Single-Run Adaptive Pushover Procedure for Shear Wall Structures

2017
This chapter proposes a new single-run adaptive pushover method for the seismic assessment of shear wall structures. This method offers two main advantages: it does not require decomposing the structure in nonlinear domain and it avoids the pitfall of previous single-run adaptive pushover analyses in utilizing the modal combination in the determination

DEVELOPMENT AND VERIFICATION OF A DISPLACEMENT-BASED ADAPTIVE PUSHOVER PROCEDURE

Journal of Earthquake Engineering, 2004
In this paper, an innovative displacement-based adaptive pushover procedure, whereby a set of laterally applied displacements, rather than forces, is monotonically applied to the structure, is presented. The integrity of the analysis algorithm is veried through an extensive comparative study involving static and dynamic nonlinear analysis of 12 ...

EVALUATION OF CONVENTIONAL AND ADAPTIVE PUSHOVER ANALYSIS II: COMPARATIVE RESULTS

Journal of Earthquake Engineering, 2006
In this paper, the methodology for evaluation of conventional and adaptive pushover analysis presented in a companion paper is applied to a set of eight different reinforced concrete buildings, covering various levels of irregularity in plan and elevation, structural ductility and directional effects.

Adaptive upper-bound pushover analysis for high-rise moment steel frames

Structures, 2019
Abstract In this paper, a new nonlinear static analysis procedure is proposed to assess the seismic performance of tall buildings, which considers both the higher modes effects as well as the progressive changes in the dynamic characteristics of structures during the inelastic response.

An adaptive pushover procedure based on effective modal mass combination rule

Engineering Structures, 2013
Abstract In order to overcome the major drawbacks of conventional pushover methods, researchers have recently been motivated to develop adaptive pushover procedures by which effect of higher modes as well as progressive damage accumulation are taken into account.

Verification of displacement-based adaptive pushover through multi-ground motion incremental dynamic analyses

Engineering Structures, 2009
The present study aims at validating pushover methodologies for RC frame structures through comparison with Incremental Dynamic Analysis (IDA). A large number of simulated response spectrum compatible time-histories has been used to perform incremental dynamic analyses, and results are analyzed in a statistical manner.

A shear–based adaptive pushover procedure for moment-resisting frames

2018
The effects of higher modes are neglected in conventional pushover analysis procedures. Among the improved pushover methods, the adaptive pushover procedures are attractive for their multi-mode capability. In such procedures, the dynamic characteristics of buildings are updated in each stage of analysis consistent with the extent of the non-linear ...

Simplified Seismic Evaluation of Structures Using Adaptive Pushover Analysis

2014
A simplified procedure for evaluating the seismic performance and retrofit of existing low to mid-rise reinforced concrete buildings was first presented by Bracci et al. (ASCE J Struct Eng 123(1):3–10, 1997). The procedure is derived from the well-known Capacity Spectrum Method (Freeman, Prediction of response of concrete buildings to severe earthquake

Adaptive Force-Based Multimode Pushover Analysis for Seismic Evaluation of Midrise Buildings

Journal of Structural Engineering, 2018
AbstractTo consider the effect of higher modes in predicting the seismic responses of midrise buildings, as well as the progressive changes in the dynamic characteristics during the nonlinear analy...

A DISPLACEMENT-BASED ADAPTIVE PUSHOVER FOR ASSESSMENT OF BUILDINGS AND BRIDGES

2006
Estimating seismic demands on structures requires explicit consideration of the structural inelastic behaviour: to this end, the use of nonlinear static procedures, or pushover analyses, is inevitably going to be favoured over complex, impractical for widespread professional use, nonlinear time history methods.
