IMPAβ: Incremental Modal Pushover Analysis for Bridges [PDF]

Applied Sciences, 2020
In the present study, the incremental modal pushover analysis (IMPA), a pushover-based approach already proposed and applied to buildings by the same authors, was revised and proposed for bridges (IMPAβ). Pushover analysis considers the effects of higher

Incremental Modal Pushover Analysis (IMPA) for bridges [PDF]

, 2021
In recent years, many research activities were undertaken to develop a reliable and practical analysis procedure to identify the safety level of existing structure. There are many literatures available on the seismic evaluation procedures of buildings using nonlinear static analysis (pushover) instead of performing, as in the well known incremental ...

Bidirectional Pushover Analysis of Irregular Structures

Journal of Structural Engineering, 2014
AbstractPushover analysis is one of the most-used nonlinear static procedures for the seismic assessment of structures; therefore, nowadays it is extensively used by practicing engineers for the seismic analysis of virtually every type of building. This paper proposes a bidirectional pushover analysis (BPA) method to overcome the limitations of current

Modified generalized pushover analysis for estimating longitudinal seismic demands of bridges with elevated pile foundation systems

Latin American Journal of Solids and Structures
In longitudinal multi-mode pushover analysis of bridges with elevated pile foundation systems, the inelastic contributions of the second mode cannot be neglected. Generalized pushover analysis cannot be applied directly in this condition.

An Energy Based Adaptive Pushover Analysis for Nonlinear Static Procedures [PDF]

Civil Engineering Infrastructures Journal, 2016
Nonlinear static procedure (NSP) is a common technique to predict seismic demands on various building structures by subjecting a monotonically increasing horizontal loading (pushover) to the structure.

A Non Linear Analysis Of Structure: Pushover Analysis

, 2016
In this paper we propose to assess seismic performance of a six stored reinforced concrete building designed according to the Moroccan seismic code RPS2000[1]. the building is residential and has a reinforced concrete frame structural system. In the first time a set of dynamic analysis are carried out to compute dynamic properties of the building ...

Effectiveness of modified pushover analysis procedure for the estimation of seismic demands of buildings subjected to near-fault ground motions having fling step [PDF]

Natural Hazards and Earth System Sciences, 2013
Near-fault ground motions with long-period pulses have been identified as being critical in the design of structures. These motions, which have caused severe damage in recent disastrous earthquakes, are characterized by a short-duration impulsive motion ...
