Buckling Of Diaphragm-Braced Columns Of Unsymmetrical Sections And Application To Wall Studs Design, Amir Simaan, George Winter, Teoman Peköz

CCFSS Library (1939 - present)

Lateral bracing has a significant effect on increasing the buckling load of compression members. In the case of wall stud construction, such bracing is provided by wallboards directly attached to the stud along its length and results in increasing the load carrying capacity significantly. The objective of this investigation is to study the behavior of singly symmetric sections braced by shear diaphragms and to apply the theoretical findings verified by experimental results to the design of wall studs. In the present investigation the shear rigidity as well as the rotational restraint of the diaphragm are considered. Using an energy approach, …

Response Of Orthotropic Bridge Decks To Highway Loadings, Harry Morris Rexin

Dissertations and Theses

This thesis documents the fabrication, testing techniques, and response of a plastic scale model of an orthotropic bridge deck. To economically investigate a two-lane steel bridge deck, plastic Acrylic^R was used as a modeling material. Welds were simulated with dichloromethane, a capillary action solvent, and PS-30, a polymerizable cement. Deflections were measured with laboratory dial guages while strains were monitored with strain guages mounted on the deck.

The response of the deck to AASHO vehicle axle loads was compared with a discrete element computer program used to analyze orthotropic bridge decks continuous over flexible supports. Results indicate good correlation …

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. The 1973 Annual Technical Session was held on May 2 and 3 at the Los Angeles Hilton Hotel in Los Angeles, California. Sixty persons attended the Session and thirty-three papers were delivered. A panel discussion on "Frame Stability Under Seismic Loading" was held in the evening of May 2, 1973. Panelists were E. …

Tests On Field Welded Puddle And Fillet Weld Connections, R. S. Yarnell, Teoman Peköz

CCFSS Library (1939 - present)

INTRODUCTION This report contains the results of tests on 122 field welded connections. Most of the specimens are approximately the same as those that were shop welded previously and tested. The results of tests on shop welded specimens are given in Ref. 2. Those field welded specimens that do not correspond to the shop welded specimens are indicated in Table lA. Except as noted, all notations, variables, weld configurations and procedures are identical with those in Ref. 2. All specimens were tested in a hydraulic test machine under monotonically increasing slowly applied tensile force. This report differs from Ref. 2 …

Diaphragm Braced Thin-Walled Open Sections And Design Of Wall Studs, Amir Simaan, Teoman Peköz

CCFSS Library (1939 - present)

INTRODUCTION Cold-formed steel wall studs generally are I, Z or channel shaped with or without stiffening lips, and with webs perpendicular to the plane of the wall. Because of their configuration and dimensions, these sections are quite unstable by themselves. However, the stability and, hence, load-carrying capacity of such studs are increased substantially once they are connected to the wallboard material. The main function of the wallboard is that of enclosure, but it serves also as a bracing system for the studs. Gypsum board, vegetable fiberboard, tempered board or plywood are commonly used wallboard materials. Such boards are connected to …

Diaphragm Braced Channel And Z-Section Beams, George Winter, Nuri Celebi, Teoman Peköz

CCFSS Library (1939 - present)

PREFACE Cold-·formed channels and Z-shapes are widely used as purlins supporting roof surfaces which consist of light-gage steel panels or other material. If the panels are interconnected to form diaphragms, they brace the purlins and increase their carrying capcity sizeably. It is the purpose of this investigation to explore this bracing effect and provide tools for its utilization in~design. The author wishes to express his gratitude to Professors George Winter and Teoman Pekoz, Project Directors. Their suggestions, criticism and guidance made this work possible. The research project covered by this report was sponsored at Cornell University by the American Iron …

Cold-Formed Steel Structural Elements Subjected To Time-Dependent Loading, Charles G. Culver

CCFSS Library (1939 - present)

This report summarizes the results obtained from a comprehensive study of the behavior of thin-walled, cold-formed members subjected to impact or shock loading. The influence of local buckling and the concept of effective width in the elastic post-buckling range on the dynamic response of these members is described. Analytical and experimental results for thin compression elements, beams and columns are discussed. Comparisons between the analytical and experimental results are presented. Application of the results obtained from this research to practical situations involving impact or shock loading of cold-formed members is also discussed.

Study Of Cold-Formed Steel Structural Members Made Of Thick Sheets And Plates, William M. Mckinney, Victor A. S. Liu

CCFSS Library (1939 - present)

INTRODUCTION In steel design, the Specification for the Design of Cold-Formed Steel Structural Members l issued by the American Iron and Steel Institute has long been used for structural members cold-formed to shape from steel sheet or strip used for load-carrying purposes in buildings and other thin walled steel structures. Even though no thickness limitation was included in previous editions of the Specification, 2,3, the thickness of material used in the cold-formed steel construction was often limited to about 1/4 inch because the maximum thickness of steels used under all ASTM Specifications listed in Section 1.2 of the AISI Specification …

CCFSS Library (1939 - present)

INTRODUCTION The purpose of the present investigation has been to study the behavior of symmetrically welded connections having different weld configurations. As shown in Fig. la, the specimens were fabricated by butting two plates (CP) which were connected by welding cover plates AB and CD on two sides of CP. The fabricator supplied different types of welded connection specimens, sketched in Figs. la to If. A total of 115 specimens were tested in tension under monotonically increasing static load. Basic variables considered in the design were: (a) thickness and the shape of the cover plates, and (b) weld size and …

The Analysis And Behavior Of Thin-Steel Hyperbolic Paraboloid Shells, Peter Gergely, P. V. Banavalkar, J. E. Parker

CCFSS Library (1939 - present)

An extensive experimental and analytical investigation of thin-steel hyperbolic paraboloid (hypar) structures was carried out to provide design information. As a result of this work, empirical data is provided regarding the behavior of such structures and computer programs are presented for the analysis of thin steel hypar structures. Hyperbolic paraboloid structures possess a unique combination of structural and architectural properties; some of them are the following: 1) Due to the double curvature of the surface the internal stresses in the deck are generally low and the deflections are small. 2) Since a hypar surface can be generated by straight lines, …
