Plates and Shells with Crack-Like Flaws
The formulation of new hierarchial finite elements for the analysis of laminated plates and shells in the presence of flaws are discussed. The performance of the elements is evaluated...

p-Version of FEM and Shape Optimal Design
This paper presents some research results obtained recently in using the p-version of the finite element method (FEM) for shape optimal design. It is shown that the p-version 2-D elastic...

Buckling of Tapered Columns by P-Version of F.E.M.
The local, distortional, overall, and interactive buckling of tapered, thin-walled members under axial compression and flexure are considered by using three-dimensional models based on...

An Object-Oriented Model for Building Design and Construction
This paper describes the initial work done in developing a modelling environment which captures both functional and spatial aspects of a building, abstract and detailed descriptions, and...

Discrete Optimization of 3D Steel Frames
The purpose of this paper is to report the results of the application of a general discrete optimization procedure to the design of a realistic, three-dimensional steel building frame....

Vector Optimization of Structural Systems
In this paper the basic ideas of vector optimization are presented, and both the weighting and constraint methods are applied to vector optimization of truss systems by minimizing the...

Fast Track Paving May Offer Applications to Structures
'Fast Track' is a technique that permits portland cement concrete pavements to be opened to traffic in a day or less after they are poured. The method has been...

Numerical Evaluation of Energy Release Rates
Numerical studies are described that evaluate the total energy release rate, GT, for quasi-static, Mode I cracks using two-dimensional finite-element...

Inspection Strategies for Offshore Structures
The fatigue limit state is the governing limit state for the structural dimensions in several parts of offshore structures. Prediction of the fatigue life of tubular joints and other welded...

Fast-Track Concrete Paving
Well known for its corn production, the State of Iowa has been seeding a new product for the past several years. 'Fast Track' concrete has grown along the edge...

Early Opening of Concrete Pavements to Traffic
Current practice for opening slab replacements and full-depth repairs to traffic ranges widely from 2 hours to several days. A rational and simple procedure is urgently needed for determining...

Analytical Model for RC Panels Under Cyclic Load
There are several existing constitutive laws for cracked concrete and steel in RC developed in Okamura laboratory. These models have been developed and verified through reversed uniaxial...

Development of Analytical Models for Reinforced Concrete
A computer program called WCOMR was developed to analyze the characteristics of RC walls subjected to reversed cyclic loading. The WCOMR comprises RC element idealization described by...

A Structural Analysis Model for Timber Shear Walls
A numerical modelling procedure for the non-linear analysis of timber shear walls is presented. The model includes the non-linear behavior of the connectors between the sheathing and framing,...

Overview of Programs at Sandia National Laboratories
This paper presents on overview of the containment integrity programs at Sandia National Laboratories. Companion papers at this conference give greater details about the construction,...

Containment Model ? Test Program and Results
Sandia National Laboratories (Sandia) completed the testing of a 1:6-scale containment building for a Light Water Reactor (LWR) in July 1987. The containment building was made of reinforced...

An Overview of the Round-Robin Analysis of the 1:6-Scale Reinforced Concrete Containment Model
The results of nonlinear structural analyses of a 1:6-scale reinforced concrete model, which were independently conducted by ten different organizations, are briefly described and compared...

Aerodynamic Modeling of Chimneys
The wake induced acrosswind behavior of circular cross-section structures, such as industrial chimney, has been studied for many years using wind tunnel models. Due to the relaxation of...

Tuned Liquid Damper and Its Application to Tower-Like Structures
A new kind of damper, Tuned Liquid Damper (TLD) relying upon motion of, shallow liquid in a rigid container for absorbing and dissipating the vibrations energy is explained. The performance...

Seismic Response of Multistory Building Structures With Flexible Floor Diaphragms
