pattern \ (\underline {Q}\) of step (3), when the load pattern is defined to maximize a given scalar quantity of interest \ (F\).
23 de sept. de 2020 · In this method, the structure is pushed in successive static steps with a known pattern of lateral forces toward a target displacement at its roof. This procedure, which is called the conventional pushover analysis (CPA), benefits from the simplicity of the linear methods and accuracy of the nonlinear approaches.
23 de dic. de 2023 · pushover analysis methods that employ first modal inertial or invariant single load vectors, detailing their methodology and significance. • Section4: a study of pushover analysis with invariant multi-mode vectors.
