Comparative study nonlinear static pushover analysis and displacement based adaptive pushover analysis method

International Journal of Structural Engineering, 2018
A major challenge in performance-based earthquake engineering is to develop simple and practical methods for estimating the capacity level and seismic demand on structures by taking into account their inelastic behaviour instead of complicated nonlinear time history analysis.

Can a drawover vaporizer be a pushover?

Anaesthesia, 1994
Summary Bench testing was carried out to establish whether the vapour output from an OMV50 vaporizer, as used in the Triservice apparatus, differs according to whether the carrier gas is either drawn or pushed through the vaporizer.

Pushover Analysis: Proposals for Modification

Structural Engineering International, 2009
Estimating 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.

Incremental modified pushover analysis

The Structural Design of Tall and Special Buildings, 2008
AbstractThe 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 ...

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 ...

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 ...

Multimodal Pushover Analysis for R.C. Bridges

Applied Mechanics and Materials, 2015
In recent years, Italian technical-scientific community has increased its interest on the evaluation of the seismic response of existing structures. Among this wide range of structures, reinforced concrete bridges stand out for their strategic relevance and technical complexity.

Investigation on the Accuracy of Pushover Procedures for SDOF

Advances in Structural Engineering, 2013
The pushover analysis technique is mostly used in the performance-based design of structures and it is favored over nonlinear time-history analysis because of its lower computational cost. However, the accuracy of pushover is not well understood. With this problem in mind, the statistical relationship between the maximum displacement of nonlinear time ...

Pushover procedure for seismic analysis of buildings

Progress in Structural Engineering and Materials, 1998
AbstractThis 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

ON THE DISTRIBUTION OF LATERAL LOADS FOR PUSHOVER ANALYSIS [PDF]

, 2008
Two new simplified adaptive load patterns for pushover analyses are proposed, able to provide an accurate and on safe side assessment of the actual non linear dynamic response, by enveloping the results provided by using the two load vectors. Initially it will be shown how the input modelling can affect the assessment of the response parameters in Non ...
