Modelling strong seismic ground motion: three-dimensional loading path versus wavefield polarization [PDF]
, 2012 Seismic waves due to strong earthquakes propagating in surficial soil layers may both reduce soil stiffness and increase the energy dissipation into the soil.

, 2020 Nonlinear time history analysis represents the most appropriate structural analysis procedure to accurately analyze seismically base-isolated structures since their dynamic response is typically governed by a system of coupled nonlinear ordinary differential equations of the second order in time.

Development of seismic fragility surfaces for reinforced concrete buildings by means of nonlinear time‐history analysis [PDF]
Earthquake Engineering & Structural Dynamics, 2009 AbstractFragility curves are generally developed using a single parameter to relate the level of shaking to the expected structural damage. The main goal of this work is to use several parameters to characterize the earthquake ground motion. The fragility curves will, therefore, become surfaces when the ground motion is represented by two parameters ...

A Q‐Learning Algorithm to Solve the Two‐Player Zero‐Sum Game Problem for Nonlinear Systems
International Journal of Adaptive Control and Signal Processing, Volume 39, Issue 3, Page 566-581, March 2025.A Q‐learning algorithm to solve the two‐player zero‐sum game problem for nonlinear systems. ABSTRACT This paper deals with the two‐player zero‐sum game problem, which is a bounded L2$$ {L}_2 $$‐gain robust control problem. Finding an analytical solution to the complex Hamilton‐Jacobi‐Issacs (HJI) equation is a challenging task.

A Robust Adaptive One‐Sample‐Ahead Preview Super‐Twisting Sliding Mode Controller
International Journal of Adaptive Control and Signal Processing, EarlyView.Block Diagram of the Robust Adaptive One‐Sample‐Ahead Preview Super‐Twisting Sliding Mode Controller. ABSTRACT This article introduces a discrete‐time robust adaptive one‐sample‐ahead preview super‐twisting sliding mode controller. A stability analysis of the controller by Lyapunov criteria is developed to demonstrate its robustness in handling both ...

Modeling and Seismic Analysis of Buildings with Water Tanks on their Roof [PDF]
مجله مدل سازی در مهندسی, 2007  Abstract  The existence of containers on buildings in large cities with high earthquake risk has caused many damaging problems during past earthquakes. In addition to financial losses, it might induce uncontrolled fire, water cut and local or global

Advanced Engineering Materials, EarlyView.Predicting extreme defects in additive manufacturing remains a key challenge limiting its structural reliability. This study proposes a statistical framework that integrates Extreme Value Theory with advanced process indicators to explore defect–process relationships and improve the estimation of critical defect sizes. The approach provides a basis for
