Probabilistic Models For Construction Estimating And Bidding, James E. Spooner
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 …
Computer Assisted Teaching Of Steel Design, Wendelin Henry Mueller Iii
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 …
The Structural Behavior Of Cold-Formed Steel Members With Perforated Elements, Charles S. Davis
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 …
