Structures Congress 2007
The Congress' technical program was designed with the practicing structural engineer in mind while maintaining a rigorous standard for the academic presentations. Topics include:...

Detailing and Design Examples for Torsional Members
The nature of the internal force flow in a concrete member subject to torsion brings about both longitudinal and transverse force components. The resulting tension brought about by the...

Application of Water Column Dampers to Control Motions of the Wall Centre, Vancouver
The Wall Centre, a 450 foot tall high-rise tower currently under construction in downtown Vancouver will be the highest building to be constructed in that city. Wind tunnel testing indicated...

Control of Wind Response of the Trump World Tower
The Trump World Tower is a luxury residential building located on 1st Ave. and 48th St. in New York City,...

How Spacing of Cross-Section Surveys Affects Understanding of Variability in Channel Hydraulic Geometry

Channel Stability Assessment for Flood Control Projects
This manual provides assistance for determining potential channel instability and sedimentation effects in flood control projects. It is intended to facilitate consideration of the type...

Application of High-Resolution Schemes to Free Surface Flows in Irregular Channels
A 1-D flow model employing a high resolution scheme based on the Total Variation Diminishing concept is applied to non-prismatic channels of irregular cross-section. The hydraulic properties...

Optimal Geometric Shape of a Surface Aeration Tank
This paper presents the results of a laboratory investigation on three cross-sectional shapes—square, rectangular and circular of surface aeration tanks, without any baffles, to find out...

Simulation of Regional Ground-Water Flow on a Transboundary Flowline; Trans-Pecos, Texas and Chihuahua, Mexico
A two-dimensional, steady-state, cross-sectional model was used to evaluate boundary conditions, residence times, and potential transboundary movement along a 28 mi (45 km) flowline between...

Optimal Sizing of Width- and Depth-Constrained Trapezoidal Channels
Open-channels are often designed based on the assumption of uniform flow and normal depth. If a channel is to be lined with a nonerodible material, the dimensions of the channel can be...

Reliability of High-Strength Concrete Columns

Vibration Analysis of Special Orthotropic Plate with Variable Cross-Section, and with a Pair of Opposite Edges Simple Supported and the Other Pair of Opposite Edges Free

High-rise Telecommunication Tower with a Square Cross-section, Peculiarities Concerning Wind Forces and Construction

Preliminary Sensitivity Studies of Fast-Path Flow on a Cross-Section of Yucca Mountain, Nevada

Second-Order and Overall Stability Analyses for Tall Building Structures with Stepped Cross-Sections and with Floor Slab Deformations Considered

Improving Dynamic Finite Element Models Using Test Data
A structural optimization based method was developed to improve the finite element model to achieve good agreement with the test results. The modal displacements at critical locations...

Seismic Design of RC Structural Walls with Unsymmetrical Cross-Sections
An overview of seismic design issues and current experimental research for walls with unsymmetrical cross-sections is presented. The experimental studies include approximately 1/4 and...

Optimization of Controlled Structures: Using H Theory
This paper presents the algorithm for the design of a controlled structure in which the structural and control systems are designed simultaneously. The problem is posed as an optimization...

A Comparative Analysis of Estuarine Circulation Simulation Using Laterally Averaged and Vertically Averaged Hydrodynamic Models
Multidimensional models are routinely used to characterize hydrodynamic and transport processes in estuarine and coastal ocean systems. Due to a variety of factors, the choice between...

Wetland Loss Rates and Agricultural Drainage
The current paper uses National Resources Inventory data to document the relation between private on-farm agricultural drainage investment activity and wetlands loss. The paper presents...
