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. ...
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 ...
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 ...
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 ...
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 ...
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 ...
