Bilevel Data-Driven Modeling Framework for High-Dimensional Structural Optimization under Uncertainty Problems
Publisher: ASCE
Abstract: Optimization under uncertainty (OUU) is a robust framework to obtain optimal designs for real engineering problems considering uncertainties. The numerical solution for large-scale problems involving millions of ...
New Formulation of Compressive Strength of Preformed-Foam Cellular Concrete: An Evolutionary Approach
Publisher: American Society of Civil Engineers
Reliability-Based Multiobjective Design Optimization of Reinforced Concrete Bridges Considering Corrosion Effect
Publisher: American Society of Civil Engineers
Case Study for Quantifying Flood Resilience of Interdependent Building–Roadway Infrastructure Systems
Publisher: ASCE
Abstract: Resilience is defined as the ability of a system to withstand and recover to a desired level of performance after the occurrence of a hazard. Community resilience has a significant socioeconomic implication for any disaster. ...
NURBS Surface-Altering Optimization for Identifying Critical Slip Surfaces in 3D Slopes
Publisher: ASCE
Abstract: The evaluation of slope stability of a three-dimensional slope requires identifying the critical slip surface with the minimum factor of safety, which is a complex optimization problem. Failure to identify the critical ...
Formulation of Constitutive Viscoelastic Properties of Modified Bitumen Mastic Using Genetic Programming
Publisher: ASCE
Abstract: The objective of this study is to create explicit prediction models for the complex shear modulus (G*) and phase angle (δ) of bitumen mastic fabricated using an evolutionary machine learning approach. The dynamic shear ...
Spline Search for Slip Surfaces in 3D Slopes
Publisher: ASCE
Abstract: A novel method involving the transformation of spline surfaces is introduced to search for the critical slip surface in a three-dimensional (3D) slope, which corresponds to the minimum limit equilibrium method factor of ...
Improving Long-Term Flood Forecasting Accuracy Using Ensemble Deep Learning Models and an Attention Mechanism
Publisher: American Society of Civil Engineers
Abstract: Floods, as major natural disasters, cause massive property destruction and death. Understanding the occurrence time of this event by advance notice helps consider operational flood prevention systems and platforms. Precise ...
Next-Generation Models for Evaluation of the Flow Number of Asphalt Mixtures
Publisher: American Society of Civil Engineers
Abstract: This paper presents the development of next-generation prediction models for the flow number of dense asphalt–aggregate mixtures via an innovative machine learning approach. New nonlinear models were developed to predict ...
