Seismic Behaviour of Tall Guyed Telecommunication Towers
This paper presents results of a detailed numerical modelling study of two guyed telecommunication towers subjected to seismic excitation: a 107-m (350 ft) tower with six stay levels,...
Fabric Roof Design Responds to New Technologies
A combination of newer synthetic materials and advanced structural design technologies have given contemporary tensioned fabric roofs vastly improved energy performance and far greater...
Nonlinear Behavior of Northlight Reinforced Concrete Shells
The behavior of northlight shells is very sensitive to the boundary conditions at the top and bottom edges of the shell. The aim of this paper is to investigate the structural action of...
Efficient Nonlinear Analysis of Column-Supported Cylinderical Shells
This paper presents a finite element methodology for the study of geometrically nonlinear behavior of column-supported cylinder. Due to the discrete nature of the column supports, the...
Elasto-Plastic Buckling Design for Shallow Cylindrical Shells under External Pressure
Pressures providing elastic-plastic buckling conditions for thin shallow cylindrical shell panels are presented. Classical simple support boundary conditions have been adopted for the...
The Body Language of Tensile Structures
Considered to be a 'body' and its visual appearance as 'non verbal, intuitable information,' a building has a Body Language that is employed as a primary mode. Presented is an intuitive...
Damage Tolerance Analysis in Structural Rehabilitation
The rehabilitation of existing structures requires an evaluation by the structural engineer of past performance to determine the extent of existing damage. Following evaluation of the...
A Numerical Study of Hydraulic Jump and Mixing in a Stratified Channel With a Sill
An x-z plane two dimensional primitive equation model is used to study sill effects in a narrow channel. The aim is to examine the generation of internal bores/waves, hydraulic jumps and...
Boundary Forcing and a Dual-Mode Calculation Scheme for Coastal Tidal Models Using Step-Wise Bathymetry
Tidal energetics are persistent and important factors in almost all coastal regions. As such, it is important to employ techniques that can consistently reproduce observed tidal variations....
Issues Related to Modeling the Transport of Suspended Sediments in Northern San Francisco Bay, California
Measurements of suspended sediment concentrations at several deep-channel stations in San Francisco Bay are reviewed. Sediment concentrations are found to be strongly correlated with delta...
An Energy Based Model for Coastal Bays and Lakes
The North American Great Lakes have numerous tributary bays and small lakes along their coastline that open directly to the Great Lakes through natural or engineered channels. As a consequence...
On the Generation of Infragravity Waves by Shoaling Multidirectional Waves
The generation of long period waves in shallow water by shoaling multidirectional waves is investigate using both numerical simulations and laboratory experiments. The numerical model...
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....
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...
The Daytona Beach Large Wave Event of 3 July 1992
The fundamental mechanisms behind the anomalous large wave which struck Daytona Beach on 3 July 1992 are addressed. Although the wave was originally believed to have resulted from a submarine...
Nonlinearity in Wave Crest Statistics
The statistical properties of nonlinear wave crest amplitudes are discussed for a narrow-band random sea consistent with Stokes second-order wave theory. In particular, the probability...
Directional Wave Data ? Measurements and Modeling Coast of Florida Erosion and Storm Effects Study
The U.S. Army of Corps of Engineers, Jacksonville District, and the Florida Department of Enviromental Protection are co-sponsors of a study to evaluate the coastal processes along the...
Measured Total Wave Climate of a Small Craft Harbor
Measurements of waves in a small craft harbor were analyzed for the purpose of determining the existing wave climate energy levels causing the excessive agitation of moored small craft...
New Technology in Coastal Wave Monitoring
The Coastal Data Informational Program (CDIP) is an extensive network for monitoring waves along the Pacific coastlines of the US. The system has evolved substantially since its inception...
New Program for the Marine Observation and Prediction Center of the Central Weather Bureau
With the increase of economic activities on the oceans and seas, the observation of marine phenomena and forecast services become more and more significant. The Central Weather Bureau...
