This paper provides the theoretical background of a simplified seismic design procedure for cylindrical ground-supported tanks. The procedure takes into account impulsive and convective (sloshing) actions of the liquid in flexible steel or concrete tanks fixed to rigid foundations. Seismic responses – base shear, overturning moment, and sloshing wave height – are calculated by using the site response spectra and performing a few simple calculations. An example is presented to illustrate the procedure, and a comparison is made with the detailed modal analysis procedure. The simplified procedure has been adopted in Eurocode 8.

This paper presents the formulation and implementation of a new static push-over analysis algorithm for the seismic rehabilitation of building frames, in accordance with “NEHRP Guidelines for the Seismic Rehabilitation of Buildings”. The concept of the push-over analysis is described and problems associatedwith its implementation in a nonlinear finite element program are examined. Earlier work, which contributed to the development of the strategy, is reviewed. The theory of the solution algorithm is presented with special consideration placed on the stability of the algorithm and the method of iteration for the nonlinear behavior.
Examples are carried out that demonstrate the remarkably stable and efficient procedure.

Life Cycle Costing for Engineers

Cradle-to-grave analyses are becoming the norm, as an increasing amount of corporations and government agencies are basing their procurement decisions not only on initial costs but also on life cycle costs. And while life cycle costing has been covered in journals and conference proceedings, few, if any, books have gathered this information into an easily accessible resource. Eliminating the need to consult many different sources, Life Cycle Costing for Engineers brings together up-to-date life cycle costing concepts and explains their application in various industrial sectors.

The author sets the scene with a chapter on fundamental economics followed by a chapter on reliability and maintainability, providing background information and platform for further understanding. He then discusses life cycle costing fundamentals, models and estimation methods, reliability, quality, safety, and manufacturing costing, and maintenance, maintainability, usability, and warranty costing. The book includes life cycle costing for computer systems and software, transportation systems, aircraft turbine engines, cargo ships, rail systems, civil engineering structures, and energy systems. An in-depth look at cost estimation models and engineering reliability and maintainability topics such as bathtub hazard rate curve, common reliability networks, general reliability, mean time to failure, and hazard rate formulas round out the coverage.

Filled with examples, tables, figures, and equations, this book integrates life cycle costing concepts for use in industrial and other sectors. It provides a modern treatment of the subject that can easily be applied to any industry.
