A Shear Locking Free Three-Node Triangular Plate Bending Element for Moderately-Thick and Thin Symmetrically Cross-Ply Laminated Plates
A shear locking free three-node triangular plate bending element based on Reissner/Mindlin theory for symmetric general cross-ply laminated plates is developed. The element has total nine...

First-Passage Failure Predictions for Yielding Primary-Secondary Systems
Approximate methods are used to investigate the effect of nonnormality (non-Gaussianity) on the time of first-passage failure for a linear secondary system mounted on a yielding primary...

First Order Importance Sampling Method and its Variance Reduction
This paper proposes an Importance Sampling method for structural system reliability problems with linearized modal failure surfaces. It has the advantage of locating all samples in the...

Response of Mono-Coupled Distributed Parameter Systems to Random Excitation
The random vibration of periodic structures consisting of a multiplicity of closely coupled distributed parameter substructures is addressed. The problem formulation is general, and the...

Interaction Between Soil and a Rigid Foundation in a Layered Medium: A New Analytical Approach
This paper is concerned with derivation of the impedance matrix for the problem of interaction between soil and an embedded rigid foundation in a layered medium. As an approximation, the...

Dynamic Response Analysis of Pile Foundations by Using Variational Calculus
Various approaches have been developed for the frequency-domain dynamic response analysis. The one proposed by M. Novak (1974) is simplest of all and yet produces the results very close...

Experimental and Theoretical Dynamic Compliances of Foundations
An experimental study of the dynamic behavior of surface foundations on granular soils by centrifuge modeling is presented. The test method allows a direct measurement of the complex-valued...

Retrospect and Prospect: Micromechanics
In the mechanics community the term micromechanics is often used to identify scientific efforts in which certain overall macroscopic material response and failure modes are characterized...

Wave Propagation in Solids
The last fifty years have seen the development of a large number of application of the theory of wave propagation in solids to problems of interest to civil engineers. Most notable have...

Postbuckling Behavior of Stiffened Composite Shell Panels
The paper summarizes the current status of an ongoing study on the postbuckling behavior of thick and moderately thick composite stiffened shells. Axially compressed moderately thick panels...

Dynamic Stability of Composite-Material Circular Cylindrical Shells with Orthogonal Stiffeners
The governing equations are formulated for general (axisymmetric or unsymmetric) vibrations of thin circular cylindrical shells of composite material and reinforced with axial (stringer)...

Bifurcations and Chaos in Structural Control
We study a harmonically forced oscillator with nonlinear soft spring subjected to a linear feedback control with time delay. This system can be written as a three dimensional dynamical...

Regularization Methods for Identification of Structural Damage
Generally, various non-unique solutions may be obtained from ill-conditioned equations. Several methods are available to obtain a unique (minimum energy) solution to a modified and thus...

Updating Dynamic Models and Their Associated Uncertainties for Structural Systems
The problem of updating a structural model and its associated uncertainties using dynamic test data is addressed, considering uncertainties which arise from measurement noise, modeling...

Applications of Viscoelastic Damper to Jointed Structures for Seismic Mitigation
Some structures, such as dams, are built with contraction joints that might carry some small tensile stresses. Such joints are expected to open and close during an earthquake. That will...

Anatomy of the Loma Prieta Earthquake Records of Two Steel Buildings Using MIMO System Identification
The Loma Prieta strong-motion records of a 4-story and a 47-story steel building are analyzed using system identification. A time variation study from the 4-story building records reveals...

Effect of Active Control on Closely Spaced Natural Frequencies
Current problems in structural control involve structures with closely spaced natural frequencies (M.J. Balas, 1983). The purpose of this paper is to show how control affects a structure...

The Microstructure of Hardened Cement Paste and Concrete
Concrete is a composite material created from a mixture of a binder (hardened portland cement paste) and a filler (fine and coarse aggregates). Like any other composite material the physical...

Distributed Failure Analysis, Fallacies and Remedies
In the past, two distinctly different approaches - smeared and discrete failure descriptions have been utilised to capture failure mechanisms in solids and structures. These two approaches...

Failure Analysis of Masonry Structures
The use of smeared-crack and interface elements for the analysis of masonry structures is investigated. While a variety of structural problems can be solved with a combination of both...
