INTRODUCTION A research study, conducted at Cornell University, provided a theoretical method for evaluating the state of stress for both C- and Z- purlins subjected to wind uplift loading. According to the Cornell analytical method, a Z-purlin has more load carrying capability than a similar C-purlin. Although experimental verification was provided, questions were raised, within the Metal Building Industry, regarding the strength of the C-versus the Z-section. The purpose of the work discussed herein was to develop information regarding the behavior of C- and Z-sections having identical cross-section dimensions. A brief description of the test program, along with a comparison …

INTRODUCTION In recent years, insulated steel roof deck construction has been widely used in industrial and commercial buildings. The use of roof assembly consisting of 3-in. deep, 22-gage, steel deck is being considered by Rooftex, Inc. of Houston, Texas, for Class 1-60 and Class 1-90 assemblies. At the request of Rooftex, two types of tests were conducted at the University of Missouri-Rolla in July 1983. These tests, which consisted of physical tests of steel roof decks and uplift pressure tests of insulated steel roof deck construction, were conducted to obtain the"necessary data for the approval of the Factory Mutual Research …

I. INTRODUCTION In February 1981, the "Guide for Preliminary Design of Sheet Steel Automotive Structural Components" was issued by American Iron and Steel Institute (AISI) for assisting automotive structural designers to achieve weight reduction through the efficient utilization of carbon and high strength steels. 1 These design recommendations were based primarily on the 1968 Edition of the AISI "Specification for the Design of Cold-Formed Steel Structural Hembers,,2 but contained the following major differences with regard to the AISI Specification, which was written 'for the design of buildings: 1,4 a. The design expressions presented in the Guide are based on an …

INTRODUCTION Cold-formed steel sections are formed from thin steel sheets, of typical thickness 0.015-0.25 inches, by either production cold roll forming or by specialized press braking. As a result, it is possible to produce economically a variety of cross-sectional shapes, which have high strength-to-weight ratios. Some structural applications include primary and secondary load-carrying framing members, such as columns, purlins and wall studs; and shear diaphragms, such as floor and roof decks and wall panels (Yu [1973]). Their design is governed by the American Iron and Steel Institute (AISI) Specification [1980], which is unique because of its generality, e.g., no specific …

INTRODUCTION In recent years, automobile manufacturers have introduced new lines of lighter vehicles for the purpose of achieving fuel economy. To construct such vehicles, formable and weldable, high strength, sheet steels with yield points ranging up to 140 ksi have been used for parts and structural components. 1.1-1.7 Because various types of newer high strength sheet steels are now available for engineers to reduce car weight and because these steels permit the use of existing production equipment with virtually no change in techniques or production rates, the design criteria for efficient and economical use of these high strength steels in …

Masters Theses
"In recent years fuel economy has become one of the major criteria for the design of automobiles. In order to improve the efficiency of their vehicles many automotive designers are substituting high strength sheet steels for traditional materials of lower strength. This thesis discusses experimental work which was done to determine the representative mechanical properties and stress-strain relationships of a select group of high strength sheet steels with nominal yield strengths ranging from 80 to 140 ksi. The results show that high strength sheet steels are quite anisotropic with the variation in measured properties depending on the type of sheet …
