Pushover analysis for flexible and semi‐flexible pile‐supported wharf structures accounting the dynamic magnification factors due to torsional effects

Structural Concrete, 2020
This is a pushover analysis for pile‐supported wharves considering the dynamic magnification factors due to torsional effects. The piles seismic design by deterministic approach is shown accounting plastic hinges and P‐delta effects in 2D/3D mathematical

Lateral load pattern in pushover analysis

Earthquake Engineering and Engineering Vibration, 2003
The 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 ...

The analytical curvature distribution model of columns and mathematical solution for pushover analysis

Earthquake Engineering & Structural Dynamics
The acquisition of a flexural backbone curve for columns primarily relies on finite element analysis and experiments, of which the complexity and high cost are significant challenges. Hence, this study proposes an analytical curvature distribution model (

Pushover Analysis of GFRP Pultruded Frames

Mechanics of Composite Materials, 2015
Results 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

Modal Pushover Analysis for Unsymmetric Buildings

Structures Congress 2005, 2005
The 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 ...

Seismic Damage Detection Using Pushover Analysis

Advanced Materials Research, 2011
Inter-story drift ratio is a general damage index which is being used to detect damaged stories after severe ground motions. Since this general damage index cannot detect damaged elements also the severity of imposed damages on elements, a new real-time seismic damage detection method base on artificial neural networks was proposed to overcome this ...

Dynamic-Based Pushover Analysis for Two-Way Plan-Asymmetric Buildings under Bidirectional Seismic Excitation

, 2020
A dynamic-based pushover procedure for two-way plan-asymmetric buildings (DPTPA) is proposed based on performing two nonlinear static analyses along the principal directions of the structur...

Applicability of Modal Pushover Analysis on Bridges

Advanced Materials Research, 2011
Taking 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 ...
