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...
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....
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...
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...
A New Approach to Activated Sludge Plant Design
Activated sludge plants are designed on the basis of stationary tests at laboratory scale for constant organic loads and constant input flows. From these tests the kinetic parameters are...
Land Treatment of API Separator Sludge
An extensive research project was undertaken to establish design and operational guidelines for treatment of oily sludge using land treatment systems. Forty-five test plots were established...
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...
Structural Safety Studies
Structural engineers are most concerned with the safety aspect of structures. The primary objective of structural engineers is to produce structures which are satisfactory in meeting certain...
Drilled Piers and Caissons II
Drilled piers or caissons, also called drilled shafts or bored piles, have long been a very cost effective foundation solution for many soil profile and load situations. A distinct advantage...
Annual and Seasonal Variations of Phosphorus Loads in the Okanagan River
Results of monitoring of phosphorus loads in the Okanagan River channel linking Okanagan, Skaha and Osoyoos Lakes are described. The southern Okanagan basin is the area where major changes...
Agricultural Nonpoint Source Control Program for Lake Erie
Congress mandated (PL 92-500, Sec. 108d and 108e) that the U. S. Army Corps of Engineers design and develop a program for the rehabilitation and environmental repair of Lake Erie. The...
A Carrying Capacity Study of Hatteras Island
This article summarizes a study done of Hatteras Island, North Carolina, a largely undeveloped and natural barrier island. 'Carrying capacity' means the ability...
