Postbuckling Response of Doubly-Curved Shallow Panels Under Complex Loading Conditions
The static postbuckling of laminated doubly-curved shallow panels subjected to the complex action of a system of in-plane compressive edge loads and a transverse pressure field is investigated....
Analysis of Composite Panels Using Newton's Method
Postbuckling response prediction of composite panels using Newton's method will be discussed. The traditional approach of nonlinear finite element analysis is to use a Newton-Raphson approach...
Snap Buckling of a Delaminated Layer in a Composite Cylinder
We investigate snap buckling of a thin delaminated layer on the inner surface of a contracting thick cylinder. Finite-deflection solutions of the layer with or without considering the...

The paper presents an approach to the analysis of axisymmetric vibrations of thick-walled specially orthotropic multilayered cylindrical tubes. The first part of the paper is concerned...
Thermal Stresses in Piezoelectric Materials: A Boundary Integral Formulation
With the increasing use of piezoelectric materials in electromechanical devices which are often required to function in thermally hostile environment, thermal stresses and their influence...
Implementation of a Viscoplastic, Kinematic Hardening Constitutive Model for Impact Prediction
This paper reports on a preliminary study to determine the significance of the Bauschinger effect on modeling impact and other large deformation events. Such events have significant implications...
Design of Mat Foundation for Egg Shape Digesters
Two levels of ground motion, the Maximum Probable Earthquake and the Maximum Credible Earthquake, were considered in designing the 2.5 million gallon egg shape digesters and their combined...
Concrete Buildings in Regions of High Seismicity
Structural systems for multistory concrete buildings in regions of high seismicity are reviewed. The suitability and certain practical aspects of the systems are discussed. A Uniform Building...
Seismic Design of RC Structural Walls with Unsymmetrical Cross-Sections
An overview of seismic design issues and current experimental research for walls with unsymmetrical cross-sections is presented. The experimental studies include approximately 1/4 and...
Physical Model Tests of Dolos Impact Stresses
An on-going experimental study to determine impact stresses and static nesting stresses in instrumented large scale model dolosse is described in this paper. Seven dolosse were instrumented...
Composite Walls as Shear Elements in Tall Structures
This paper describes a system of composite walling that can be used as a lateral load resisting system in tall structures. The composite walling comprises two skins of profiled steel sheeting...
Comprehensive Reliability Analysis of Prestressed Concrete Beams
Using second moment methods, the reliability with respect to several limit states for seventy three prestressed concrete beams is assessed. These beams that are extensively used in the...
Strut-Tie Model Design of Disturbed Regions in Concrete Structures
The design of disturbed (highly non-linear behavior) regions in concrete structures is illustrated using strut-tie approach. The use of this approach assisted with interactive computer...
Behavior of RC Beams under Sustained Load
Experimental results of eight reinforced concrete beams under 3-month's sustained load, with the ratio of shear span to depth equal to 2.5, are reported. It is shown by tests that the...
Design of Lateral Steel in Columns
Lateral steel in columns is generally required for shear resistance, confinement of concrete and prevention of buckling of longitudinal bars. This paper is limited to the design of lateral...
The Canadian Approach in the Design of Wood Structures: Conversion to Limit States Design
During the early 70's, the National Building Code of Canada (NBCC) established the principle that structural design be carried out using the limit states design (LSD) method. The technical...
LRFD Provisions for Wood Bridges
A project to develop a load and resistance factor design (LRFD) edition of the American Association of State Highway and Transportation Officials (AASHTO) Standard Specifications for Highway...
The Use of Coda Waves for Characterizing the Site Effect on Strong Ground Motion
The well established separability of source, path and site effects on coda waves of local seismic events offers the most effective means for determining the site amplification factor empirically....
Test Experience with Heavy Angle Dead End Lattice Transmission Towers
During the past three years, the Electric Power Research Institute's Transmission Line Mechanical Research Center has conducted full scale tests on three 500kV heavy angle dead end lattice...
Metal Truss Plates: Less than Full-Depth Penetration and Shear Buckling
This paper presents the results of two experimental studies on metal truss plates which are used to join members of wood trusses. The first study investigated the effect that less than...
