An improved displacement-based adaptive pushover procedure based on factor modal combination rule
Earthquake Engineering and Engineering Vibration, 2014An accurate estimation of the applied load pattern is an essential component in each pushover procedure. Recently, a number of adaptive pushover methods have been proposed in which the effects of the higher modes as well as the progressive changes in the dynamic characteristics of structures are taken into account to compute the applied load pattern ...

A story shear-based adaptive pushover procedure for estimating seismic demands of buildings
Engineering Structures, 2010Abstract In recent years some adaptive pushover methods have been proposed to include the effects of the higher modes and the changes in the vibration characteristics during the inelastic response. However, because of using the quadratic combination rules to combine the modal forces, the changes in the sign of the story components in the higher modes

An Improved Displacement-Based Adaptive Pushover Procedure for the Analysis of Frame Buildings
Journal of Earthquake Engineering, 2014The main purpose of this article is to develop an alternative adaptive pushover method in which multiple inelastic response spectra proportional to the instantaneous ductility ratio of the structure are employed to reflect the actual energy dissipation characteristic of the structure at a given deformation level.

The Structural Design of Tall and Special Buildings, 2015
SummaryNonlinear static procedures are favored tools for practical applications in the structural engineering profession. However, some limitations are associated with them, including their deficiencies to properly reflect higher modal effects and inertial seismic forces fluctuations in their responses. Some different adaptive pushover methods intended

Computation of R Factor for Steel Moment Frames by Using Conventional and Adaptive Pushover Methods
Arabian Journal for Science and Engineering, 2016Response modification factor, R, can be extracted using static pushover method to reduce the time and complication of dynamic analyses. Recently developed modal and adaptive pushover methods account, respectively, for higher mode effects and changes in structure due to gradual damage during analysis. However, previous attempts on extraction of R factor

Adaptive pushover analysis for the seismic assessment of older reinforced concrete buildings.
2000It has been observed in major recent earthquakes that older reinforced concrete buildings experienced more serious damage than newer buildings. This is because they often present many structural deficiencies. To prevent further losses in future earthquakes, the seismic capacity of these older buildings needs to be assessed so that appropriate measures ...

Seismic performance evaluation of steel moment resisting frames using adaptive pushover
2011A multi-objective and multicriteria performance evaluation of steel moment-frame buildings was realized with a combination of the performance criteria both for structural members and for nonstructural components at the different limit state. As an alternative to incremental response history analysis, an incremental non-iterative nonlinear static ...

The proposed research compares traditional and modified pushover approaches in the seismic design of selected hospitals in Hungary. In this study, we will conduct our analysis using advanced analysis software tools such as SAP2000, OpenSees, and AxisVM, and we will provide insights into the relative usefulness of these methodologies in forecasting ...
