Obtaining Highway Engineering Services From Professional Engineers In Private Practice, R. E. Shaver, John W. Hutchinson

Kentucky Transportation Center Research Report

Current state highway department procedures for obtaining private professional engineering services are reviewed and summarized as part of a study of the consulting engineering contracting policy and procedures of the Kentucky Department of Highways. The current bases used by state highway departments for establishment of fees for the professional services of Engineering Consultants, Attorneys, Right-of-Way Appraisers, Right-of-Way Buyers, and Architects are summarized, by state, in Table 1. In general, the consulting engineering contracting practices followed in Kentucky were found to be a combination of the most desirable points of procedure represented in the replies received from other state highway departments …

A General Study Of Highway Construction Materials Jefferson County (A Pilot Study), James H. Havens, Robert C. Deen

Kentucky Transportation Center Research Report

The general geology of Jefferson County is very similar to that of other counties lying along the fringes of the Outer Bluegrass area -- that is to say, bedrocks are more-or-less horizontally stratified and consist principally of limestones and shales. The present topography is largely the result of erosion; the soil mantles are residual products of weathering of the uppermost stratum of bedrock or shale (as the case may be).

The unique features of the area are associated with the Ohio River and outwashes resulting from encroachments of two glaciations. The toe or southern boundary of ice did not cross …

Torsional-Flexural Buckling Of Thin-Walled Open Sections, Pen J. Fang, George Winter

CCFSS Library (1939 - present)

INTRODUCTION Compression members with thin-walled open sections, because of their low torsional rigidities and because their cross-sectional configuration is such that the centroid and the shear center often do not coincide, can buckle at loads well below the Euler load by interaction of torsion and bending. Fast expanding applications of such sections in civil and architectural engineering call for an extensive investigation of torsional-flexural buckling. Basic theory of torsional-flexural buckling is treated by a number of authors, I,2 and simplifications of the basic theory in the elastic range for the design purposes together with some test results were reported previously. …

The Performance Of Beams And Columns Continuously Braced With Diaphragms - I, Gordon P. Fisher, S. J. Errera

CCFSS Library (1939 - present)

When properly attached, shear-rigid light-gage metal diaphragms, such as roof decking or wall sheathing, can be very effective as lateral bracing for slender columns and beams. At present, limited design use is made of this fact, because of inadequate information on the effectiveness and reliability of such bracing. In this thesis, previous theory on the stability of Isection beams and columns braced with shear-rigid diaphragms has been extended. Two energy methods are used, one employing the Euler-Lagrange conditions from the calculus of variations, and the other the Rayleigh-Ritz method. The problem initially considered is that of an I-section beam-column eccentrically …

Evaluation Of Chemical Composition And Particle Size Gradation Of Evaporation-Reducing, Monolayer-Forming Materials, Vaughn E. Hansen, Gaylord V. Skogerboe

Reports

Initial field testing began shortly after the arrival of materials in August, 1964. The field experiments were designed to evaluate the effects of the long-chain alcohol C20 and particle size gradation on the effectiveness of evaporation retardants when applied by aerial techniques. The materials which were tested at Utah Lake are listed below.

Structural Performance Of Light Gage Steel Diaphragms, Larry D. Luttrell, George Winter

CCFSS Library (1939 - present)

Light gage steel roof, wall, and floor systems may be used to transfer in-plane shear forces from one part of a framed structure to another, leading to reduced loads in parts of the structure. This is particularly noticeable in buildings having rigid end walls and under lateral loading. The diaphragms transfer forces from the interior frames into the foundation through the rigid end walls, resulting in lower loads for the interior frames. The amount of force transfer is dependent upon the in-plane shear strength and is particularly sensitive to the shear stiffness of the diaphragm. The results from some 60 …
