Static Response of Reduced Rotation Rope

Shear and Rotatory Inertia Effects on Plates
The purpose of this note is to present the governing nonlinear equation applicable for the large amplitude free, flexural vibration of orthotropic rectangular plates influenced by the...

Tall Frame Analysis by Reduced Generalized Coordinates
The displacements and rotations of joints on the exterior (corner) columns are independently expressed in terms of a set of functions with undetermined coefficients (generalized coordinates)....

Unbraced Length Requirements for Steel I-Beams
Solutions are obtained for inelastic buckling of I-shaped beams of structural steel and the relationship between unsupported length and the extent of flexural deformation sustained at...

Exact Analysis of Class of Ring Segments
An exact analysis for a class of rings whose center lines are cycloids, circles, catenaries, and parabolas based on a simplest elastic thin ring theory has been presented. General homogeneous...

Influence of Shear Velocity on Vane Shear Strength
Comparisons of field and laboratory vane shear strength measurements from geotechnical test areas in the San Diego Trough and Gulf of Maine were made to evaluate the influence of vane...

Single-Angle Welded-Bolted Connections
Full-scale load tests, using combined shear and moment with rotation, of welded-bolted single-angle steel beam connections describe their behavior up to failure for 2-bolts-6-bolts, inclusive....

Minimizing Canal Capacity for Irrigated Rice
Improved formulas are developed for calculating the maximum canal or pump capacity needed for lowland rice rotational irrigation system design. The conventional and modified conventional...

Examination of Plate Post-Buckling Behavior
The main results of a number of previous papers by the writers on plate post-buckling behavior are summarized, and additional results for specific plate problems are presented in the form...

Thin-Walled Curved Beam Finite Element
The generalized displacements and forces at the two nodes of the beam elements are: three translations and their corresponding forces, three rotations and their corresponding moments,...

The Modernization of a Small Hydro Plant
The Cornell Hydro in Northern Wisconsin was torn down, rebuilt, re-equipped and put into profitable operation. After extensive structural modifications to the old plant, three new 10,000...

Effects of P-Δ Moments and Rotatory Inertias on the Behavior of Building Structures

Torsional Stiffness of Twisted Wire Cables
In recent work, expressions were presented for the effective modulus of twisted wire cables consisting of a single lay. Results showed that axial load is nonlinear function of axial strain....

Open Steel Box Sections with Top Lateral Bracing
Top-braced open thin-walled steel box girders under combined bending and torsion were studied. Two model box girders were tested in the elastic range. Analytically, the top bracing of...

Volume and Strength of a Dolos
Precise formula for computing the block volume of dolos, a concrete armor stone for protection of breakwaters and marine structures, is presented with particular emphasis for a heavier...

Further Aspects of Design by PΔ Model
In the PΔ method of design, the secondary forces, produced by the vertical loads acting through the laterally displaced shape of the structure, are included directly in the analysis. This...

Out-of-Plane Vibration of Thick Circular Ring
Dynamic stiffness matrices are derived for the out-of-plane coupled twist-bending motion of a complete circular ring, and which take account of the effects of transverse shear and rotatory...

Safety Factors for Riprap Protection
The merit of a particular riprap design can be represented by numerical value of the riprap safety factor, defined as the ratio of moments resisting particle motion to the moments tending...

Test of Circular Steel Tubes in Bending
A series of tests on 10-3/4in. (270-mm) tubes was conducted to determine the plastic rotation capacity of tubular beams. Six different D/t values ranging from 18-102 were used in the tests....
