Implementation of Reduced-Order Modeling for Time-History Analysis of Hysteretic Structures Equipped with Seismic Protective Devices
Publisher: ASCE
Abstract: Reduced-order models (ROMs) can provide computationally efficient approximations of the response of finite element models (FEMs). Recent studies have examined the explicit calibration of hysteretic, multi-degree-of-freedom ...
Computationally Efficient Adaptive Design of Experiments for Global Metamodeling through Integrated Error Approximation and Multicriteria Search Strategies
Publisher: ASCE
Abstract: Gaussian processes (GPs) are a popular technique for global metamodeling applications. Their objective in such settings is to establish an efficient and globally accurate approximation of the response surface of computationally ...
Efficient Evaluation of Sobol’ Indices Utilizing Samples from an Auxiliary Probability Density Function
Publisher: American Society of Civil Engineers
Abstract: A sample-based evaluation of Sobol’ sensitivity indices is discussed in this paper relying on Kernel Density Estimation (KDE) for achieving computational efficiency. The foundation of the approach is the definition of an ...
Reliability-Based Design Using Two-Stage Stochastic Optimization with a Treatment of Model Prediction Errors
Publisher: American Society of Civil Engineers
Abstract: Design problems that involve optimization of the reliability of engineering systems are the focus of this paper. Methodologies are discussed applicable to problems that involve nonlinear systems and a large number of ...
Cost of Safety: Holistic Analysis of Market-Based Solutions for Housing in Haiti
Publisher: ASCE
Abstract: Access to affordable and safe housing represents a critical challenge for many low- and middle-income countries. Technical and economic constraints frequently lead aspiring homeowners in these countries toward informally ...
Robust Stochastic Design of Linear Controlled Systems for Performance Optimization
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This study discusses a robust controller synthesis methodology for linear, time invariant systems, under probabilistic parameter uncertainty. Optimization of probabilistic performance robustness for ...
Empowerment Model for Sustainable Residential Reconstruction in Léogâne, Haiti, after the January 2010 Earthquake
Publisher: American Society of Civil Engineers
Abstract: It is estimated that more than 300,000 people were killed in the January 2010 earthquake in Haiti, hundreds of thousands more were injured, and approximately 1.3 million people were left homeless due to the failure of the ...
Reliability-Based Performance Objectives and Probabilistic Robustness in Structural Control Applications
Publisher: American Society of Civil Engineers
Abstract: A reliability-based structural control design approach is presented that optimizes a control system explicitly to minimize the probability of structural failure. Failure is interpreted as the system’s state trajectory ...
A New Adaptive Rejection Sampling Method Using Kernel Density Approximations and Its Application to Subset Simulation
Publisher: American Society of Civil Engineers
Abstract: In stochastic analysis of engineering systems, the task of generating samples according to a target probability distribution involving some performance function of the system response often arises. This paper introduces ...
Numerical Exploration of the Shielding Effect of Vegetation on Nearshore Structures under Wave Run-Up Loading
Publisher: American Society of Civil Engineers
Abstract: Overland flow from inundation events (IEs) such as hurricanes or tsunamis produce destructive loading conditions on nearshore structures. The magnitude of this loading and its associated impact can be substantially reduced ...
