RISDamage Identification in Frame Structures Based on FE Model Updating
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper proposed a practical damage detection method for frame structures based on finite element model-updating techniques. An objective function is defined as minimizing the discrepancies ...
Structural Damage Identification Based on Quadratic Optimization of Objective Functions with Modal Residual Force and Weighting Strategy
Publisher: ASCE
Abstract: Structural damage identification (SDI), an important issue in the field of structural health monitoring (SHM), is usually converted into a constrained optimization problem. However, the conventional objective functions ...
Cloud Computing-Based Time Series Analysis for Structural Damage Detection
Publisher: American Society of Civil Engineers
Abstract: The structural damage detection (SDD) and on-line integrity assessment is one of the fundamental objectives in the field of structural health monitoring (SHM). Unfortunately, some of the existed SDD methodologies are ...

Identification of Multi-Axle Vehicle Loads on Bridges
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Both the time domain method (TDM) and frequency-time domain method (FTDM) are introduced and modified for the indirect identification of multi-axle vehicle loads from the bending moment responses ...
Weighted Transmissibility Assurance Criterion for Structural Damage Detection
Publisher: ASCE
Abstract: Transmissibility function (TF) is a useful damage indicator for effective structural damage detection (SDD) under unknown external excitations. However, TF is not sensitive enough to structural damage under measurement ...
Onsite Identification of Moving Vehicle Loads on Multispan Continuous Bridge Using Both Dictionary Expansion and Sparse Regularization
Publisher: ASCE
Abstract: Moving force identification (MFI) plays an important role in monitoring moving vehicle loads acting on a bridge, which has attracted great attention in recent years. Although many MFI methods have been proposed, their ...
Analysis of the Effect of Beam Divergence Angle on Back-Streaming Electron Region in Ion Source for EAST-Neutral Beam Injection
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: During the process of beam extraction in positive ion source under high voltage region, a large number of electrons are produced in the gaps of grids. After back-streaming acceleration, these electrons go back to arc chamber ...
Internet-Based Geographical Information Systems System for E-Commerce Application in Construction Material Procurement
Publisher: American Society of Civil Engineers
Abstract: This study combines two luminous areas, geographical information systems (GIS) and E-commerce system, and applies the combined technology in the business of construction material trading. In the era of electronic business, ...
