This book was developed while teaching a graduate course at several universities in the United States. Europe and Israel. during the last two decades. The purpose of the book is to introduce the fundamentals and applications of optimum structural design. Much work has been done in this area recently and many studies have been published. The book is an attempt to collect together selected topics of this literature and to present them in a unified approach. It meets the need for an introductory text covering the basic concepts of modem structural optimization. A previous book by the author on this subject ("Optimum Structural Design". published by McGraw-Hill New York in 1981 and by Maruzen Tokyo in 1983). has been used extensively as a text in many universities throughout the world. The present book reflects the rapid progress and recent developments in this area. A major difficulty in studying structural optimization is that integration of concepts used in several areas. such as structural analysis. numerical optimization and engineering design. is necessary in order to solve a specific problem. To facilitate the study of these topics. the book discusses in detail alternative problem formulations. the fundamentals of different optimization methods and various considerations related to structural design. The advantages and the limitations of the presented approaches are illustrated by numerous examples.

ViewCompanion Premiumยฎ is the most powerful member of the ViewCompanion family. ViewCompanion Premium can view, print and convert PLT plot files, Adobe PDF, Autodesk DWF, Postscript, CGM, TIFF, CALS and many other formats. ViewCompanion Premium support PLT plotter files using HPGL, HPGL/2, HP-RTL and Calcomp formats.
If you need to distribute drawings, e.g. on the Internet, you can convert your drawings to Autodesk Drawing Web Format (DWF), Scalable Vector Graphics (SVG) or Adobe PDF. All these formats are very popular for distributing drawings.
You can convert multiple files of different formats to a single multi-page PDF, DWF or TIFF file.
ViewCompanion can split a multi-page PDF, PDF or DWF files into several single paged files.
Your PLT, PDF, CGM and DWF files can be converted to Autodesk DXF format, which can be read by almost all CAD application, e.g.: Autodesk AutoCAD and Microstation.
Both batch conversion and printing is included. The software can be configured to monitor a user selected folder, and all files copied to that folder will be automatically printed.
ViewCompanion gives you advanced functions for zooming and panning, and you can view your files fast and accurate.
Use Viewcompanion's precise tools to measure dimension lengths and areas. You can measure using snap to drawing geometry for highest accuracy. Calibration of the measurement tools is available to make sure you get correct results if your drawings are not 1:1. The measurement results may be exported to csv, which can be loaded into Excel or any other spreadsheet application.
With ViewCompanion Premium you can add markups to the loaded file. Supported markup elements include rectangles, lines, dimension lines, area measurements, ellipses, polygons, text, arrows, stamps and images.
You can select one of the predefined stamps or create your own. User defined symbol libraries makes it easy to add frequently used symbols as markups. Hyperlinks can be added to markup elements, and a hyperlink can either open another drawing inside ViewCompanion, or open an Internet location (URL) using the default browser.
All markup elements are stored in a separate file and the original file will be left unmodified.
The markup elements can optionally be included when the viewed file is printed or converted.
You can export markup elements as Autodesk DXF, Autodesk DWF, CGM and other formats.

To date, the focus in the field of sustainable building has been on new building design. However, existing residential buildings inflict great environmental burden through three causes: continuous energy consumption, regular building maintenance and replacements. This publication analyses and compares these three causes of environmental burden and shows that material resources needed for replacements generally have a limited potential to reduce environmental impact. Reducing energy consumption for climate control and electrical appliances is much more effective. According to the author, sustainable measures should be tested for shifts in the kind of environmental impact caused due to the use of alternative types of energy resources and altered material quantities. The sustainability of the electricity supply is essential to decrease the total environmental impact of the residential building stock.

Author(s)/Editor(s): Hi Sun Choi, Goman Ho, Leonard Joseph & Neville Mathias | Size: 42 MB | Format:PDF | Quality:Scanner (bw) | Publisher: CTBUH | Year: 2012 | pages: 89 | ISBN: 9780939493340
An output of the CTBUH Outrigger Working Group, this guide sets out a comprehensive overview of the use of outriggers in skyscrapers. This guide offers detailed recommendations for analysis of outriggers within the lateral load resisting systems of tall buildings, for recognizing and addressing effects on building behavior and for practical design solutions. It also highlights concerns specific to the outrigger structural system such as differential column shortening and construction sequence impacts. Several project examples are explored in depth, illustrating the role of outrigger systems in tall building designs and providing ideas for future projects.
