Wang's Equation for Ice Forces From a Pressure Ridge
Yung-shih (Tony) Wang has presented an equation for the breaking loads from a multiyear pressure ridge on a conical structure. The three distances that define the position of the plastic...
Snow Transport as a Function of Wind Speed and Height
When limitations are placed on mass flux in the saltation layer, a regression equation relating mass flux to wind speed and height above surface, developed by Mellor and Fellers (1986),...
Recommended Cold Regions Meteorological Instrumentation
For nearly 30 years, CRREL has studied environmental conditions in winter weather. These efforts have concentrated on providing field-measured meteorological data and historical climatological...
Structural Renovation of Tall Chimneys
This paper describes several tall chimney projects where major renovations were performed to the linings which required complete structural analysis of the existing chimney and foundation....
Modeling in Support of Hanford Site Waste Management
The waste management practices for both radioactive and hazardous wastes at the Hanford Site are designed to comply with all applicable state and federal regulations. Results from numerical...
Procedure for Seismic Evaluation and Design of Small Bore Piping
Simplified methods for the seismic design for small bore piping in nuclear power plants have been used for many years. Various pipe designers have developed unique methods to treat the...
Optimization Models for Acid Rain Control
A series of related optimization formulations are presented for developing and analyzing acid rain control strategies. These models span a wide array of approaches and reflect a similarly...
Introduction to Structural and Mechanical Failure Modes for Nuclear Power Facilities
The three papers presented in this section discuss the types of information (i.e., dynamic tests, earthquake experience and analytical data) which are used in predicting the capacity of...
Containment Capacity and Failure Modes Beyond Design Basis Conditions
Analytical and experimental studies have shown that containments can at least sustain two to three times design pressures. Under the severe accident overpressure loading, experimental...
Low-Rise Shear Wall Failure Modes
A summary of the data that are available concerning the structural response of low-rise shear walls is presented. These data will be used to address two failure modes associated with shear...
Failure Modes of Flat Bottom Vertical Storage Tanks
Flat bottom vertical storage tanks are important components in essential nuclear power plant safety systems. Data on the seismic capacity and failure modes of such tanks have been identified,...
A Computerized Completion
The original designers of the 1.6 million sq ft Fillmore Center in San Francisco (its largest mixed-use development project in 20 years) had specified a large amount of steel reinforcement...
The Human Factor in Failures
Human shortcomings cause three-quarters of project failures. A study of 500 case histories led to this assumption. One such failure at the Walter Bouldin dam in Alabama, is described in...
Beyond Engineering: The Politics of Maracaibo
The Lake Maracaibo Bridge in Venezuela was built in 1959. It ranks as one of the largest and longest bridges in the world at the time it was built and contained the longest concrete cable-stayed...
Approximate Methods of Structural Analysis: Principles and Pitfalls
In this modern age when the trend in structural engineering and structural engineering education is to make more and more use of computers and standard structural analysis programs, there...
Structural Approximations in Multi-Story Buildings
Simplified computer analyses and various approximate hand calculation methods are extremely valuable in structural engineering for multi-story buildings both during the preliminary design...
Wind Frame Design for Mid Rise Buildings
A brief discussion of drift limits is followed by design procedures for unbraced moment resisting wind frames and initial selection of optimized member sizes for chevron bracing frames....
Simplified Second-Order Inelastic Analysis for Steel Frame Design
Several current approaches are outlined that account for the spreading of plasticity in a second-order inelastic analysis of frames. The approaches are based on modifications to the simple...
The Boundary Element Method in Engineering Practice
The boundary element method (BEM) provides an excellent basis for the development of integrated design and analysis systems. The technique possesses the advantages of simple model generation,...
Verification of Advanced Analysis Techniques
As a designer there is a concern over the complexity of analysis required by design specifications and building codes because it forces engineers into types of analysis for which many...
