The Eurocodes and Shrinkage in Composite Beams
The two parts of this paper relate to different aspects of design procedures for composite structures of steel and concrete. First, recent developments in the coordination of the eight...
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...
Beam-to-Column Connection of a Composite Structure
Composite structures can exhibit excellent performance against seismic force, and fire safety as well. However, the traditional steel reinforced concrete (SRC) system or concrete encased...
Beam to Column Stress Transfer in Composite Structures
To clarify the mechanism of the stress transfer from the steel beam to the composite column through the beam-column joint, eight exterior beam column assemblies were tested under reversed...
Seismic Strengthening of Existing RC Buildings
Seismic strengthening of existing reinforced concrete (RC) frame buildings by the use of steel braces or panels was studied experimentally. A special joint between steel elements and the...
Timber Bridge Decks
The portion of the nation's 500,000 bridge decks that are made of timber has been declining for years, as the old timber ones on secondary road bridges are rebuilt, in most...
Critical Load Program
The elastic critical load of a structural frame is a fundamental parameter in assessing its stability. It is an upper bound to the failure load of the frame, in the same way that the Euler...
Computers in a Planning Context: Another Reality
Over the past twenty years water resources planning has seen a great increase in the development of computer methods of analysis. This has transformed the way the hydrology, hydraulics,...
Quantifying Social and Environmental Objectives
Over the past decade, there have been great improvements in economic and multiobjective techniques for quantifying social and environmental objectives in water resources planning. Nevertheless,...
Water Develoment Models for Contemporary Planning
A methodology for evaluating water planning alternatives was developed and applied to the Nebraska Platte River. The methodology involved a micro-computer based screening model and a multi-objective...
An Economic and Financial Planning Model
A comprehensive computer model for generation planning has been developed and applied to several large-scale power sector master plans. A unique feature of this model is the concurrent...
Analysis of Reservoir Operations on the IBM-PC
The optimization of reservoir operations is a major economic concern. This paper contributes a computer software package, SPORO, written for the IBM-PC, for the stochastic optimization...
Practical Water Demand Forecasting
The authors describe their experience in designing, building, and applying a water demand forecasting model for the Denver metropolitan area. In the presence of incomplete and sometimes...
Micro-Computer Water Develoment Screening Models
A micro-computer screening model was developed to analyze the physical and economic efficiencies of a large number of alternative options associated with a given water development project....
Personnel Policies for Operations Management in the Computer Age
The human factor is an essential ingredient and the key element in successful computer applications for water resources or any other field. Engineers in general, and engineering managers...
Application of Phosphorus Models to New Mexico Reservoirs
Many empirical, mass-balance phosphorus models have been developed and tested on northern, temperature lakes and previously published. Fourteen of those published models were tested on...
Microcomputer Application in Predicting Upland Erosion
An erosion-deposition model, originally developed for a mainframe computer, was adapted for an Apple IIe. With minimal adjustment it can also be used on other personal microcomputers....
Enhanced Mobility of Polynuclear Aromatic Compounds in Soil Systems
The objective of this study was to determine adsorption isotherms for polynuclear aromatic (PNA) compounds in methanol and a mixture of 50 percent methanol 50 percent water. The adsorption...
A Modified RBC Design: Performance Evaluation
An RBC (rotating biological contactor) system was designed using Pall rings type 40, and tested under high organic surface conditions. Influent soluble BOD averaged at 55 mg/l, equivalent...
Resource Recovery Mass-Burning Incineration
The various types of incineration systems are discussed, and the technical and economic factors to be considered in developing a resource recovery project are examined....
