Step-by-step numerical integration method developed and applied to determination of response to digitized record of N-S component of the 1940 El Centro earthquake of a typical New Zealand...

Nonuniform Torsion of Steel Beams in inelastic Range
Tests on five 6 in. × 6 in. rolled wide-flange steel beams of 76 in. length were performed by subjecting them to concentrated torques in the span. The tests were carried to very large...

Equivalent Viscous Damping for Yielding Structures
The paper treats the application of the concept of equivalent viscous damping to the steady-state response of simple yielding structures subjected to sinusoidal excitation. Using the elasto-plastic...

Elasto-Plastic Bending of Rectangular Plates
A method is given to analyze the bending of rectangular plates loaded beyond the elastic limit. Plastic strains are treated as equivalent lateral loads and edge moments. The method can...

Discrete Model Analysis of Elastic-Plastic Plates
By invoking the usual assumptions of the classical theory of plates and shells, a discrete flexural model of a plate is deduced from a discrete model of three-space solids. All the flexural...

Buckling of Inelastic, Tapped, Pin-Ended Columns
A numerical method for finding buckling loads of pin-ended tapered columns which are elastic, elastic-plastic, or completely plastic is presented. An enclosure theorem is used to find...

Limit Analysis of Continuous Prestressed Beams
With the aid of an electronic computer, exact moment curvature M-φ relations are obtained for a wide range of eccentricities and prestressed steel ratios. Ultimate moments and ultimate...

Elasto-Plastic Analysis of Reinforced Plates
An extension of the available theories for the analysis of rectangular two-way reinforced metal deck plates into the large deflection, elasto-plastic stress region is described. A procedure...
