Damage Model for Buildings Subjected to Earthquakes
A model based on random vibration method is developed for assessing building damage to earthquakes. The damage of reinforced concrete structures is expressed as a linear combination of...

Loads Due to Human Movements
The live loads due to human actions are random functions being modeled from data obtained from tests to determine load histories for the actions of individuals and small groups of people...

Bridge Inspection by Dynamic Loading Technique
This paper describes, a case study of the evaluation of the structural integrity of a New York State Thruway bridge using the dynamic loading technique. The study was undertaken in a effort...

Computer-Aided Studies of Complex Soil Moduli
Low-cost microcomputers and new electronic components make it possible to measure accurately the phase and amplitude of mechanical waves in the frequency domain at a small fraction of...

Seismic Analysis of Horse Creek Dam, Hudson, Colorado
On April 8, 1981, six days after a Richter magnitude 4. 0 earthquake, inspectors from the Colorado State Engineer's Office discovered a small crack in outboard side of Horse...

Dynamic-Fatigue Response of Continuous Composite Bridges
The dynamic response of continuous composite bridges and the influence of fatigue loading at resonance frequency on the structural response are investigated. It is shown that cracking...

Strength of Biaxially Loaded SRC Columns
The paper presents the results of an experimental study on the elasto-plastic behavior of 'Steel reinforced concrete (SRC)' columns subjected to biaxially eccentric...

Composite and Mixed Construction in Czechoslovakia
Various composite and mixed systems have been used in Czechoslovakia. Special attention is focused on design methods, effective construction, and material savings. Current developments...

Storage Projection for Reservoir Systems
Two methods are studied for determining the probability distribution of future levels of storage in a reservoir system: transient analysis and Gould's probability matrix method....

Time Series Analysis of Hourly Domestic Water Demand
Design flows for water supply and sanitary sewer systems are chosen by rules of thumb in the absence of actual data. This research develops two stochastic models of water demand by analyzing...

User-Friendly Reservoir Routing on Minicomputers
Two models for routing reservoir releases and computing reservoir elevations for the TVA reservoir system are described. The models are designed for use on a 16-bit minicomputer with a...

Impact of Dynamic Loading on Bio-Phosphorus Removal
The ability of bench-scale activated sludge biological phosphorus removal systems to produce effluents with consistently low phosphorus concentrations was influenced by influent TOC/COD...

Optimization Issues in the Design and Control of Large Space Structures
The optimization and identification issues which arise in the design and control of large flexible space structures are reviewed. The first paper examines the use of several different...

Coastal Erosion Management in Australia and the U.S.
Current knowledge and management policies in both Australia and the U. S. favor non-structural over structural responses to coastal erosion problems wherever possible. The trend towards...

Examples of Sediment Distribution in the Italian Adriatic Coast. A Comparison Between the Shepard and the Nota Textural Classifications
Four sectors of the western Adriatic coast, each with a different feature, represent the test areas to evidence the differences between the two textural classifications of sediments by...

Hurricane Evacuation Studies, an Overview of Major Analyses
The purpose of this manuscript is to present the methods employed, the types of data generated and the interrelationships of the major analyses conducted for a hurricane evacuation study....

Construction-Induced Dynamic Pressure and Corresponding Impact Factors for Pipelines
The Bureau of Reclamation, U. S. Department of the Interior, conducted a study which measured pressure exerted by construction scrapers on a rigid, buried, instrumented concrete slab....

Experimental and Field Observation of Dynamic Behavior of Buried Pipelines
Cyclic torsion, axial pull-out, and bending data from experiments conducted on jointed utility pipelines buried at several depths are presented. It is found that linear relationships exist...

Dynamic Responses of Buried Pipelines
The dynamic responses of the pipelines are analyzed by the continuous mass matrix method by considering the soil as a bounded plane in which the pipeline is placed. The friction between...

An Operational Dynamic Routing Model for Small Computers
The paper reports on a study to develop an efficient dynamic routing procedure that can be used on an IBM PC/XT microcomputer as the routing component in a comprehensive watershed simulation...
