Analysis of Continuous Arch Frames
The analysis of continuous arch frames with curved members of constant cross-section and either circular, parabolic or semi-elliptic arch form by means of an extension of the slope deflection...

Tapered Towers with Variable Wall Thickness
The calculation of the tilt and deflections of a tapered tower with variable circular or polygonal cross section can be reduced to the analysis of a cylinder subjected to the same loading....

Torsion in Sections with Open and Closed Parts
A concise method is presented for locating the shear center and investigating torsional stresses in beams that are free to warp and with cross sections consisting of both open and closed...

How Contractors Organize Their Cost Estimating and Control: Progress Report of the Subcommittee on Organization of Estimating Department, Committee on Estimating and Cost Control
A study was conducted using 59 contractors, representing a cross section of the industry, that reports on how to relate estimating to other company functions; how to recruit and train...

Plane-Framework Methods for Plates in Extension
Plane-framework procedures are presented for the analysis of plates in extension. Two different types of rectangular framework models are used to represent a rectangular element of uniform...

Design of Guyed Towers by Interaction Diagrams
A systematic procedure for selecting suitable design dimensions for guyed towers, using interaction diagrams, is presented. The dimensions considered are the cross-sectional area of the...

Flexibility of Axially-Loaded Nonuniform Members
A simple scheme is devised to calculate the stiffness, carry-over factor, and fixed-end moment of nonuniform members under axial load either in tension or in compression. Based on the...

Experimental Stresses in Wide-Flange Beams with Holes
Experimental elastic stresses were determined from tests of simply supported wide-flange beams that had circular and rectangular web holes located at ratios of nominal bending stress to...

Critical Analysis of Open-Channel Resistance
Despite continued progress in the analysis of closed-conduit and boundary-layer resistance, many of the results have been slow to find their way into the hydraulics of open channels. In...

Criteria For Planning and Offshore Pipeline
Alinement, survey and alinement control, burial of pipelines, pipeline crossings, installation of underwater valves, pipe risers, and construction season are examined as they relate to...

Performance of Casting Pipes Under Railroads and Highways: Report of Research Council on Pipeline Crossings of Railroads & Highways
This report presents measurements and observations made of the performance of pipeline casings under railroads in several locations of the United States. Research was conducted to obtain...

Grid-Framework Method for Plates
A grid-framework procedure is presented for the analysis of plates in flexure. A square or rectangular grid model with side and diagonal members is used to represent a similar element...

Inelastic Lateral-Torsional Buckling of Beam Columns
The problem of lateral-torsional buckling in beam columns is studied using an analytical approach to detect the stage at which the inception of this type of instability is imminent. The...

Tilt and Deflections of Tapered Polygonal Towers
The calculation of the tilt and deflections of a tapered thin-walled tower with circular or polygonal cross section can be reduced to the analysis of a cylinder subjected to the same loading....

Report on Pipeline Location
This Report on Pipeline Location is devoted primarily to suggested procedures related to cross-country pipelines: reconnaissance, location,...

Guide To Good Practice For Highway-Pipeline Crossing
The Final Report of the Committee on Pipeline Crossings, Highway Division, is a summary of current (1963) pipeline-crossing practice of state highway agencies. A series of questionnaires...

Strain-Gage Analysis For Uncased Pipeline Crossing: Report of the Research Council on Pipeline Crossing of Railroads and Highway of Pipeline Division
From an analysis of strain gage data obtained by the Association of American Railway Laboratories for simulated highway and railroad crossings by uncased 8 in. and 12 in. pipelines, it...

Development and Use of the Modpares Device: Report of the Research Council on Pipeline Crossing of Railroad & Highways, Pipeline Division
This report develops the modpares device for measuring the modulus of passive resistance of soil. In an attempt to determine the moduli of passive resistance of a wide range of types of...

Time of Travel of Soluble Contaminats in Streams
Time of travel is measured in streams by introducing Rhodamine B dye and detecting its concentration at a downstream cross section by use of a fluorometer. The computation of the necessary...

General Computer Analysis of Beams
A comprehensive method is presented for the machine solution of a number of technically important beam problems. The beam may be uniform or nonuniform in cross section, and the elastic...
