Prediction of Debris Flow Prone Areas and Damage
It is very important when drawing hazard maps to estimate damage to houses from debris flow of certain fixed quantities. A debris flow disaster, which occurred in Kake Town, Hiroshima...
GIS: Easing Infrastructure Management
GIS provides an ideal means for city planners and engineers to plan construction and maintenance of water-distribution networks, wastewater-collection systems and treatment plants, highways,...
Design and Construction of Soil-Cement Drop Structures
Soil-cement has been used as an effective and economical slope protection material for embankment dams and stream banks. This paper describes the use of soil-cement in the construction...
CCM Overtopping Protection on Three Parkway Dams
Cellular concrete mat (CCM) overtopping protection systems have been designed for and will be installed on three small embankment dams along the Blue Ridge Parkway. Based on recent field...
Diversion Closure Gate Schemes Used on B.C. Hydro Dams
Over the last 25 years B.C. Hydro has designed, built and has operated a number of large dams and continues to do so. This paper describes the design, erection and operating experiences...
Landfill Liner Quality
Landfill liners are being made with new synthetic materials, materials which may be beyond the knowledge of the engineer in charge of the landfill construction project. Engineers need...
A Tale of Two Laboratories
Two unusual research centers are built with the materials that will be studied in them, but the similarities end there. GE Plastics' $10 million Living Environments concept...
Experimental Research and Parameters Optimization of a Prototype OWC Wave Power Device
The paper presents the experimental research and parameters optimization of a prototype oscillating water column (OWC) wave power device being built in China by Guangzhou Institute of...
U.S. Construction Aggregates
Crushed stone and sand and gravel are the two main sources of natural construction aggregates in the United States as well as in the world. At the beginning of the 20th century, the production...
Asphalt in the U.S. Transportation Infrastructure
Asphalt has been the major pavement material responsible for development of the transportation infrastructure enjoyed by American citizens. This paper addresses issues to be monitored...
The Future of Steel Structures
The future availability of steel as a construction material is covered in this paper. The advances in the material, design fabrication and erection are discussed. The quality and quantity...
Structural Wood Products
This paper provides a description of available structural wood products. Traditional products such as lumber and plywood are being supplemented by new products that include composite lumber...
Reliability Assessment of Wood Components
Considerable progress has been made in the nondestructive evaluation (NDE) of wood components since the introduction of the first concepts more than twenty-five years ago. New stress wave...
Wood Variability Effects in Structural Assessment
Engineers evaluating the load carrying capacities of in-service wood structures commonly determine the strength and stiffness properties of structural wood members by various assessment...
Effects of Physicochemical Factors on Asphalt Aging
A new model for asphalt oxidative aging is presented. The model proposes that the kinetics of low temperature aging in the pavement temperature range is largely governed by physicochemical...
Asphalt Age Hardening?Trends and Predictions
Pavement cracking is substantially related to the consistency of asphalt cement binders. The variation in hardness of binders is related primarily to asphalt characteristics, environment...
Recognition and Avoidance of Details That Adversely Affect the Performance of Exposed Wood Members
Factors that affect the deterioration of wood in structures are reviewed. Important points regarding wood-moisture relationships are noted. The requirements for decay of wood by fungi...
Protection of Wood Designs in Adverse Environments
Engineers and architects are becoming increasingly aware of the risks of poor wood design practices and the benefits of using wood properly. This paper addresses biological factors that...
