Abstract Fragility curves are the primary way of assessing seismic risk for a building with numerous studies focused on deriving these fragility and how to account inherent uncertainty in assessment. This study focuses three-story steel moment frame structure performs assessment using new approach called SPO2FRAG (Static Pushover Fragility) that is based pushover analysis. further compared cont...

In this paper, an incremental nonlinear dynamic inversion (INDI) control scheme is proposed for the attitude tracking of a helicopter with model uncertainties, and actuator delay saturation constraints. A finite integral compensation based on reduction used to compensate delay, can guarantee semi-globally uniformly ultimately bounded tracking. The overall controller separated into rate, attitud...

Abstract Due to technological developments in last decade, new methods of seismic evaluation are use like simulation based, algorithm probabilistic, software based etc. These have enabled researchers move from linear non-linear analysis. Incremental dynamic analysis (IDA) is performance method where a suite ground motions applied structure further scaled particular levels intensity. Seismic fra...

This paper presents a new approach for large-deflection analysis of truss structures employing the Dynamic Relaxation method (DR). The typical formulation for DR has been established utilizing the finite difference technique which is categorized as an explicit method. The special characteristic of the explicit method is its simple algebraic relationships in comparison with complicated matrix op...

Nonlinear behavior of a functionally graded cantilever beam is analyzed under non-uniform hygro-thermal effect. To solve this problem, finite element method is applied within plane solid continua. Total Lagrangian approach is utilized in the nonlinear kinematic relations. Newton-Raphson method with incremental displacement is used in nonlinear solution. Comparison study is performed. Effects of...
