Warping Stresses in Slabs of Reissner Foundation
Warping stresses have been evaluated in circular and strip concrete slabs resting on the ground by idealizing the foundation medium by the Reissner foundation. Linear temperature variation...

Matrix Force Analysis of Thin-Walled Structures
The Bernoulli's hypothesis of plane cross sections remaining perpendicular to the deformed center line does not adequately approximate the deformation due to the torsion of...

Torsion Analysis of Heavy Box Beams in Structures
Heavier box sections with thicker walls without the need of longitudinal stiffeners are widely used to resist combined torsion and bending loads in machines such as earth-moving and mining...

Tolerable Settlements of Steam Turbine-Generators
The foundations for one type of machine, the modern steam turbine-generator, are studied by relating observed differential settlements with operational records to determine tolerable distortions....

Box Girder Model Studies
An experimental study of the stresses in a box girder subjected to concentric and torsional loading configurations is described. Tests were conducted on a plexiglas model to examine the...

BED Analogy for Analysis of Box Girders
An analysis for a box girder cell with deformable cross section and flexible interior diaphragms is developed using an analogy to the theory of beams on elastic foundations. The analogy...

Multiple Folded Plates with Various End Conditions
A simple method for the analysis of multiple folded-plate systems is presented based on the ordinary folded-plate theory. The procedure may be applied to any single-span system having...

Simplified Design for Flume Inlets
The subject of contractions for open channel flow at subcritical velocity is studied. In particular, the design for flume inlets is critically examined. It is suggested that a gradual...

Stability of a Bar Under Eccentric Follower Force
A uniform cantilevered bar subjected at the free end to an eccentric, compressive follower force is considered. It is shown that, for cross sections having two axes of symmetry and vanishing...

Torsional Response of Tapered I-Girders
The differential equation of torsion is derived from first principles for tapered I-girders. It accounts for St. Venant, warping, and secondary stiffnesses. A number of boundary conditions...

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...

Elastic Torsional Analysis of Irregular Shapes
A direct stiffness (finite element) solution method for the torsional analysis of shafts is presented. The technique is applicable to prismatic shafts (linear elastic material) of arbitrary...

Differential Settlement at Selfridge Air Force Base
Structural damage of buildings is noted after 25 yr of satisfactory service. Surveys for a 6-yr period have shown movements that tipped and warped floors and walls. Calculations show that...

General Solution of Space Frameworks
Slope defection gyration method is applied to solution of space frameworks with members in any direction, under any system of loads; method provides set of simultaneous equations that...

Analysis of Concrete Slabs on Ground
New theory for calculating stresses and deflections in concrete slabs on ground for buildings and homes, or concrete pavements for highways and airports; theory accounts for weight, superimposed...
