Node Factor Variations and Joint Occurences
In constructing exceedance frequency distributions for extremal heights resulting from joint occurrences of tsunamis or storm surges and the astronomical tide, a period of time for the analysis must be...

Seismic Behavior of Moment Connections and Joints
The behavior of moment connections and beam-column joints in moment resisting steel frames subjected to severe earthquakes is studied. The cyclic inelastic deformation capacities of different types of...

Evaluation of Selected Initial Dilution Models
A number of mathematical and computer models are currently available to calculate initial dilution of treated wastewater effluent discharges into the ocean. This paper presents a comparative evaluation...

Columns with Semirigid Joints
The influence of realistic semi-rigid end restraint on the strength and behaviour of real steel columns is investigated. An analytical procedure is developed which includes the effects of initial out-of-straightness,...

Photosynthesis-Light Mathematical Formulations
Photosynthesis-light curves for photoplankton describe the characteristic dependence of the instantaneous rate of photosynthesis on incident light. Six different mathematical formulations are evaluated...

Transverse Forces on Vertical Tube Array in Waves
In a wave tank test with a vertical array of tubes the inline and transverse forces on small instrumented sections of the tubes were measured. The transverse forces on them and the total force profiles...

Computer Design of Landfill Methane Migration Control
Computer programs for the design of methane migration control systems around sanitary landfills are described. These programs allow the effectiveness of individual designs to be evaluated and allow comparison...

Modified Analysis of Reinforced Concrete Beams
A method for analyzing reinforced concrete beams and beam-columns is developed, and the analytical results are compared to experimental data obtained by other investigators. The present method employs...

Resistance of Beauharnois Canal in Winter
The flow in an ice-affected river can be calculated using the open-water Chezy equation and ignoring the presence of ice if a corrective coefficient for Chezy's C is introduced to take into account the...

Simulation of Large-Scale Circulation in Harbors
A numerical model capable of simulating vertically-integrated tidal circulations in a harbor area for a substantial long period of time has been applied to the Los Angeles-Long Beach Harbor. The computed...

Heat Loss from Rapid Infiltration Basin in Winter
A method to estimate heat losses from a rapid wastewater infiltration basin under winter operation is developed. The analysis is theoretical and considers two modes of operation, one with a permanent ice...

Beam-to-Column Connection Research in Japan
Present status of the research on the beam-to-column connection in Japan is reviewed. The design philosophy of beam-to-column moment connections of steel building frames under the unique situation that...

Investigation of Failures
The problems associated with determining what actually happended after an unexpected instability has occurred are illustrated by case records. Examples are taken from failures of cut slopes in, and embankments...

Scattering of SH Waves by Subsurface Topography
Horizontally polarized shear waves in an elastic alluvial valley of arbitrary shape perfectly bonded to a linearly elastic, homogeneous and isotropic half space are considered. The valley is subjected...

Torsional Dynamic Response of Solid Media
A new, practical method is proposed for solving the partial differential equations describing the dynamic behavior of either linear elastic or nonlinear inelastic multi-dimensional continua. The ultimate...

Stochastic Model of Incipient Sediment Motion
A stochastic model of incipient sediment motion is developed. The probability of incipient motion, the life distribution of stationary particles, the number distribution of particles in incipient motion,...

Beams, Frames and Shells on Elastic Foundations
Explicit stiffness matrix, present matrix and nodal forces are used as a basis for computer analysis of beams, rings, simple frames, and branched shells of revolution on a three-parameter foundation model....

Hot-Film Response and Digital Analysis in Bubly Flows
Hot film responses in bubbly flows are analyzed for the development of a digital analysis technique. It is shown that hot-film anenometry and digital data analysis techniques can be excellent tools for...

Three-Dimensional Slot Jets
A comparison between a momentum flux analysis and data for slot jet of limited aspect ratio is described for one set of consistent data. It is shown that an analytic model, based on the synthesis of momentum...

Mapping Landslide Hazards in Forest Watersheds
A physically realistic methodology is presented for estimating and mapping landslide hazards for watersheds. This methodology also considers the variability of the controlling factors. A demonstration...
