Distant Damage-Assessment Method for Multilayer Composite Systems Using Electromagnetic Waves
Publisher: American Society of Civil Engineers
Abstract: In this paper, a damage assessment method for remotely inspecting the near-surface condition of multilayer composite systems is proposed. The method utilizes far-field steady-state electromagnetic waves reflected from the ...
Novel Crash Surrogate Measure for Freeways
Publisher: ASCE
Abstract: In this paper, a disturbance-based methodology was proposed to represent the safety level of a car-following scenario. According to the probabilistic causal model, the following vehicles always take evasive actions to avoid ...
Prediction of Extreme Traffic Load Effects of Bridges Using Bayesian Method and Application to Bridge Condition Assessment
Publisher: American Society of Civil Engineers
Abstract: Due to the aging of transportation infrastructures and the ever-increasing traffic, the condition assessment of bridges has become increasingly important because it provides useful information for bridge management. A ...
State-of-the-Art Review on the Causes and Mechanisms of Bridge Collapse
Publisher: American Society of Civil Engineers
Abstract: This paper is intended to review the main causes and mechanisms of bridge collapse. The common factors resulting in bridge collapse are first reviewed. These factors are classified into two broad categories, namely, natural ...
Bearing Capacity of Two-dimensional Reinforced Composite Foundation
Publisher: American Society of Civil Engineers
Abstract: The bearing performance of both vertically and horizontally reinforced composite foundation formed by horizontal reinforcement settled on top of granular piles, which can restrict the failure of granular piles, was studied. ...
Assessing Initial Stiffness Models for Laterally Loaded Piles in Undrained Clay: Robust Design Perspective
Publisher: American Society of Civil Engineers
Abstract: The hyperbolic p−y curve method is commonly used to design laterally loaded piles. The initial stiffness (K) and the ultimate resistance per pile length (pu) are the two key parameters that are required to determine the ...
Warning Index Associated with Rock Burst in Deeply Buried Tunnels
Publisher: ASCE
Abstract: Rock bursts are disastrous when occurring during the construction of tunnels in a deep underground rock mass, and they occur under two key conditions: energy release from surrounding rocks; and fracture propagation. Based ...
Novel Hybrid Method Based on Advanced Signal Processing and Soft Computing Techniques for Condition Assessment of Timber Utility Poles
Publisher: American Society of Civil Engineers
Abstract: Recently, a variety of nondestructive evaluation (NDE) approaches have been developed for health assessment and residual capacity estimation of timber structures. Among these methods, guided wave (GW)–based techniques are ...
Effects of Hydrologic Conditions and Reservoir Operation on Transboundary Cooperation in the Lancang–Mekong River Basin
Publisher: American Society of Civil Engineers
Abstract: Multiple stakeholders in transboundary river basins would benefit from cooperation, but how and why stakeholders can achieve this cooperation remains difficult to determine. This paper proposes an approach for analyzing ...
Combined Monthly Inflow Forecasting and Multiobjective Ecological Reservoir Operations Model: Case Study of the Three Gorges Reservoir
Publisher: American Society of Civil Engineers
