Structural Stability Research Council: Proceedings 1976, Structural Stability Research Council

CCFSS Library (1939 - present)

One of the purposes of the Council is to maintain a forum where problems related to the design and behavior of columns and other compression elements in metal structures can be presented for evaluation and discussion. The Annual Technical Session provides an opportunity to carry out this function. The 1976 Annual Technical Session was held on March 2 and 3 at the SheratonBiltmore Hotel in Atlanta, Georgia. Fifty-five persons attended the session and nineteen papers were delivered. A panel discussion on "New Ideas on Stability of Multistory Buildings" was held in the evening of March 2, 1976. the panelists were …


Report On Screw Fastened Sheet Steel Connections For Canadian Steel Industries Construction Council, Volume I, R. W. Eastman Jan 1976

Report On Screw Fastened Sheet Steel Connections For Canadian Steel Industries Construction Council, Volume I, R. W. Eastman

CCFSS Library (1939 - present)

Ultimate load data is presented from more than 1600 tests on sample connections made with different thicknesses of zinc-coated sheet steel and a variety of commonly used thread forming and self-drilling fasteners. The three fundamental loading conditions examined were pull-over, pull-out and single lap shear.

Empirical relationships have been developed which allow interpolation of the data within the range of sheet steel thicknesses tested.

Type AB and type A thread forming fasteners, and a number of different self-drilling fasteners were tested, in sizes from #14 (.250 in.) to #8 (.164 in.) diameter. Flat metal washers and a variety of sealing …

A High-Accident Spot-Improvement Program, Kenneth R. Agent, John A. Deacon, Robert C. Deen Jan 1976

A High-Accident Spot-Improvement Program, Kenneth R. Agent, John A. Deacon, Robert C. Deen

Kentucky Transportation Center Research Report

As a result of an extensive before-and-after accident study, the high-accident location, spot-improvement program in Kentucky, although not a costly program, was found to have significantly decreased the number of motor vehicle accidents. Favorable benefit-cost ratios indicated that the cost of the program has represented a good investment in comparison with the resultant savings in accident costs. The spot-improvement program had little effect on average accident severity as measured by a severity index. Detailed analysis of available accident data showed that, for studies of the type reported, the 12-month period immediately prior to the date of identification of a high-accident …


Viscoelastic Cylindrical Pressure Vessel With Variable Inner Radius, A. N. Joshi Jan 1976

Viscoelastic Cylindrical Pressure Vessel With Variable Inner Radius, A. N. Joshi

Electronic Theses and Dissertations

The objective of this thesis is to predict from a theoretical basis the stress redistribution processes occurring within the viscoelastic core of a cylindrical pressure vessel reinforced by an elastic casing around the outer perimeter, and subject to internal pressure applied to the time-dependent inner boundary of the cylinder. The problem so stated requires development of a new technique leading to a solution for a mixed boundary value problem for a viscoelastic body occupying an ablating cylindrical y-shaped region. The approach taken in this thesis consists in reduction of a governing integro-differential equation to an equivalent set of algebraic equ3tions …


Management Of The Great Salt Lake: A Research Plan And Strategy, Craig T. Jones, Calvin G. Clyde, J. Paul Riley Jan 1976

Management Of The Great Salt Lake: A Research Plan And Strategy, Craig T. Jones, Calvin G. Clyde, J. Paul Riley

Reports

The primary purposes of this report are to indicate the following two research items in connection with the management of the water resource system of the Great Salt Lake:\ 1. Research needs and priorities. 2. A research coordination strategy. Research needs are identified by the report in terms of (1) various management, or use, categories (such as lake industries), and (2) the need to understand the physical characteristics of the lake system itself. The research needs are identified in each category as information (including data) or understanding gaps, in cases where there seems to be sufficient information, a research need …


Capability Of Integer Programming Algorithms In Solving Water Resource Planning Problems, Trevor C. Hughes, William J. Grenney, A. Bruce Bishop, Calvin G. Clyde, Rangesan Narayanan, Paul E. Pugner Jan 1976

Capability Of Integer Programming Algorithms In Solving Water Resource Planning Problems, Trevor C. Hughes, William J. Grenney, A. Bruce Bishop, Calvin G. Clyde, Rangesan Narayanan, Paul E. Pugner

Reports

The feasibility of optimizing large regional water resource planning problems by means of integer programming algorithms is analyzed. Two types of integer programming models are developed: (1) A water supply model including 23 separate but geographically related community systems; and (2) a river basin water quality model including 15 point sources of wastewater, 4 types of pollutants, 6 surveillance points, and 7 alternative treatment processes. The water supply model was structured as a mixed integer problem (some continuous variables included) while the water quality model was an all integer problem. Four integer programming algorithms were tested on the sample problems …

A Computer Graphics Analysis Of A Freeway Merge Control System, Thomas Alan Risher Jan 1976

A Computer Graphics Analysis Of A Freeway Merge Control System, Thomas Alan Risher

Retrospective Theses and Dissertations

In 1975, C.S. Bauer completed a doctoral dissertation at the University of Florida which treated the Green Band Merging Control System on I-75 in Tampa, Florida. In this work, Bauer suggested the possibility for the use of computer graphics as a toll for analysis of the bands generated by the Green Band Control System Simulation developed in his dissertation. The use of computer generated movies of the bands displayed to ramp drivers by the system allows the comparison of various band control strategies without the need for field implementation and testing. With the goal of producing such films in mind, …

Sewer System Design For Camp Challenge And Determination Of Per Capita Wastewater Flows From Vacation Facilities, William C. Goucher Jan 1976

Sewer System Design For Camp Challenge And Determination Of Per Capita Wastewater Flows From Vacation Facilities, William C. Goucher

Retrospective Theses and Dissertations

A sewer system was designed for Camp Challenge of the Florida Easter Seal Society, in Mount Plymouth, Florida, of polyvinyl chloride piping. Invert elevations were tabulized and necessary fittings determined for the system. Cost estimates were also included. The sewers were designed on a per fixture basis so as not to overdesign using per capita flow rates. A literature and records search was conducted to obtain design and actual wastewater flow quantities in gallons per capita per day (gpcd). Actual flows determined from 4 camps and 11 travel trailer parks gave average values of 39 and 33 gpcd, respectively, and …
