RISStudying Failure Modes of GFRP Laminate Coupons Using AE Pattern-Recognition Method
Publisher: American Society of Civil Engineers
Abstract: Acoustic emission (AE) monitoring has been identified as one popular technique applicable for damage discrimination in composites. However, because the damage is not directly identified from the AE data, other nondestructive ...

Trajectory Prediction of a Model Rocket Falling into the Towing Tank: Experimental Tests versus Numerical Simulations
Publisher: ASCE
Abstract: The SpaceX company has introduced a reusable first stage rocket that lands on a floating barge. In the event that the first stage rocket falls off the platform, the investigation of landing location on the seafloor may ...
A Drive-By Frequency Identification Method for Simply Supported Railway Bridges Using Dynamic Responses of Passing Two-Axle Vehicles
Publisher: ASCE
Abstract: A drive-by method is proposed to identify the modal frequencies of railway bridges from the dynamic responses of two-axle vehicles. The theoretical closed-form solution and frequency components of the vehicle response are ...
CFD Simulations and Analyses for Bridge-Scour Development Using a Dynamic-Mesh Updating Technique
Publisher: American Society of Civil Engineers
Abstract: A computational fluid dynamics (CFD)-based simulation methodology using a dynamic mesh updating technique is proposed in this study. This method can numerically describe the complicated 3D scour behavior around the piers ...
Using Dynamic Responses of Moving Vehicles to Extract Bridge Modal Properties of a Field Bridge
Publisher: American Society of Civil Engineers
Abstract: The vehicles moving on a bridge excite bridge vibration and can also serve as response receivers because the vehicle dynamic response contains the vibration information of the bridge. A methodology was proposed in a previous ...

Using Acoustic Emission to Monitor Failure Modes in CFRP-Strengthened Concrete Structures
Publisher: ASCE
Abstract: Carbon fiber–reinforced polymer (CFRP) composites have been widely used to repair and strength concrete structures. Nevertheless, the durability and long-term performance of FPR-strengthened structures are still not well ...
Bridge Retrofitting Using FRP-Wrapped Balsa Wood Deck: Experimental Study and Field Evaluation
Publisher: American Society of Civil Engineers
Abstract: A fairly large amount of existing bridges in the United States are in an urgent need of repairing and upgrading. With the increasing application of fiber-reinforced polymers (FRPs), the FRP-based structural system is a new ...
Study on Dynamic Characteristics of an Improved Composite Box Girder with Corrugated Steel Webs
Publisher: ASCE
Abstract: Composite box girders with corrugated steel webs (CBGCSWs) are used worldwide owing to their light self-weight, high efficiency of prestressing application, and reasonable distribution of shear force and bending moment. ...
