Load And Resistance Factor Design Of Cold-Formed Steel : Tentative Recommendation - Load And Resistance Factor Design Criteria For Cold-Formed Steel Structural Members And Commentary Thereon, Wei-Wen Yu, Theodore V. Galambos
CCFSS Library (1939 - present)
This progress report contains the following two parts: Part I: Tentative Recommendations - Load and Resistance Factor Design Criteria for Cold-Formed Steel Structural Members (pp. i-47). Part II: Commentary on Tentative Recommendations - Load and Resistance Factor Design Criteria for Cold-Formed Steel Structural Members (pp. 48-86). The tentative design recommendations are based on the statistical data presented in previous progress reports and the newly revised load factors used in Section 8.3.4 of the design criteria. The selections of ¢ factors are discussed in the Commentary for various types of structural members and connections. This investigation was sponsored by American Iron …

INTRODUCTION The flexural buckling of columns is a fundamental problem whose solution was found by Euler more than 200 years ago. Since then, refinements have extended the solution to the inelastic range and clarified the influence of initial deflections and residual stresses. Most of these advances were made by studying hot-rolled steel columns, which are widely used. Cold-formed sections are coming into greater and greater use, thanks to the great variety of geometries available, which make them suitable for specific needs, and the significant advances made in the last four decades in understanding the behavior of cold-formed steel and in …

Ultimate Strength Of Cold-Formed Steel Z-Purlins, M. A. A. Razak, Teoman Peköz
CCFSS Library (1939 - present)
INTRODUCTION Cold-formed steel structures are being widely used in various forms of construction such as industrial plants, gymnasiums, hangars and metal buildings. One important feature of metal building construction is the use of light gage roof panels connected to purlins, particularly of the Z-section. This section is, besides the channel-section, the simplest two-flange section which can be produced by cold-forming. The purlins have span lengths of 20 to 25 feet, generally made continuous over the building rigid frames by nesting. Construction details vary from manufacturer to manufacturer. The purlins available would typically have prepunched holes for connection of various types …

One of the purposes of the Council is to maintain a forum where structural stability aspects of the behavior of frames, columns and other compression-type elements in metal and compression structures can be presented for evaluation and discussion. The Annual Technical Session provides an opportunity to carry out this function. Summaries of the technical papers, the panel discussion and minutes of the business meeting are recorded in the following pages. The attendance list is also included.

Abutment-Thermal Interaction Of A Composite Bridge, David B. Lewis
CCFSS Library (1939 - present)
A two-span test structure, with tie-rods to similate approach-slab forces, was subjected to thermal loading. The resultant strains and deflections are correlated with those obtained from a prior theoretical study. It was concluded ~hat the theoretical procedure provides a rational method for predicting the thermal behavior of composite-girder bridge structures.
