  A New Approach for Design of Steel Beam-Columns
Posted by: preceptor - 12-02-2009, 08:35 PM - Forum: Journals, Papers and Presentations - Replies (1)

A New Approach for Design of Steel Beam-Columns

[Image: 98681636508241297597.jpg]

[Image: info.png]
ABSTRACT
Design aids are developed using the AISC-LRFD Specifications for design of steel beam-columns. These aids give designers more options in design and often allow selection of sections that are more efficient for a given set of conditions than the current design aids do. Several examples are worked out using the current method of practice as well as the proposed method developed in this paper.

Stress Ribbon and Cable-Supported Pedestrian Bridges
By Jiri Strasky


* Publisher: Thomas Telford Ltd
* Number Of Pages: 240

* ISBN-13 / EAN: 9780727732828

'Stress-ribbon bridges' is the term used to describe structures formed by a very slender concrete deck in the shape of a catenary. They can be designed with one or more spans and are characterized by successive and complementary smooth curves. These curves blend into the natural environment and their forms, the most simple and basic of structural solutions, clearly articulate the flow of internal forces which can be erected without undue pressure on the environment. "Stress Ribbon and Cable-supported Pedestrian Bridges" looks at how slender concrete decks are used in the design of suspension and cable stayed structures.It looks at their characteristic feature; their rigidity, which is mainly given by the tension stiffness of prestressed concrete decking, so much so that movement caused by pedestrians or wind does not register as discomfort by users. Starting with a brief history the title describes structural types, addresses general design criteria, current technology, static and dynamic analysis and discusses the results of the static and dynamic loading tests. Illustrated throughout, "Stress Ribbon and Cable-Supported Pedestrian Bridges" provides examples of outstanding structures, which have been recently completed. This book will be of value to practicing engineers who wish to understand the premises upon which the rules are based and researchers who wish to develop the subject further and students who wish to delve into the background behind the current loading rules.

Bridge Design for Economy and Durability: Concepts for New, Strengthened and Replacement Bridges
By Brian Pritchard


* Publisher: Thomas Telford
* Number Of Pages: 172
* Publication Date: 1992-11
* ISBN-10 / ASIN: 0727716719
* ISBN-13 / EAN: 9780727716712



Product Description:

This comprehensive book describes a number of new or updated bridging concepts which were developed and successfully applied during the author's forty years of close involvement with UK and international bridge design, construction, maintenance and research. The concepts mainly apply to the small/medium span range of bridges and viaducts and contribute to one or more of the following features: design and construction economy in both time and money; ease of inspection and minimum maintenance; ride quality and safety; good appearance; and strengthening when required with minimum traffic disruption.

  The 5 Golden Rules of Project Management
Posted by: rendel_© - 12-02-2009, 10:33 AM - Forum: Free Discussion - No Replies

The 5 Golden Rules of Project Management

Rule 1: Time Management is Critical

To deliver your project on time, you need to manage time carefully. To do this, make sure every task is listed in a Project Plan and that they are scheduled to occur precisely when they need to.

Every week, update your plan with the time spent completing tasks and identify whether each task is ahead or behind schedule. Track the % complete of each task and if it's behind schedule, then get it back on track by assigning more resource or reducing the scope of the task. Don't let tasks slip. Be vigilant.

Rule 2: Track Costs and Manage Finances

Every element of your project incurs a cost. You need to identify all of the planned costs upfront and get them approved by your manager.

Then record every expense as it occurs - including people, equipment and materials. Check that your actual expenditure does not exceed your planned expenditure. And if it does, then you need to cut back. If you're running over budget, tell your Project Sponsor early.

Rule 3: Ensure Quality Targets are Set

You need to specify upfront exactly what it is that the project will deliver (i.e. the "deliverables" ). Then set targets for the quality of these deliverables. Get your quality targets agreed by your customer.

Then every week, review the quality of each deliverable produced by the project. If it's not up to standard, fix it immediately. Never wait until the end of the project before fixing up quality issues.

Rule 4: Control Scope at the Micro Level

Your scope is defined as "the set of deliverables that need to be produced by the project". So make sure that you know what your scope is, try not to let anyone change it.

Check every week that your team is working on "just" the set of deliverables agreed, and nothing more. Check that every deliverable being produced exactly matches the specification you've defined for it. Note: An increase in the scope of your project will make it harder to deliver.

Rule 5: Resolve Issues Early

If issues arise during the project, then resolve them early. Pounce on every issue before it delays your project. Record it formally and then track it until it's resolved. Unresolved issues lead to delays which lead to project failure. Stay safe – resolve issues early.

Applied Strength of Materials 4th
Robert L.Mott,
Prentice Hall | 2001 | ISBN : 0130885797 | PDF | 238 pages | 5.6 MB | RS.com

Applied Strength of Materials provides comprehensive coverage of the key topics in strength of materials with an emphasis on applications, problem solving, and design of structural members, mechanical devices, and systems. The fourth edition of this best-selling text has been updated and enhanced to include a new "Big Picture" feature and a brief review of statics in a new appendix. Strengths of this text include: bull; A section called The Big Picture begins each chapter and engages students in discussion of the many contexts in which the principles in that chapter are used in real, practical design. This feature draws on the students' own experience and builds their knowledge of the mechanical design field. It is based on the learning theory that students learn better when they can relate new concepts to past experiences and when they consider the whole before tackling the details. An extensive introduction to composite materials along with the commentary throughout the book on the application of composites to various kinds of load-carrying members and comparisons/contrasts of composites to traditional structural members. Suggested computer programming assignments with recommended uses for spreadsheets, equation-solving software such as MATLAB, and graphing calculators to reflect the continuing development of electronic aids. Strong presentation of design approaches in addition to analysis, providing extensive information on guidelines for design of mechanical devices and structural members.
