An on-grade and an elevated specimen were tested and exposed to regular waves, in the Directional Wave Basin (DWB) at Oregon State University, with varying water depths and wave heights to simulate typical wave/surge conditions resulting from landfall hurricanes on low-lying barrier islands such as Hurricane Sandy that impacted the US East Coast in 2012 and Hurricane Ike that impacted the US Gulf Coast in 2008. Several instruments were used in the experiment, including nine wire resistance wave gauges located offshore, eight ultrasonic wave gauges located onshore near the specimens, four acoustic-doppler velocimeters, twelve pressure sensors, four load cells, and four triaxial accelerometers located on the specimens. The data (water depth, wave height, velocity, pressure, force, acceleration) gathered can help engineers and numerical modelers better understand the wave-structure interaction and help in improving design criteria of coastal light wood frame residential structures subjected to hurricane overland surge and wave loading.

Static and Dynamic Structural Characterization Tests of Wave Basin Hydrodynamic Experiments of Scaled Wood Frame Shear-Wall Residential Buildings
Several in-air experimental methods were performed in the Directional Wave Basin (DWB) at Oregon State University for structural characterization (strength, stiffness, frequency, mode shape, and damping) of an on-grade and an elevated light wood-frame coastal residential structure. These include combined lateral load-displacement and free vibration (pluck) tests, ambient vibration, and forced vibration tests. Load, displacement, and acceleration data were collected using load cells, string potentiometers, and accelerometers. These data along with hydrodynamic test data can help engineers and modelers with verification and validation of fluid-structure interaction modeling of coastal residential structures subjected to hurricane overland surge and wave loading.

A small-scale rolling-pendulum (RP) isolation system with gap restrainers was tested under swept-sine surveys (chirp) of varying amplitude. These tests were used to characterize the properties of the experimental small-scale floor isolation system (FIS) that was subsequently installed in a small-scale three-story primary structure (PS). The PS-FIS system was tested under four historic ground motions through shake table testing. These tests were used to assess the coupling between the FIS and the PS. Additionally, cyclic load-displacement tests were run to characterize the response of the shock absorbers used in the FIS. All the data from these experiments have been processed to quantify the performance and characteristics of the PS-FIS and its components, as documented in the data report and in Bin (2021).more » « less

A Computational Fluid Dynamic (CFD) model study of wave and structure interactions on an elevated residential building under various air gap and surge/wave conditions was performed using the olaFlow, an open-source program using the OpenFOAM (Open-source Fields Operation And Manipulation) platform. The numerical model results, including free surface elevation, wave velocity, and vertical pressures on the underside of the elevated structure, showed a good agreement with the measured time-series data from the 1:6 scale hydraulic experiment (Duncan et al., 2021). The numerical simulations were used to extend the physical model tests by computing the vertical distribution of the pressure and resulting wave-induced horizontal forces/pressures, which were not measured in the physical model studies. The simulated results indicate that the pattern of pressure distributions at the frontal face of the elevated structure was controlled by water depth and wavebreaking types (nonbreaking, breaking, and broken waves). The wave induced-vertical force on the elevated structure strongly depends on wave height and the air gap, which is a net elevation from the still water level to the bottom of the structure, but the horizontal force shows complicated patterns due to the varied surge levels (flow depth), wave heights and air gaps. The new dimensionless parameter, α′/h, comprised of the air gap, incident wave height, and flow depth, is introduced and utilized to predict the horizontal forces on the elevated structure.more » « less

Abstract Given the wide utility of radial vibration of the arterial wall for clinical values, this paper presents a theoretical study on the relations of radial vibration of the arterial wall to pulsatile parameters in blood flow. Pulse wave propagation in an artery is formulated as a combination of the governing equations of blood flow and the arterial wall and no-slip conditions at the blood-wall interface and is analyzed to obtain the wave velocity and the theoretical expressions for blood flow rate and radial wall displacement in terms of pulsatile pressure. With the harmonics of a pulse signal, theoretical relations of radial vibration of the arterial wall to pulsatile parameters in blood flow are derived under two conditions: without and with wave reflection. These theoretical relations identify the assumptions for the simplified relations employed in the utility of radial vibration of the arterial wall for clinical values. With the arterial wall treated as a unit-mass vibration system, these simplified relations are utilized for extraction of arterial indices from radial vibration of the arterial wall. Other applications of such relations for clinical values are discussed, and the interaction between the arterial wall and blood flow is further revealed from the perspective of energy and one-dimensional wave equations. With harmonics and wave reflection considered, the derived theoretical expressions for radial wall vibration, pulsatile parameters in blood flow, and the relations between them provide theoretical guidance for improving their interpretation of clinical values with clearly defined physiological implications and assumptions.more » « less

Offshore foundation elements are often subjected to cycles of compressive and tensile loading. Open-ended pipe piles are frequently used as foundations for wind turbines as monopiles or as part of jacket structures. This paper reports the results of two open-ended pipe pile tests in a half-cylindrical calibration chamber with image analysis capabilities. The model piles, with diameters of 44 mm and 63 mm, were jacked into dense silica sand samples, statically load tested in compression, cyclically load tested (under displacement-controlled conditions), and statically load tested in compression a second time. The cyclic load tests had 100 cycles with a half-amplitude of 1 mm. Digital images captured during testing were analysed using digital image correlation to obtain the displacement fields in the soil domain. Image analyses of compressive static load tests indicate that the soil plug undergoes vertical compression during static loading. Cyclic loading leads to shaft resistance degradation, which is correlated with contractive radial strains around the model pile. Cycling also causes vertical compression below the pile base and inside the soil plug, which increases the base resistance of the piles and ultimately increases the total compressive capacity of the model open-ended piles under static loading.more » « less
