Ups and Downs in Chicago
The Chicago Title and Trust Center�a 50-story mixed-use complex which opened late last year�offers 1.3 million sq ft of above-grade space, and three levels of below-grade parking. The...
The Design and Construction of Shuikou Project RCC Diversion Wall
Shuikou Hydroelectric Project, currently under construction on the Minjiang River in the People's Republic of China is a concrete gravity dam having a maximum height of 101...
Design of Protective Dunes at Dam Neck, Virginia
Dunes act as a primary coastal defense against inundation in the Netherlands and the Dutch Government has devoted considerable effort towards development of reliable procedures for the...
Articulating Block Mat Revetment for Whaler's Village
The desire of homeowners to live along the California coastline presents the engineer with many unique design opportunities and constraints. Housing built atop coastal cliffs and bluffs...
Dutch Experience on Design of Dikes and Revetments
The increased demand for reliable design methods for protecting structures has resulted in The Netherlands in preparing a set of design guidelines for design of dikes and revetments. The...
Sandbridge Virginia Oceanfront Seawall Arbitration Hearing: Some Lessons Learned for Coastal Engineers
A group of beach property homeowners claimed that their new oceanfront seawall was defective in design. A beefed-up design cost about $1.3 million more and they sought this amount from...
Retrofitting a Landmark
A decade after it was abandoned, a famous sixty year old tire factory has been rehabilitated as part of a $118 million adaptive mixed-reuse commercial-office mall known as the Citadel....
Damage Dependent Micromechanics in Metal Matrix Composites
A computational approach is used herein to model the effects of processing induced thermal residual stresses on radial, hoop, and shear stresses at the fiber/matrix interface in a continuous...
Mechanical Characterization of the Soft Tissue in Horse Hooves
The laminar corium tissue of the equine distal digit (or horse hoof) has been tested uniaxial tension. The laminar corium tissue lies between the hoof wall and the underlying bone of the...
Relationships Between Error Estimation and Adaptive Computations in Strain Localization
In this work, the a posteriori error estimates and the h mesh refinement techniques using hierarchical finite element shape functions are tailored for numerical simulations of strain localization...
Analysis of Internal Discontinuities in Geo-Materials
A new approach for modeling localized deformations is proposed. This approach uses an interface element to model the shear band. A successful capture of the kinematics of a failure mechanism...
Computer Simulation of Direct Shear Test
This paper presents a pilot study of a computer simulation of direct shear test on sands using the Discrete Element Method. The numerical test setup is described first, which is followed...
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...
Stress Wave Interaction in Finite Beam on Elastic Foundation
The short-time behavior of a finite Timeshenko beam on a Winkler foundation subjected to step and impulse loadings is presented. The transient behavior was analyzed by using the method...
Shear Flow Between Walls in Relative Motion
The paper reports on experiments on Couette flow, i.e., the shear-induced flow between surfaces which are in motion relative to each other. The novel aspect of the work is the appearance...
Harmonic Excitation of an Unconstrained Saturated Particle Bed
Past research on the flow of concentrated cohensinless mixtures have historically emphasized steady or quasi-steady motions while dynamic effects have received little attention in comparison....
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...
Leakage Characteristics of the St. Jude Heart Valve
The requirement for anticoagulant therapy in patients implanted with mechanical heart valve prostheses is well known. A plausible explanation for this requirement is that the leakage flow...
Intra Vena Cava Balloon Pumping
An innovative prototype intravenous hollow-fiber oxygenator was developed in 1984 by B.G. Hattler. The device consisted of a microporous, hollow-fiber membrane oxygenator inserted into...
The Effective Stress Path for Soil at High Pressure
The effect of increasing stiffness in the soil skeleton on the effective stress path in undrained triaxial compression tests is experimentally examined and found to not be significant....
