RISAdaptive Hermite Distribution Model with Probability-Weighted Moments for Seismic Reliability Analysis of Nonlinear Structures
Publisher: ASCE
Abstract: In this paper, an adaptive Hermite distribution model with probability-weighted moments (PWMs) is proposed for evaluating the extreme-value distribution (EVD) of response, which serves as the basis of seismic reliability ...
Novel Hermite Polynomial Model Based on Probability-Weighted Moments for Simulating Non-Gaussian Stochastic Processes
Publisher: ASCE
Abstract: The Hermite polynomial model based on the first-four central moments of non-Gaussian distribution is widely applied to simulate non-Gaussian stochastic processes due to its simplicity and efficiency. Although a variety of ...
The Nonlinear Time-Varying Response of Dynamic Thermal Tensioning for Welding-Induced Distortion Control
Publisher: The American Society of Mechanical Engineers (ASME)

Record 2011 Spring Flood of the Mississippi River: How Much Nitrate Was Exported from Its Largest Distributary, the Atchafalaya River, into the Gulf of Mexico?
Publisher: American Society of Civil Engineers
Abstract: The Mississippi River Flood of 2011 was a record-breaking flood that required the opening of the Morganza Spillway for only the second time since its completion in 1954. The opening brought a large quantity of nitrogen-rich ...
An Adaptive Mixture of Normal-Inverse Gaussian Distributions for Structural Reliability Analysis
Publisher: ASCE
Abstract: Recovering the probability distribution of the limit state function is an effective method of structural reliability analysis, in which it still is challenging to balance the precision and computational efforts. This paper ...
Single-Pipe Model of Oxygen Diffusion in Unsaturated Cement Pastes: Comprehensive Analysis of Surface, Knudsen, Bulk, Transition, and Water-Curtain Diffusion
Publisher: ASCE
Abstract: One of the most important factors affecting the durability of concrete structures is reinforcement corrosion, which is caused by oxygen concentration. Therefore, it is important to investigate oxygen diffusion in cement ...
