Landslide Hazard Rating for the Oregon Coast Range
The landslide hazard rating system for shallow soils on steep terrain over hard sandstone has three components: ground water response to precipitation, soil shear strength (including root...

Embankment Foundation Densification by Compaction Grouting
Compaction grouting is an attractive alternate for in-place densification of liquefiable soils below existing structures. Compaction grouting application concepts and procedures are presented...

Acoustic Emission Monitoring of Grout Movement
This paper describes the acoustic emission (AE) method in general, and in particular the AE system which holds significant promise in this regard. Used was a multichannel AE system which...

Grout Slurries?Thick or Thin?
In this paper some recent experiences in dam grouting in several countries are discussed where bentonite or Intraplast additives were used to control sedimentation, viscosity, grout density,...

Nonlinear Fracture Process Zone in Rock
A study of the fracture process zone was conducted to gain an understanding of the physics of crack propagation in rock. The nondestructive testing technique of acoustic emissions was...

Oil Shale Fracture Characterization by a New Model
Fracture toughness of oil shale is a property which is essential for fracture characterization needed for energy resource development and recovery. However, a data base for fracture toughness...

Load-Carrying Capacity and Remaining Life of First-Built Composite Girder Bridge in Japan
Kanzaki Bridge, Osaka, Japan, was the first steel-concrete composite bridge built in 1953 to carry the Osaka Prefectural Road over Kanzaki River. The bridge was removed in 1978 after 25...

Design and Testing of a 400 Ft Span Plate Girder Bridge
The paper describes design features and testing of the Madawaska River Bridge. The bridge is unique in being the longest span plate girder bridge in Ontario, having continuous spans of...

Composite Steel Deck Bridge: An Experimental Study
Composite steel decks with steel fiber reinforced concrete (SFRC) were developed, aiming to improve the durability of the deck pavement and to increase the rigidity of the deck plate in...

Dynamic-Fatigue Response of Continuous Composite Bridges
The dynamic response of continuous composite bridges and the influence of fatigue loading at resonance frequency on the structural response are investigated. It is shown that cracking...

Application of Preflexed Composite Beams to Continuous Bridges
A preflexed beam is a type of concrete encased steel beam of which prestressing has been introduced in the lower flange concrete. Recently, the preflexed composite beams were applied to...

The Eurocodes and Shrinkage in Composite Beams
The two parts of this paper relate to different aspects of design procedures for composite structures of steel and concrete. First, recent developments in the coordination of the eight...

Beam-to-Column Connection of a Composite Structure
Composite structures can exhibit excellent performance against seismic force, and fire safety as well. However, the traditional steel reinforced concrete (SRC) system or concrete encased...

Beam to Column Stress Transfer in Composite Structures
To clarify the mechanism of the stress transfer from the steel beam to the composite column through the beam-column joint, eight exterior beam column assemblies were tested under reversed...

Seismic Capacity Evaluation of SRC Buildings
The Japanese standard for seismic capacity evaluation of existing composite steel and reinforced concrete (SRC) buildings was introduced. As it developed, based on the previously established...

Seismic Strengthening of Existing RC Buildings
Seismic strengthening of existing reinforced concrete (RC) frame buildings by the use of steel braces or panels was studied experimentally. A special joint between steel elements and the...

Construction QA/QC Systems that Work
Case Studies
Four case studies discuss the issue of responsibility for quality assurance and quality control by describing actual situations where quality work is being done in the field. The case...

Geographic Information Systems: A Planning Tool
Geographic Information Systems provide an opportunity for water resource planners to examine potential impacts of proposed plans early in the study process. Conflicts can be identified...

Analysis of Reservoir Operations on the IBM-PC
The optimization of reservoir operations is a major economic concern. This paper contributes a computer software package, SPORO, written for the IBM-PC, for the stochastic optimization...

Forecasting Demand for Urban Water
The purpose of this study is to assess current water use forecasting practice in the US Army Corps of Engineers and to recommend additional approaches which best satisfy current requirements....
