Historic Seawalls of the Boston Harbor, Massachusetts Region: Evolution, Construction and Repair
The earliest seawalls in the Boston region were of crib construction. Cobb cribs had an open framework and could readily be floated into position and sunk with rock from local sources....
The Crown and the Curtain Wall
Crowning the complex curtainwall of an 870 ft concrete tower with a 150 ft high crown of aluminum masts in concentric rings above the 60th floor required ingenuity and extraordinary cooperation...
Gabions and Geogrids
The century-old gabion concept can be improved upon by adding geogrid reinforcement to the soil embankments the gabion wall is designed to support. The grids add stability to the embankment...
Design Loads for Sloshing in TLP Pontoons Tanks
Impact of fluid inside the Auger TLP ballast tanks on tank walls was investigated and changes made to the structural design in an accelerated fashion through the use of model testing....
The Caisson Solution
Detroit is expanding its wastewater treatment plant to drastically reduce combined sewer overflows. The expansion, however, is being done on an extremely congested 4 acre tract of land...
Rebuilding an Illusion
A dam that controls the level of Fall Lake, a major entry to the Boundary Waters Canoe Area Wilderness of northern Minnesota had to be rebuilt, but federal agents barred constructors from...
Cellular Sheet-Pile Floodwall
Williamson, W. Va., flooded 37 times in this century, will soon be guarded by a $41 million, 4000 ft floodwall being built by the U.S. Army Corps of Engineers. A series of 41 circular...
Low-Rise Shear Wall Failure Modes
A summary of the data that are available concerning the structural response of low-rise shear walls is presented. These data will be used to address two failure modes associated with shear...
Building Beneath Boston
Up/down construction is a method in which a project's substructure and superstructure are simultaneously built. The substructure's wall, column and foundation...
Computer-Assisted Geometric and Kinematic Analysis of Subsurface Faulting in the Vicinity of Yucca Mountain, Nevada, Using Balanced Geologic Cross Sections
Computer-assisted geological cross section balancing methods are used in the geometric and kinematic analysis of subsurface structures in the vicinity of Yucca Mountain, Nevada, including...
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...
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...
Finite Element Approximation to Heat Transfer Through Construction Glass Blocks
The purpose of this study is to investigate the heat transfer through combined solid and fluid media, taking into account the interaction between the solid and the fluid. The main example...
A Simulation to Noise Barrier
The problem related to noise barrier is simulated by a still, single frequency, three dimensional sound source located within two parallel screens with rigid back walls. The solution of...
Myocardial Wall Stress: A Clinician's View
Definition of left ventricular (LV) wall stress is a parameter which has a valid application in clinical medicine. This paper discusses this application as it pertains to various cardiac...
Large Deformation Analysis of Cardiac Structures
The finite element technique can be used to simulate the response of the cardiac structures that have complex shape and geometry and nonlinear material properties. This paper enumerates...
Assessment of Left Ventricular Flow Dynamics Using the Finite Analytic Method: Potential for Clinical Applications
Left ventricular (LV) function is traditionally assessed from chamber wall motion, rheological properties of the myocardium, and invasive measurements of chamber pressure. In order to...
Spherical Shells with Nonuniform Rigidity
An iterative finite difference technique is presented in this paper for the analysis of axisymmetric spherical shells with variable wall thickness. The proposed method of solution is based...
Inspection Goes High Tech
Many believe that rehabilitation of the existing infrastructure�not net construction�will dominate the 1990s. Therefore, accurate condition assessment is crucial, since public works agencies...
Hurricane Retrofit
Houston's Sheraton Hotel and Convention Center has been retrofitted to protect it from panel pop-out (separation from building curtain walls) and curtain-wall separation from...
