Summary
The demands of the global economy require manufacturers to produce highly reliable and easily maintainable engineering products. Recent studies indicate that for many large and sophisticated products or systems, maintenance, and support account for as much as 60 to 75 percent of their life cycle costs. Therefore, the role of maintainability, maintenance, and reliability has become increasingly significant. Satisfying the pressing need for a volume that addresses these subjects with an interdiscilinary approach, Maintainability, Maintenance, and Reliability for Engineers distills knowledge specific to each discipline into one comprehensive resource.
After reviewing the history of all three fields and their interrelationships, the book covers mathematical concepts such as Boolean algebra laws, probability properties, mathematical definitions, and probability distributions. It includes reliability evaluation methods such as fault tree analysis, network reduction method, delta-method, Markov method, supplementary variables method, and reliabitity management, both mechanical and human. Highlihting maintainibility tools and functions, the author discusses topics in maintainibility management and costing including tasks during product life cycle, program plan, organization functions, design reviews, life cycle costing, investment cost elements, and life cycle cost estimation models. The author also includes coverage of maintenance engineering, focusing on safety, quality, corrective, and preventive maintenance. The book concludes with coverage of maintenance management costing and human errror in engineering maintenance and contains 60 illustrations, 16 tables, and more than 200 equations.
There is a definite need to considermaintainibility, maintenance, and reliability during product/system design and other phases. To achieve this goal effectively, it is absoulutely imperative to have a certain degree of understanding of each of these disciplines. Although many books cover one or two of these topics, this is the first to cover all three in a manner useful to engineering professionals.

This European Standard specifies the properties of aggregates and filler aggregates obtained by processing natural
or manufactured or recycled materials for use in bituminous mixtures and surface treatments for roads, airfields and
other trafficked areas. This standard does not cover the use of reclaimed bituminous mixtures.
It provides for the evaluation of conformity of the products to this European Standard.
NOTE 1 The requirements in this European Standard are based upon experience with aggregate types with an established
pattern of use. Care should be taken when considering the use of aggregates from sources with no such pattern of use, e.g.,
recycled aggregates and aggregates arising from certain industrial by-products. Such aggregates, which should comply with all
the requirements of this European Standard, could have other characteristics not included in Mandate M 125 that do not apply
to the generality of aggregates types with an established pattern of use and when required, provisions valid at the place of use
can be used to assess their suitability.
NOTE 2 Properties for lightweight aggregates are specified in prEN 13055-2.

GENERAL INTRODUCTION
Structural design is a systematic and iterative process that involves:
1) Identification of intended use and occupancy of a structure – by owner
2) Development of architectural plans and layout – by architect
3) Identification of structural framework – by engineer
4) Estimation of structural loads depending on use and occupancy
5) Analysis of the structure to determine member and connection design forces
6) Design of structural members and connections
7) Verification of design
8) Fabrication & Erection – by steel fabricator and contractor
9) Inspection and Approval – by state building official
Ideally, the owner and the architect, the architect and the engineer, and the engineer and the
fabricator/contractor will collaborate and interact on a regular basis to conceive, develop, design,
and build the structure in an efficient manner. The primary responsibilities of all these players
are as follows:
• Owner - primary responsibility is deciding the use and occupancy, and approving the
architectural plans of the building.
• Architect - primary responsibility is ensuring that the architectural plan of the building
interior is appropriate for the intended use and the overall building is aesthetically pleasing.
• Engineer – primary responsibility is ensuring the safety and serviceability of the structure,
i.e., designing the building to carry the loads safely and ___________.
• Fabricator – primary responsibility is ensuring that the designed members and connections
are fabricated economically in the shop or field as required.

Seismic Design And Evaluation Of Multistory Buildings Using Yield Point Spectra
Author: Edgar F. Black, Mark Aschheim | Size: 5.73 MB | Format:PDF | Publisher: University of Illinois at Urbana-Champaign | Year: 2000 | pages: 222
Seismic Design And Evaluation Of Multistory Buildings Using Yield Point Spectra
Constant ductility response spectra are presented for 15 recorded earthquakes ground
motions using the Yield Point Spectra (YPS) representation. Yield Point Spectra are used for
analysis and design of SDOF structures. The spectra were computed for bilinear and stiffness
degrading load-deformation models, for displacement ductilities equal to 1, 2, 4 and 8.
A methodology for the performance-based seismic design of regular multistory
buildings using Yield Point Spectra is described. The methodology is formulated to make use
of current code approaches as much as possible while allowing the design engineer to limit
the peak displacement response and, to some extent, the peak interstory drift to user-specified
values. To achieve this objective, the design methodology makes use of an equivalent SDOF
model of the building.
A method to estimate peak displacement response and interstory drift indices of
multistory buildings using YPS and establish SDOF formulations is also presented. The
method may be considered a new nonlinear static procedure (NSP). Interstory drift indices
(IDIs) are estimated using deformed shapes of the building based on the first mode shape and
combinations of the first and second mode shapes.
