Optimized Models for Predicting Structural Response in Highway Bridges
Optimization techniques are a viable option for modeling bridges that have been field tested. The error between the experimental strains and the analytical strains is minimized by adjusting...
An Electronic Specification for the Earthquake Resistance Design of the Highway Bridges in Pennsylvania
An interactive C program for the seismic design of highway bridges in the state of Pennsylvania is described in this paper. The program was developed in C language on a personal computer....
COMBAT.PC; a New Windows-Based Tool for Three-Dimensional Dynamic Analysis of Multi-storied Building Structures
By some accounts, analytical capability without the power of visualization is little productive; visualization is the tool that will turn computational power into practical results. COMBAT.PC...
Computer Implementation of Seismic Building Codes
The objective of this work is to implement the provisions of building codes current in the U.S. as well as those of other countries for the seismic resistant design of buildings. The work...
Macro-Model for Inelastic Low-Rise R.C. Shear Walls
This paper presents an analytical technique for calculating static and seismic response of low-rise shear wall structures. The displacement response is resulting from bending, shear, and...
Active Control of Structures with Soil-Structure Interaction
The objective of this paper is investigate the effect of soil flexibility on the performance of the active control system for seismic-excited buildings. By using the critical-mode control...
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...
Getting the Lead Out
When officials from Omaha, Neb. announced an ambitious plan to revitalize an abandoned stretch of land along the Missouri River, the land itself presented one of the biggest problems....
Closing Hazardous Landfills
Designing and constructing covers for uncontrolled hazardous-waste landfills can pose some special problems�such as differential settlements as great as 50% of landfill thickness. Under...
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...
Prediction of Runoff-Evapotranspiration to Estimate Leachate Generation in a Landfill
The fraction of precipitation that remains after runoff and surface water evaporation, enters into the solid waste landfill and generates leachate flow at the bottom. A part of the infiltration...
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...
Pilot Drywell Study Pierce County, Washington
Subsurface disposal of stormwater runoff is widely utilized in areas with permeable or porous soils, including the Clover/Chambers Creek (CCC) Basin in central Pierce County, Washington....
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 Evaluation of Thermoviscoplastic Responses of Geomechanical Media Under Finite Deformation
Finite deformation responses of fluid-saturated geological media with thermoviscoplastic solid constituent are evaluated using finite element methods. The coupled nonlinear governing equations...
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....
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...
