Deepwater Waves and Tsunami Produced by the Impacts of Small Asteroids
Studies of ocean sediments may be used to determine when coastal areas have been hit by tsunamis in the past. Tsunami debris has been found to be associated with the Cretaceous-Tertiary...
The Use of Coda Waves for Characterizing the Site Effect on Strong Ground Motion
The well established separability of source, path and site effects on coda waves of local seismic events offers the most effective means for determining the site amplification factor empirically....
Seismic Behavior of Type PR Steel Frames
Type PR(partially restrained 'simple framing') is one of the methods of design specified in the AISC LRFD(1986) Design code for the design of unbraced steel building frames. In this method...
Practical Application of Tuned Liquid Damper for Tall Buildings
Performance of TLD, based on the full-scale measurement of an actual tall building, is discussed in this paper. Wind induced vibration of the SYP Tower was measured during a gusty day,...
Some Aspects of Determination of Pile Capacity by the Wave Equation
This paper presents some new observations made during correlation study of pile capacity computed by wave equation analysis with failure load from static test. In order to determine proper...
Laser Generation and Detection of Ultrasound in Concrete
Laser ultrasonics is a non-contact nondestructive evaluation method that uses lasers to generate and detect elastic waves. In this work, laser ultrasonics is used to produce broadband...
Impact of Non-Gaussian pdf on Reliability Estimates for Deep Water Platforms
The offshore community has invested a great deal in the analysis and design of compliant deep water platforms such as tension leg platforms (TLPs) and more recently spar platforms. Tension...
Effects of Sea Surface Movement on Offshore Structures
Examinations are made of the effects of the sea surface movement on the fundamental model response of deep-water, Wave-excited offshore structures. These effects are accounted for by using...
Seismic Behavior of Non-Ductile Concrete Frame Structures
Non-ductile reinforced concrete (RC) frame structures designed and constructed during the 1950's through 1970's exist in many regions of the United States. The frames of these structures...
Review of Cold-Formed Steel Purlin Design
The use of cold-formed steel members as roof purlins for single story industrial and commercial buildings is commonly recognized. These members typically have either a C- or Z-shaped cross...
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,...
Buckling of Single Layer Latticed Dome under Uniform Gravity Load
This paper reports on experiment and numerical analysis relating the buckling of a single layer latticed dome under uniformly distributed nodal gravity load at the dome central portion....
Performance and Analysis of Frames With URM Infills
The interaction of unreinforced hollow concrete block masonry (URM) infill walls and gravity load designed (GLD) frames has been studied at Cornell University. The primary goal of this...
Nonlinear Earthquake Analysis of Concrete Gravity Dams Including Sliding
The sliding stability of a concrete gravity dam during a design earthquake must be investigated to assess the seismic safety of the dam. A new numerical procedure for solving the equations...
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....
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...
