Modal Filter Based Structural Control of a Highway Bridge
An Adaptive Modal Filter (AMF) algorithm is developed which uncouples complicated multi-mode structural dynamic response into simple single-mode response. The application to active structural...
Instrumented Buoy Network Response to Ocean Swell
The National Data Buoy Center has an extensive network of more than 20 moored buoys along the west coast of North America And in the Eastern North Pacific Ocean. The network ranges from...
A Sonobuoy-Sized Expendable Air-Deployable Directional Wave Sensor
Obtaining wave information from small expendable air-deployable buoys is important for numerous military operations, civilian applications, and research purposes. Such buoys may be deployed...
Buoy Directional Wave Measurements Using Magnetic Field Components
Directional wave data can be estimated using the heave, pitch and roll motion of a discus buoy, which are conventionally measured by a pitch-roll sensor. To reduce the size and cost, this...
On Hurricane-Generated Seas
Two different situations in the relationship between wind speed and sea severity during hurricanes (and tropical cyclones) are clarified from analysis of measured data obtained by NOAA...
Estimation of Directional Spectra by ML/ME-Methods
The paper discusses the statistical Maximum Likelihood (ML) and Entropy (ME) methods for estimation of directional wave spectra. A combined ML/ME method is derived, and a reduced version...
Evolutionary Fourier Analysis of Wave Data
A new method is presented for analyzing nonstationary water level height time series. The usual assumption of pseudo-stationary intervals is avoided and the wave spectra can be changing...
Design Waves and Wave Spectra for Engineering Applications
Thirteen years of hourly wave data measured at two of the National Data Buoy Center's (NDBC) buoy stations, one located in the northeastern Pacific and the other located in the northwestern...
Graphical-Based Productivity Transient Investigation Using DISCO
Construction operations involve complex resource interactions and are typically performed in the field with exogenous factors such as inclement weather conditions and equipment breakdowns....
An Interactive Computer Code for Generations of Artificial Earthquake Records
A new interactive computer code is presented in this work for the calculation of artificial earthquake records that comply with any arbitrarily specified target response spectra or power...
The Use of Piezoelectric Film in Cavitation Research
A research program was conducted at the St. Anthony Falls Hydraulic Laboratory to investigate impulse pressures caused by the collapse of transient cavitation bubbles. The impulse pressures...
Laplace Valve Stroking for Complex Piping Systems
LaPlace valve stroking to control water hammer is applied in complex piping systems with friction and without friction. Two types of system are analyzed. The law of operation of the valves...
Nonlinear Response of SDOF Systems to Intraplate Earthquakes
It is well established that there are characteristics differences between intraplate and interplate earthquakes. A parametric study of SDOF systems indicates that there is also consistent...
Structural Design and Wind Resistance of Fukuoka Tower with T.M.D.
Fukuoka Tower, which was built in 1989, was projected as a monument, a observation tower and a broadcasting antenna with 234m high. In this tower, a Tuned Mass Damper(TMD) was set, in...
Structural Response Using Stiffness Decoupler
The structural properties of a new stiffness decoupler developed by Hu, Kirmser and Swartz at Kansas State University, and its applications as an energy absorber and a device to isolate...
Floor Response Spectra Analysis Including Correlations of Multiple Support Motions
This paper deals with the response spectrum analysis method of the secondary structures including the correlation effects between nonuniform support excitations. Based on the random vibration...
