Modal Pushover Analysis for Unsymmetric Buildings
Structures Congress 2005, 2005The 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 ...

Applicability of Modal Pushover Analysis on Bridges
Advanced Materials Research, 2011Taking 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 ...

Modal-Pushover-Based Ground-Motion Scaling Procedure
Journal of Structural Engineering, 2011Earthquake engineering is increasingly using nonlinear response history analysis (RHA) to demonstrate the performance of structures. This rigorous method of analysis requires selection and scaling of ground motions appropriate to design hazard levels. This paper presents a modal-pushover-based scaling (MPS) procedure to scale ground motions for use in ...

Energy-Based Modal Pushover Procedure for Asymmetric Structures
Advances in Structural Engineering, 2010Energy-based seismic evaluations of structures can give clear illustrations of seismic demands made upon structures. This paper presents a 3-dimensional energy-based modal pushover analysis (3D EMPA) method with equivalent three degree of freedom (ETDOF) system and equal-displacement rule. The lateral-rotational coupled effect on structures asymmetric

An adaptive modal pushover procedure for asymmetric-plan buildings
Engineering Structures, 2012An innovative single-run adaptive modal pushover procedure based on the modal story shear and torque has been developed for seismic assessment of asymmetric-plan buildings. In which the load pattern consists of the lateral forces and torques which are derived from the instantaneous combined modal story shear and torque profiles in each step.
