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...
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...
An Application of Probability to Rock Slope Design
This paper describes the use of probability and statistics in the slope design process. An example is presented of a high rock slope in an open pit mine. This slope is a major concern...
A Combined Limit Equilibrium and Statistical Analysis of Wedges for Design of High Rock Slopes
This paper describes a unique technique developed for the statistical analysis of wedge failures which control the design of high slopes in relatively hard jointed rock masses. Using this...
Probability Applied to Slope Design?Case Histories
A major problem encountered with the choice of an appropriate value for the design probability. Initial experience, obtained during open-pit investigation, suggested that slope geometry...
High Strength Steel
A
Critical Load Program
The elastic critical load of a structural frame is a fundamental parameter in assessing its stability. It is an upper bound to the failure load of the frame, in the same way that the Euler...
Detection of Leakage Through Subsurface Barriers Using Guided Acoustic Waves
The primary method for preventing hazardous liquid and leachates from entering the groundwater is the use of a physical barrier. These barriers are susceptible to a number of mechanisms...
Modeling Failure Probability of Underground Pipes
Factors influencing the performance of underground gas pipes are identified through a literature search and contacts with several utility companies. These factors are categorized as (i),...
Solving the Two-Dimensional Diffusion Flow Model
A simplification of the two-dimensional (2-D) continuity and momentum equations is the diffusion equation. To investigate its capability, the numerical model using the diffusion approach...
Toward User-Oriented Failure Management Strategies for the Morgantown People Mover
The Morgantown People Mover (MPM) is the most sophisticated automated people movers in the United States. It is the only one that offers 'personalized' service...
An In-Plane Finite Element Model for Brick Masonry
A finite element model for brick masonry is reported. The model takes account of non linear deformations and progressive local failure. The failure may occur in the joints alone or in...
Shear Design of Masonry Walls
The paper presents a summary of a research project carried out at the Swiss Federal Institute of Technology Zurich to develop a design method based on the ultimate strength of masonry...
Notes on Statistics of Failures of Constructed Works
This paper is concerned with both catastrophic and sub-catastrophic failures, which may be categorized into three types: Safety (type S), Functional (type F), and Ancillary (type A). Often...
Failure Statistics Categorized by Cause and Generic Class
Failures can be classified into the three categories, ie. , SAFETY, FUNCTIONAL, and ANCILLARY. Within the causation definition, failures fall into five general areas: DESIGN DEFICIENCIES;...
Failure Investigation Process
The purpose of this paper is to consider the present failure investigation process, in order to assess whether failures are being properly investigated, and also whether sufficient information...
Alternative Procedures for Investigating Failures
Failures of engineered structures continue to occur. This is despite rapid advances in engineering theory, new, more sophisticated methods of analysis, and streamlined techniques for preparing...
Information Availability
There seems to be a great deal of concern about lack of availability of information concerning the results of failure investigations. In most court cases there is virtually no technical...
Failure Information Needs in Civil Engineering
If we are to learn from failures of engineered facilities, failure information must be in a useful form, and it must reach those who can effect improved practice. This paper discusses,...
Learning from Failures
Modern technology and innovation have created a gap between what the design drawings predict with respect to safety and serviceability of a structure and the real safety and serviceability...
