Finite Element Analysis and Design of Plywood Shear Walls
An integrated procedure for the analysis and design of rectangular plywood shear walls is presented and illustrated. The analysis is done using an in-house finite element program with...
Boston's Sewage Outfall
The centerpiece of the Boston Harbor cleanup plan will be the sewage plant on Deer Island, which will treat water from 43 municipalities in the Boston metro area�500 mgd to start. In order...
Remote Sensing for Seismic Hazard Assessment of a Proposed Nuclear Power Station, North Wales, UK
During the seismic hazard assessment for a proposed nuclear power station in North Wales, UK, a remote sensing study was carried out in conjunction with other, wide-ranging geological...
New Jersey Department of Transportation Bridge Scour Evaluation Program
The New Jersey Department of Transportation's (NJDOT's) newly initiated bridge scour investigation program will assess the vulnerability to failure by scour of...
Field Investigation for Leachate Flow in a Landfill
Field investigation for leachate flow was done for the Fresh Kills landfill at Staten Island, New York. The leachate monitoring program included data collection from the field for a six...
AI Development Environment for the Maintenance of Existing Buildings
A specific structural typology is considered with a deep expertise available on the subject. The 'state of health' of a single building is assessed by an expert...
Finite Element Studies of Block Shear for Structural Tees
Structural tees are commonly used as tension members. As a first step toward testing the adequacy of the current design codes for net section and block shear failures near the connections...
Prediction of Transverse Shear Stresses for Various Isoparametric Thick and Thin Shell Elements
Utilizing three-dimensional equilibrium equations (often referred to as an Equilibrium Method (EM)), an estimation of transverse stresses for fiber-reinforced laminated doubly curved shells...
A Kinematic Hardening and Softening Model of Concrete
In the present paper, a new loading surface calibrated by several typical uni- and multi-axial test curves is proposed. Following the associated flow rule, a relatively simple constitutive...
Inelastic Mechanisms in Dynamically Loaded Ceramics
The dynamic response of ceramic materials has been the subject of intense research in the past decade. In this paper, we succinctly describe a plate impact experiment of a star-shaped...
Laboratory Study of Wave-Current Interactions
Laboratory experiments confirmed the non-breaking blocking of waves by strong adverse current. Data failed to confirm the conservation of action flux....
Chaotic Advection in a Shear Layer
The developing (in time) inviscid shear layer, although not yet in its turbulent regime, displays all the characteristics of chaotic advection. The corresponding Lyapunov exponent is strictly...
Computation of Flow Fields Induced by Hydroplant Releases into Lower Lock Approaches
A turbulence-based computational procedure was developed and applied to the prediction of flow fields in navigation installations induced by hydropower releases. The procedure uses a depth-averaged...
Simulation of Head/Neck Response to -Gx Impact Acceleration
The Articulated Total Body (ATB) model has been developed to predictively simulate the head and neck response by specifying a 2-segment/2-joint system driven at the anatomical thoracic...
Normal and Tangential Contact of Layered Spheres as Models of Joint Contact
The causes of cracking in degenerating cartilage are examined using analytical models of layered elastic spheres in normal and tangential contact. Vertical surface and deep radial cracks...
A Contact Problem Modeling the Squeeze-Film Mode of Synovial Joint Lubrication
A contact problem modeling synovial joint lubrication under squeeze-film conditions is studied. In this model, the thin synovial fluid layer is incompressible and linearly viscous, and...
Dynamic Responses of the Precision Segmented Reflector
This paper concerns a structural simulation effort aimed at studying dynamic responses of the Precision Segmented Reflector when subjected to seismic disturbances. The study results indicated...
Stochastic Seismic Response of Simple Structures
Since, at present, it is impossible to eliminate the various sources of uncertainty related to earthquake loading, it is necessary to better understand their effects on structural seismic...
Dynanmic Stability and Seismic Response of Damped Beams in the Presence of Follower Forces
The dynamic stability and the seismic response of general beams are examined, by discretizing the structure to a set of rigid bars, linked together by means of elastic constraints (Cells...
Effects on Seismic Spatial Variations to Suspension Bridge Responses
The dynamic soil-structure interaction effects and spatial variations of a seismic motion seem to have significant contributions on the response evaluation of a long span suspension bridge....
