Structural modelling of plasterboard-clad, light timber framed walls in fire
… to be lacking in the literature. A series of full-scale experiments were conducted on timber framed assemblies under ambient and elevated temperature conditions. The variability, end restraint conditions and contribution of the sheeting were carefully controlled and examined in the …

Övertändning, backdraft och brandgasexplosion sett ur räddningstjänstens perspektiv
… Sweden. The description is based on a number of full- scale experiments which were carried out within the project. At the end of the report, possible warning signs of a potential flashover and backdraft are discussed. In the appendices, a number of models used to predict flashover are evaluated, …

Behaviour of long span composite beams with precast hollow-core slabs
… concrete slabs. To achieve this, five full scale bending tests were carried out supplemented by horizontal push tests. In addition to the experimental work described, an analytical study is conducted and design recommendations are made. The main issues were the compression behaviour of …

Laboratory evaluation of conditioning requirements for sludge dewatering using belt filter press
… of this study were to develop a reliable bench-scale testing procedure to adequately predict polymer conditioning requirements for full-scale belt filter presses, and to determine the additional polymer demand exerted by applied pressure during the expression stage of a dewatering process. …

Characterization, modeling and mitigation of vortex-induced vibration of slender cylinders
… an analytical/numerical components. A series of full-scale experiments was conducted to monitor wind-induced vibrations of a number of representative types of mast arms of traffic signal support structures and, on this basis, to characterize the vibrations and reveal the underlying excitation …

Sacrificial bearing components for quasi-isolated response of bridges subject to high-magnitude, low-probability seismic hazard
… with stiffened, L-shaped retainer brackets. Full-size bearing specimens were subjected to compression loads of up to 100 kips, cyclic displacements of up to 12-1/2 inches, and velocities ranging from quasi-static up to 4 inches per second. Bearings were tested – to simulate both longitudinal …

Modeling buoyancy-driven airflow in ventilation shafts
… (CFD) models that haven been validated by small scale and full scale experiments. The full scale experiment provides a detailed data set of an actual atrium that can be used in further validations and demonstrates the first use of a neutrally buoyant bubble generator for flow visualization and …

NON-DIMENSIONAL DATA-DRIVEN MODELS OF COMPUTATIONAL FLUID DYNAMICS (CFD) OF MULTI-PHASE FLOW IN ANNULUS
… simulations can be employed. However, the full-scale experiments are very costly, and the coupled full-scale simulations are time-consuming. To overcome these challenges, a scalable model is required to connect the cavitation criterion, pressure conditions, and geometric parameters of the …

Turbulence Modeling and Simulation of Unsteady Transitional Boundary Layers and Wakes with Application to Wind Turbine Aerodynamics
… farm location selection and wind turbine design. Full-scale experiments and high-fidelity simulations are restrictive due to the prohibitively high cost, while the model-scale experiments and low-fidelity calculations miss key flow physics of unsteady high Reynolds number flows. A hybrid RANS/LES …

Nonlinear behaviour of precast concrete frames
… simple questions or by returning default values. Full scale experiments were carried out on eight column beam subframes to validate the computer program. Each subframe consisted of a two storey column with a short length of a typical mid-storey beam. Four types of connection commonly used in …

Simulation of the In-plane and Out-of-plane Seismic Performance of Nonstructural Partition Walls
… various configurations.Initially, a series of full-scale experiments is performed at the UNR-NEES site to investigate the system-level response and damage mechanisms of nonstructural systems, including cold-formed steel-framed (CSF) gypsum partition walls. The experiments reveal that the …

Evaluation of Steel H-Piles with Localized Corrosion and Rehabilitation Using Friction-Type Bolted Steel Plates
The work presented in this dissertation has two major research objectives related to steel bridge piles with severe but localized corrosion: (1) development of a numerical framework to predict the axial capacity of the corroded piles, and (2) development and evaluation of a friction-type bolted …
