Incremental modified pushover analysis
The Structural Design of Tall and Special Buildings, 2008AbstractThe recently developed Incremental Dynamic Analysis (IDA) requires nonlinear time history analyses at different levels of intensity of an ensemble of ground motions, which is time‐consuming due to the high computational efforts involved. In the current study, a simplified method named as Incremental Modified Pushover (IMP) is developed and ...

Pushover Analysis: Proposals for Modification
Structural Engineering International, 2009Estimating earthquake-induced response, both in elastic and post-elastic range, with adequate precision is a major challenge to performance-based seismic design. A simple effective method known as pushover analysis amenable to be exercised in routine design is gaining popularity in the recent times.

Applicability of Modal Pushover Analysis on Bridges
Advanced Materials Research, 2011Taking one irregular continuous bridge as an example, modal pushover analysis (MPA) has been conducted to judge whether it would be applicable for seismic analysis of irregular bridge structures. The bridge’s seismic demand in the transverse direction has been determined through two different methods, inelastic time history analysis (ITHA) and MPA ...

Lateral load pattern in pushover analysis
Earthquake Engineering and Engineering Vibration, 2003The seismic capacity curves of three types of buildings including frame, frame-shear wall and shear wall obtained by pushover analysis under different lateral load patterns are compared with those from nonlinear time history analysis. Based on the numerical results obtained a two-phase load pattern; an inverted triangle (first mode) load pattern until ...

Pushover procedure for seismic analysis of buildings
Progress in Structural Engineering and Materials, 1998AbstractThis article is a state‐of‐the‐art review of the simplified inelastic analytical procedure commonly referred to as the ‘pushover analysis’ to estimate the seismic response of buildings. The basic steps of a pushover analysis are outlined. The choices available to users in each step are discussed and past studies involving the pushover procedure

Modal Pushover Analysis for Unsymmetric Buildings
Structures Congress 2005, 2005The modal pushover analysis (MPA) procedure for estimating seismic demands is extended to unsymmetric-plan buildings. In the MPA procedure, the seismic demand due to individual terms in the modal expansion of the effective earthquake forces is determined by nonlinear static analysis using the inertia force distribution for each mode, which for ...

Pushover Analysis of GFRP Pultruded Frames
Mechanics of Composite Materials, 2015Results of a pushover analysis of GFRP pultruded frames aimed at the evaluation of their overall ductility are presented. It is assumed that the dissipation capacity of the frame structures is concentrated in joints due to their nonlinear behavior induced by progressive damage, while a brittle-elastic behavior is assumed for frame members. A two-storey

STATE-DEPENDENT SEISMIC FRAGILITY VIA PUSHOVER ANALYSIS
2020Earthquakes are clustered in space and time. This means that structures in seismically active regions can be subjected to multiple consecutive instances of base acceleration, with insufficient in-between time for repair operations to take place. In such situations, buildings may experience degradation of their lateral-force-resisting capacity due to ...
