Identifying the Critical Path and Building Coalitions for Restoring Degraded Areas of the Great Lakes
Since 1985, eight Great Lakes States, the Province of Ontario, and the governments of Canada and the United States have led the development and implementation of remedial action plans...
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....
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...
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...
Shipwreck Management in Michigan's Great Lakes
From the year 1679, when Sier de la Salle's legendary trading ship, the Griffin set sail and disappeared on its maiden voyage, to 1975 when the Edmund Fitzgerald went down...
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...
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...
Large Woody Debris Effects on Channel Friction Factor
A simple method for quantifying large woody debris (LWD) density and computing associated friction factors was developed and tested using data from the South Fork Obion River in western...
Safety Analysis of Handset Wood Slab Formworks
A reliability index is calculated for flexural strength of a handset wood slab formwork system. Load and resistance models are based on a survey of construction loads and wood test data...
Limit States Design of Wooden Formwork for Concrete Walls
Load and resistance factors are developed for ultimate limit states design of wooden formwork components for concrete walls when the lateral concrete pressures are computed using the ACI...
Dissolved Oxygen and Woody Debris: Detecting Sensitive Forest Streams
Early watershed studies showed that timber harvesting and yarding could depress dissolved oxygen in nearby streams when fresh slash entered streams and streamside shade was reduced. State...
Caring for a Covered Bridge
Today the quaint Cornish-Windsor covered bridge (winner of this year's Outstanding Civil Engineering Merit Award) doesn't look much different than it did when...
The U.K. Marina Industry?An Overview
This paper is written from the point of view of an established marina developer and operator and, as the title suggests, it purports to be nothing more than an overview of a number of...
Pressure-Treated Wood Effect on Marina Environment
Pressure treated Southern Pine and Douglas Fir are the most commonly used materials for marina construction in the United States. The preservatives currently used, creosote, chromated...
Guideline for Structural Condition Assessment of Existing Buildings
Changing economic conditions, concerns for historic preservation, emphasis on fully utilizing conveniently located structures, space shortages, and increasing cost of materials and products...
Historic Dam Rehab: Handle with Care
A growing number of dams across the U.S. are aging and in need of rehabilitation, but can they be brought up to current codes without compromising their historic integrity? Improved methods...
Practical Aspects of Structural Control
