Structural Test And Analysis Of A Vierendeel Steel And Concrete Composite Girder, Melvin Crews Oestreich Jan 1972

Structural Test And Analysis Of A Vierendeel Steel And Concrete Composite Girder, Melvin Crews Oestreich

Masters Theses

"The results of the structural load testing of a unique type of steel and concrete composite girder are described. The structural system, referred to as a composite Vierendeel girder, is a hybrid type which incorporates features of a castellated beam and a Vierendeel truss. The performance of the composite girder agreed reasonably well with calculated values based on section properties for a prismatic beam. Observations indicated web stiffeners were required on the stub beams to prevent premature failure of the system. Failure of the girder was due to concrete crushing over a stub web beam. Design considerations for a structural …


Characterization And Staged Lagoon Treatment Of Swine Feedlot Waste, Abraham H. Loudermilk Jr. Jan 1972

Characterization And Staged Lagoon Treatment Of Swine Feedlot Waste, Abraham H. Loudermilk Jr.

Masters Theses

"Feedlot pollution is developing into a serious problem because of the trend toward intensive farming techniques and the increasing number of animals in confinement feeding operations. The purpose of this study was to characterize swine waste collected under a slotted feeding floor using a water-carriage system, and to evaluate the treatment of this waste in a staged lagoon system consisting of an anaerobic, a dual anaerobic-aerobic, and an aerobic lagoon. A small feeding floor unit capable of maintaining 3 separate groups of animals, and a pilot 3-lagoon system were designed, constructed, and operated for a period of approximately 4 months. …


Probabilistic Models For Construction Estimating And Bidding, James E. Spooner Jan 1972

Probabilistic Models For Construction Estimating And Bidding, James E. Spooner

Doctoral Dissertations

"Two probabilistic models are offered as a means for quantitatively determining contingency in a lump-sum bid. The first model is based on the isolated project and requires subjective evaluation of probabilities associated with the individual elements of the estimate. Contingency is defined as a function of the standard deviation of project field costs. Procedures are developed to obtain the variance of the total field cost from three-value estimates of the primary quantities. The second model considers the business as a stochastic process with an initial risk reserve and a positive risk loading, and contingency in this model is a function …


The Structural Behavior Of Cold-Formed Steel Members With Perforated Elements, Charles S. Davis Jan 1972

The Structural Behavior Of Cold-Formed Steel Members With Perforated Elements, Charles S. Davis

Doctoral Dissertations

"Analytical and experimental investigations have been conducted to study the influence of perforations on the structural behavior of cold-formed steel structural members. Since in many cases, the load-carrying capacity of cold-formed steel members depends on the buckling behavior of individual component elements, emphasis has been concentrated on the study of the instability and post-buckling strength of perforated elements. In this investigation, the buckling loads and post-buckling strength of stiffened and unstiffened compression elements having single circular and square holes have been studied analytically by using the finite element method. The effects of different holes on the buckling coefficient have been …


Computer Assisted Teaching Of Steel Design, Wendelin Henry Mueller Iii Jan 1972

Computer Assisted Teaching Of Steel Design, Wendelin Henry Mueller Iii

Doctoral Dissertations

"A method for use in creating a university level course is presented. The specifics of each of the steps is given in general terms to allow its application to as many different topics as possible. This method is then specifically applied in the formation of a fundamental steel design course using the American Institute of Steel Construction Specification. The reasoning utilized in each phase of development is documented. A lecture style presentation complemented by a series of student oriented computer programs was chosen for use. The details of the course material in outline form is given along with the computer …


High Speed Magnetically Supported Vehicles For Reducing Transportation's Degradations Of The Environment, Pravinchandra Shukla Jan 1972

High Speed Magnetically Supported Vehicles For Reducing Transportation's Degradations Of The Environment, Pravinchandra Shukla

Masters Theses

"The development of new techniques for higher speed transportation is desirable to satisfy the environmental, conservation, and economic requirements of society. Some of the important factors are presented for developing magnetically supported vehicles. A new method for improving the ratio of lift force to drag force is suggested and discussed. An application of the new technique to vehicles that would ride on a carpet of magnetism and would operate with less waste of energy is suggested "--Abstract, page ii.


Laboratory Studies Using Diffused Oxygen And Air For Hypolimnion Reaeration, Chin-Ming Pai Jan 1972

Laboratory Studies Using Diffused Oxygen And Air For Hypolimnion Reaeration, Chin-Ming Pai

Masters Theses

"The purposes of this research were to study the oxygen transfer rates and the oxygen transfer efficiencies of different types of aerators using different sources of oxygen in different types of water bodies, and to evaluate the number of diffusers required to be installed in a selected lake for hypolimnion aeration.

The experiments were conducted using a specially designed column. Four types of aerators, including a cylindrical stone diffuser, a spherical stone diffuser, and 2 ceramic diffusers (types A and B) which differed in pore size, were utilized as the aerators. The water bodies selected for the studies were Rolla …
