Reliability-Centered Management of Wood Transmission Lines
Through implementing reliability-centered management concepts, more cost-effective management of wood pole transmission lines may be achieved. By identifying individual structures and...
Construction Loads on Floors: Results of a Survey
A survey of post-shorting construction loads on floors of multi-storey buildings is described. The estimated parameters of a probabilistic model of the peak (transient) loads are reported....
Floor Live Load Models and Pattern Load Effects
Probabilistic models of sustained live loads and equivalent uniformly distributed loads are discussed with regard to pattern load effects. A simple equivalent pattern load is identified...
The Evolution of an Environmental Monitor
After more than 40 years of planning, litigation, design and construction, one of the nation's most controversial highway projects is finished. The completion earlier this...
Upgrading Today's Terminals for Tomorrow's Needs
This paper describes how a 1940's vintage, timber pile supported wharf is being modernized to serve post-Panamax ships: how the Massachusetts Port Authority (MASSPORT) is rebuilding their...
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....
Nonprestressed and Prestressed FRP Sheets as External Reinforcement of Wood Members
The paper presents a summary of an analytical and experimental investigation of a new form of wood construction involving external bonding of thin fiber reinforced plastic (FRP) sheets...
Structural Performance of Hardwood-Metal Composite Beams
This research examines the deflection characteristics of layered timber/steel composite beams with hopes of applying such principles to large timber structures such as highway bridges....
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...
Mining for Building Expansion
Engineers adapted mining techniques to tunnel under a vibration sensitive manufacturing operation to create new working space below. IBM workers needed more working space at their Vermont...
Snow Fence Operational and Material Testing
The proliferation of snow fence products since the late 1970's presents an opportunity for optimizing the control of drifting snow. It also presents a challenge in discriminating...
The Growing Meet Market
The Delaware cities of Dover and Wilmington are only 5 mi apart. Their combined populations barely exceed 100,000. Yet each city is planning to build a new convention center to corner...
COFDEX: Composite Floor Design Expert
A knowledge-based system, called COFDEX, is presented for integrated minimum cost or minimum weight design of composite floors in multistory buildings. Developed in the expert system programming...
Computational Damage Modeling for Timber Reliability Analysis
Damage models for creep-rupture are used in conjunction with stochastic load models to evaluate lifetime failure probabilities of timber members and systems. This paper examines damage...
Hugo's Sturctural Damage in Puerto Rico
The results of a study of the wind damages caused by Hurricane Hugo is presented. Cases involving wood structures, industrial steel buildings, multistory reinforced concrete buildings,...
Are Timber Seawalls that Fail, Cost Effective??Seacliff State Beach Santa Cruz County, California
Proposed reconstruction of a major portion of a 5,100-foot long timber seawall at Seacliff State Beach in Santa Cruz County, California, in 1984, became a major controversy because of...
The Application of a Geographical Information System to Resource Management?The UK Offshore Sand and Gravel Case
In the United Kingdom coastal and offshore environments, the extraction of sand and gravel from the seabed requires a high level of professional management, because of the varied and often...
Destruction Caused by Hurricane Hugo: A Timber Resources Damage Assessment in a Coastal Region
Damage assessments of large areas impacted by intense natural storms can be difficult. The purpose of this paper is to investigate the area and amount of damage to pine forests within...
The Use of Aragonite as an Alternate Source of Beach Fill in Southeast Florida
The first full-scale use in the United States of imported aragonite sand for beach restoration was initiated at Fisher Island, Florida, in December, 1990. The project involved placement...
Innovative Reregulation Weirs for Dam Releases
Two different reregulation weir designs for dam release improvement are discussed. A porous timber crib is favored for applications where increased minimum flow is needed, and a labyrinth...
