Experimental Data Have to Decide Which of the Nonprobabilistic Uncertainty Descriptions—Convex Modeling or Interval Analysis—to Utilize
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This study shows that the type of the analytical treatment that should be adopted for nonprobabilistic analysis of uncertainty depends on the available experimental data. The main idea is based ...
Ultrasonic Shear Wave Reflection Method for Direct Determination of Porosity and Shear Modulus in Early-Age Cement Paste and Mortar
Publisher: American Society of Civil Engineers
Abstract: An ultrasonic technique for measuring reflection of horizontally polarized shear (SH) waves at different angles of incidence from early-age hydrating mortar and cement paste is described. Measurements from mortar with ...
Wind Tunnel Mach Number Prediction Based on the Pruned Feature Subsets Ensemble Method
Publisher: American Society of Civil Engineers
Interval Analysis Method for Structural Damage Identification Based on Multiple Load Cases
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Based on the measured static displacements, an improved interval analysis technique was proposed for the structural damage identification. Due to the scarcity of uncertain information, the ...
Comparisons of Probabilistic and Two Nonprobabilistic Methods for Uncertain Imperfection Sensitivity of a Column on a Nonlinear Mixed Quadratic-Cubic Foundation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Two nonprobabilistic set-theoretical treatments of the initial imperfection sensitive structure—a finite column on a nonlinear mixed quadratic-cubic elastic foundation—are presented. The minimum ...
Multivariate Coupling Sensitivity Analysis Method Based on a Back-Propagation Network and Its Application
Publisher: American Society of Civil Engineers
Abstract: Sensitivity analysis is a technique for quantitatively analyzing the variation in a dependent variable caused by each independent variable. In this study, a global sensitivity analysis method is proposed that is suitable ...
Prediction of Urban Domestic Water Consumption Considering Uncertainty
Publisher: ASCE
Abstract: Quantitative predictions of urban domestic water consumption are of great significance for the planning and management of water resources. Aimed at the uncertainty in the process of water consumption forecasting, the kernel ...
