Physical Model Tests of Dolos Impact Stresses
An on-going experimental study to determine impact stresses and static nesting stresses in instrumented large scale model dolosse is described in this paper. Seven dolosse were instrumented...

Modelling of Extended Endplate Bolted Connections
A methodology based on finite element modelling is examined to study the behaviour of extended endplate bolted connections. ANSYS (Rev. 4.4), a large scale finite element program is used...

Multi-mode Aerodynamic Analysis of Long-Span Bridges
Multi-mode responses to wind excitation have been estimated in the past by considering the response of each mode and then taking the root-sum-square for the total response. Other procedures,...

Estimation of Structural Damping of Buildings
The full-scale data on damping ratio are collected from 77 buildings within Japan. Almost all data are obtained from vibrations with a very small amplitude such as microtremor, man-power...

Spherical Domes Subjected to Horizontal Earthquakes
The purpose of this paper is to get a powerful tool for response analysis of a spherical dome subjected to dynamic excitation based on mathematical analytic method, i.e., the Galerkin...

Comparison of Two different Models of a Shell Roof
The main purpose of this study is to compare a physical model of a shell roof with a theoretical model of the same shell roof in order to verify the reliability of the Homeostatic Model...

Modeling of Deep Water Outfall Plumes in the East Australian Coastal Ocean
The paper reports on the modeling study of deep water outfall plumes in the east Australian coastal ocean. The primary aims of the modeling were to provide estimates of plume condition...

Numerical Modeling of Advective and Diffusive Transport in the Rappahannock Estuary, Virginia
A laterally integrated, two-dimensional real-time model, consisting of linked hydrodynamic and water quality models, was developed to study hypoxia in the tidal Rappahannock River, a western...

Tributary Loading with a Terrain Following Coordinate System
The modeling of physical processes that occur in a tributary between the farthest downstream gage and the lake interface can help to improve the predictive capabilities of Great Lakes...

Analysis of Prototype Long Period Waves for Los Angeles/Long Beach Harbor Resonance Studies
Long period wave data have been collected at an offshore wave gage and system harbor gages for over eight years in the Los Angeles/Long Beach Harbor region. These expansion of the harbors....

Physical Modelling of Multidirectional Waves
A sixty-segment wave generator has been used since 1985 at the Coastal Engineering Laboratory of the National Research Council (NRC) of Canada to generate multidirectional waves, and study...

Wave Transformation and Load Reduction Using a Small Tandem Reef Breakwater – Physical Model Tests
The performance of several small reef breakwaters, and a tandem breakwater system (consisting of a reef breakwater positioned upwave from a surface-piercing main breakwater), are quantified...

A Decision Support System for Multi-Purpose Reservoir Operations
A generalized decision support system (DSS) is presented for developing optimal operation policies for multi-purpose reservoirs. The model is designed for single reservoirs, although is...

A Physically Based Conceptual Model for Simulating Contaminant Levels in Subsurface Water
A conceptual physical model is developed to simulate solute transport and mixing in the vadose (unsaturated) and groundwater zones. The conceptual model couples lumped-parameters models...

Optimal Operation of Soil Aquifer Treatment System
Mathematical models based on nonlinear programming are developed for operating soil aquifer treatment(SAT) systems. The objective of these optimization models is to determine the operation...
