Continuous Purlin Tests, Teoman Peköz Jan 1975

Continuous Purlin Tests, Teoman Peköz

CCFSS Library (1939 - present)

INTRODUCTION The results of the first phase of an experimental investigation are presented in this report. The objective of this investigation is to study the applicability of a theoretical approach developed at Cornell and implemented in a computer program developed by T. Pekoz for Diaphragm Braced Channel and Z-Section Purlins. In this phase of the experimental program three "full-scale" assemblies were tested under simulated wind-uplift loading. In addition, several supplementary tests were carried out to determine various physical parameters utilized in the analytical solution. The reported results are restricted to those tests that have direct bearing on correlating the test …


Tentative Load And Resistance Factor Design Criteria For Steel Beam-Columns, M. K. Ravindra, Theodore V. Galambos Oct 1974

Tentative Load And Resistance Factor Design Criteria For Steel Beam-Columns, M. K. Ravindra, Theodore V. Galambos

CCFSS Library (1939 - present)

Nominal design equations and reai•tance factors are developed for steel beam-columns as part of Load and Resistance Factor Design criteria for steel buildings. The resistance factors are derived from principles of first-order probability theory using calibration to present designs.


Design Of I-Shaped Beams And Columns With Diaphragm Bracing, S. J. Errera, T. V. S. R. Apparao Jul 1974

Design Of I-Shaped Beams And Columns With Diaphragm Bracing, S. J. Errera, T. V. S. R. Apparao

CCFSS Library (1939 - present)

Cold-formed steel panels often are used as wall sheathing, roof decking or floor decking in steel framed buildings or pre-engineered metal buildings. Diaphragms formed by interconnecting these panels have considerable in-plane shear resistance, and can be utilized as bracing against buckling for individual members of a steel frame. For wall columns the diaphragm may be either directly attached or connected to girts which in turn are connected to the columns. A procedure is presented for the design of I-section beams and columns with diaphragm or diaphragm-girt bracing. The procedure is based on the ultimate load capacity of fully braced members, …

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 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.


Recommended Procedures For Conducting Pull-Over, Pull-Out And Single-Shear Tests Of Mechanical Connections, John Fraczek, George Winter, Teoman Peköz Dec 1973

Recommended Procedures For Conducting Pull-Over, Pull-Out And Single-Shear Tests Of Mechanical Connections, John Fraczek, George Winter, Teoman Peköz

CCFSS Library (1939 - present)

1. SCOPE 1.1 These methods cover procedures and definitions for the mechanical testing of joints formed by connecting a cold-formed steel member to a cold-formed or hot-rolled steel member with one or more mechanical fasteners. The purpose of these procedures is the determination of the load capacities of the joints so formed. 1.2 The term "mechanical fastener" or "fastener" shall be defined as any mechanical device used in the connection of two or more members, inclusive of such devices as bolts, tapping screws and rivets but exclusive of welds and adhesives. 1.3 The following mechanical tests are described: Sections Pull-Over …

Local And Overall Buckling Of Cold-Formed Compression Members, John T. Dewolf, George Winter, Teoman Peköz Nov 1973

Local And Overall Buckling Of Cold-Formed Compression Members, John T. Dewolf, George Winter, Teoman Peköz

CCFSS Library (1939 - present)

The objective of this investigation has been to develop information on the interaction between local plate buckling and overall column buckling in cold-formed compression members with a view toward possible improvement of those provisions in the American Iron and Steel Institute Specification for the Design or Cold-Formed Steel Structural Members concerned with column design. Two types of compression members were tested: two channels connected flange-to-flange to form a box section, and two channels connected back-to-back to form an I-section. For both of these shapes, the stress at which local buckling occurs and the postbuckling strength were varied by varying the …
