On the Influence of Seismically Induced Residual Forces on Bridge Abutment Design
The seismic design of bridge abutments depend on the anticipated movement of the abutment during the design earthquake. For seat-type abutments in which the backfill resistance can be...
Wind Cross-Spectrum Effects on Long-Span Bridges
This paper discusses current analysis for long span bridge response based on wind components. The authors summarize the development of techniques which take such components into account,...
Analytical Studies on the Seismic Response of Lead Rubber Base Isolated Bridges
Highlights of a study related to the response of base isolated bridges are presented. Four different analytical models are developed and used to evaluate the response of base isolated...
Wave Interaction with Fluid Mud in Rectangular Trench
Wave interaction with fluid mud in a rectangular trench is studied theoretically based on small-amplitude wave theory. The problem was formulated using the Voigt model for an viscoelastic...
Nonlinear Shoaling and Impact of Waves on Coastal Structures
A two-dimensional fully nonlinear potential flow model is used to calculate shoaling of solitary and enoidal waves over a sloping bottom and interaction with submerged or emerged coastal...
On the Role of Experimental Mechanics in Assessing the Performance of Concrete
The role of experimental mechanics in material characterization, design, construction, performance evaluation, repair, rehabilitation and finally destruction of concrete structures is...
Use of Hierarchical Lattices for Predicting the Fluid or Stress Transfer in Concrete
Hierarchical lattices are used to study the influence of local disorder on the transfer of properties (stresses, strains, permeability) from the micro-scale to the macro-scale. They are...
Two Basic Concepts in Offshore Engineering
Two concepts are developed which lead to an improved understanding of the characteristics of the wave forces that act on deep-water, jacket-type offshore structures. The first concept...
3D Frequency Domain Analysis of Offshore Structures
This paper reports the application of three-dimensional (3D) frequency domain computational tools to the dynamic analysis of offshore structure systems. Previous applications of 3D frequency...
Responses of Bilinear and Impacting Systems Subjected to Regular Waves
The dynamic responses of bilinear and impacting oscillators subjected to harmonic loadings are investigated. Differing from previous studies in which bifurcation diagrams were developed...
Cylindrical Shell Redesign by Large Admissible Perturbations
Redesign (or inverse design) is the problem of defining an objective structural State S2 from its specifications and the known baseline State S1. The large admissible perturbations approach...
Wavelet Transform Analysis of Several Transient or Nonstationary Phenomena in Engineering Mechanics
Several examples of the use of a wavelet transform in the analysis of transient events in mechanical systems are provided. The transform has the advantage over other transient analysis...

Numerical simulations of three-dimensional viscous liquid sloshing in rectangular containers were carried out using an improved volume of fluid technique in conjunction with the Navier-Stokes...
Wave Propagation in Fluid Loaded Periodic Structures
Periodic structures, such as rib stiffened plates or cylindrical shells, are frequently used as major structural components in naval and aerospace applications. For these applications,...
Nonlinear Behavior of Thin Slender Free Surface Non-Newtonian Elliptical Rings
This paper analyzes the nonlinear motion of a slender concentric thin elliptical ring of an incompressible, non-Newtonian fluid. This study includes the physical effects of surface tension,...
Landslide-Generated Waves in Reservoirs
This paper investigates surge waves generated by landslides in reservoirs. The Navier-Stokes equations with complete viscous conditions at the free surface are solved numerically for the...
Flexible Porous Breakwater
This is a theoretical study of the reflection and transmission of linear waves by a flexible, porous and thin beam-like breakwater held fixed in the sea bed. The breakwater is idealized...
Refined Analysis of Load Distribution Factors for Bridges
This paper presents a new approach for calculating the distribution factors for slab-on-girder bridges. This method considers the coupling of longitudinal and transverse effects. The governing...
