RISVibration-based Damage Detection of Structures by Genetic Algorithm
Publisher: American Society of Civil Engineers
Abstract: Vibration-based methods are being rapidly applied to detect structural damage. The usual approaches incorporate sensitivity analysis and the optimization algorithm to minimize the discrepancies between the measured vibration ...
Auto-Parametric Vibration of a Cable-Stayed-Beam Structure under Random Excitation
Publisher: American Society of Civil Engineers
Abstract: Auto-parametric vibration of a cable-stayed-beam structure under a random excitation is first studied numerically with emphasis on cable local vibration. A simplified 3-degree-of-freedom model that includes linear as well ...
Evaluation of the Effectiveness of Strengthening Intervention by CFRP on MRWA Bridge No. 3014
Publisher: American Society of Civil Engineers
Abstract: Main Roads of Western Australia has a continuing program of bridge upgrading, to refurbish and strengthen bridges to allow for increasing vehicle traffic and increasing axle loads. A
Stiffness Assessment through Modal Analysis of an RC Slab Bridge before and after Strengthening
Publisher: American Society of Civil Engineers
Abstract: As part of Main Roads Western Australia’s (MRWA) bridge management and bridge upgrading program, MRWA bridge no. 3014 was assessed to evaluate its condition before and after strengthening works with carbon-fiber-reinforc ...
Condition Assessment of Shear Connectors in Slab-Girder Bridges via Vibration Measurements
Publisher: American Society of Civil Engineers
Abstract: The paper presents a field study on condition assessment of the shear connectors in a full slab-girder bridge via vibration measurements. First, a model updating technique is employed to assess the condition of the whole ...
Damage Identification of Shear Connectors with Wavelet Packet Energy: Laboratory Test Study
Publisher: American Society of Civil Engineers
Abstract: Shear connectors are widely used to link the slab and girders together in slab-on-girder structures. Assessment of the integrity of shear connectors is an important issue in the maintenance and health monitoring of such ...
Dynamic Risk Analysis of Deepwater Gas Hydrate Drilling with a Riserless Drilling System Based on Uncertain Dynamic Bayesian Network Model
Publisher: ASCE
Abstract: The riserless drilling system (RDS) is a dual gradient drilling system. Offshore natural gas hydrate (NGH) drilling projects are often subject to various risks due to uncertainty factors (marine environment and complex ...
Dewatering–Induced Building Settlement around a Deep Excavation in Soft Deposit in Tianjin, China
Publisher: American Society of Civil Engineers
Abstract: This case study presents an investigation on building settlement induced by dewatering for a deep excavation constructed in a deposit in Tianjin, China. The excavation site is located in the Tianjin urban center, around ...
