RISVibration Control by Multiple Tuned Liquid Dampers (MTLDs)
Publisher: American Society of Civil Engineers
Abstract: The multiple tuned liquid dampers (MTLDs), which consist of a number of TLDs whose first natural frequencies of sloshing are distributed over a certain range around the natural frequency of a structure, are studied. The ...
Bridge Real-Time Damage Identification Method Using Inclination and Strain Measurements in the Presence of Temperature Variation
Publisher: American Society of Civil Engineers
Abstract: In this paper, a new real-time damage identification method has been presented for bridge structural health monitoring (SHM) considering temperature variation. The method utilizes model-based damage identification that ...
A Flow Visualization Study of Vortex Interaction With the Wake of a Sphere
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A study of the interaction between an initially columnar intake vortex (hereinafter referred to as the primary vortex) and vortex structures in the wake of a single sphere (hereinafter referred ...
SHM-Oriented Hybrid Modeling for Stress Analysis of Steel Girder Bridge
Publisher: ASCE
Abstract: Stress monitoring is always a challenging task in bridge structural health monitoring (SHM) since the measured pointwise stress is not enough for fully reflecting structural conditions. Therefore, a novel hybrid modeling ...
Parametric Variational Principle of Viscoplastic Lubrication Model
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An effective mathematical method to deal with the viscoplastic lubrication model is presented here by applying the parametric variational principle (Zhong, 1985). The plastic slippage of lubricant ...
Distinguishing Stratospheric Sudden Warmings from ENSO as Key Drivers of Wintertime Climate Variability over the North Atlantic and Eurasia
Publisher: American Meteorological Society
Abstract: AbstractStratospheric conditions are increasingly being recognized as an important driver of North Atlantic and Eurasian climate variability. Mindful that the observational record is relatively short, and that internal ...
Camera-Based Vibration Measurement of the World War I Memorial Bridge in Portsmouth, New Hampshire
Publisher: American Society of Civil Engineers
Abstract: Structural health monitoring (SHM) is a method for determining the structural integrity of civil infrastructure elements as a basis for maintenance and repair protocols. This monitoring depends on collecting structural ...
