Damage Model for Buildings Subjected to Earthquakes
A model based on random vibration method is developed for assessing building damage to earthquakes. The damage of reinforced concrete structures is expressed as a linear combination of...
Seismic Analysis of Horse Creek Dam, Hudson, Colorado
On April 8, 1981, six days after a Richter magnitude 4. 0 earthquake, inspectors from the Colorado State Engineer's Office discovered a small crack in outboard side of Horse...
Aesthetics and Design of Prestressed High-Rise Buildings
This paper will address the aesthetics, economic and construction-related advantages of prestressed concrete for high-rise buildings, with an emphasis on the South-East Asia region. While...
Filters and Leakage Control in Embankment Dams
In the practice of earth dam engineering there has been some doubt that downstream filters could be relied upon completely to control and seal concentrated leaks through impervious dam...
Embankment Seepage Control Design and Construction
For seepage control features of embankment dams, design criteria and construction practice is reviewed as it is reflected in the experience of the U. S. Army Corps of Engineers. The generally...
Abutment Seepage at Smithville Dam
After initial filling there was concern for the stability of Smithville Dam when higher than anticipated piezometric levels were experienced in the left abutment foundation. Concern heightened...
Seepage Control at Cochiti Dam, New Mexico
Significant design data, design assumptions and computations, and performance of the seepage control features provided at Cochiti Dam are summarized in this paper. The dam is a rolled...
Hydraulic Fracturing in Embankment Dams
There is now sufficient evidence to conclude that concentrated leaks occur commonly through the impervious sections of embankment dams by hydraulic fracturing without being observed, even...
Soldier Creek Dam Foundation Drainage
A possible mode of failure for Teton Dam, piping of erodible core material through unsealed foundation joints, was also concluded as being possible at Soldier Creek Dam, Utah. Evaluations...
The Use and Performance of Seepage Reduction Measures
The utilization and performance of various foundation seepage reduction measures from over 100 dams situated on pervious soils throughout the world has been reviewed. Summary discussions...
Designing and Monitoring for Seepage at Calamus Dam
Given the complex, pervious nature of the foundation for Calamus Dam, every effort has been made to incorporate design features that will reduce and control the anticipated large volumes...
Seepage Control for Embankment Dams USBR Practice
The current Bureau of Reclamation approach to seepage assessment, analysis, and design for embankment dams is described. The advantages and appropriate applications for the analysis programs...
Use of Asphalt in Treatment of Dam Foundation Leakage, Stewartsville Dam
This paper presents the recent development and application of a hot asphalt grouting technique used to stop a 5,000 Imperial Gallons Per Minute (IGPM) (22,000 lpm) dam leakage under full...
Chemical Grout Curtains at Ox Mountain Dams
Grout curtains were constructed in granodiorite bedrock as part of two earthfill diversion dams at a sanitary landfill site on the San Francisco, California peninsula. The curtains are...
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...
Computer Applications in Grouting
The first use of computers during foundation grouting was tried by the Bureau of Reclamation on Ridgeway Dam in Colorado. It was very useful in monitoring real time down hole conditions...
Computer-Assisted Grouting Evaluation Systems
Electronic monitoring of cement pressure grouting at Ridgway Dam provides a powerful tool for geologic assessment of drilling and grouting results. Graphic surveillance and analysis of...
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,...
Proposed Design Criteria for Composite Steel Deck Slabs
Composite steel deck slabs have continued to gain popularity; today they are one of the predominant means of floor slab construction in most typical buildings. The term 'composite...
Strength of Composite Beams under Seismic Loading
Effective width of a concrete slab of a composite beam is specified in various specifications, but their theoretical backgrounds are obscure. Originally, they must have been specified...
