  Steel Building Design: Medium Rise Braced Frames
Posted by: ir_71 - 03-24-2011, 06:54 AM - Forum: Steel - Replies (2)

Steel Building Design: Medium Rise Braced Frames

Author: D G BROWN, D C ILES, E YANDZIO | Size: 3.9 MB | Format: PDF | Publisher: SCI | Year: 2009 | pages: 127 | ISBN: 9781859421819

[Image: 16397985851563125418.jpg]


[Image: info.png]

This publication covers the design of braced steel-framed medium rise buildings, offers guidance on the structural design of the superstructure and gives general advice on such issues as foundations, building layout, service integration and construction programme. It is an updated version of the SCI publication Design of multi-storey braced frames (P334), which included both general design guidance and advice on detailed design to BS 5950. This publication refers to the Eurocodes, which are due to replace BS 5950. An overview is given of the common floor systems used in multi-storey structures, providing typical framing layouts, typical member sizes and construction depths. Detailed guidance is given on the design of the bracing system in accordance with Eurocode 3, with particular attention to allowance for second order effects. Guidance is also given on the application of the ‘robustness rules’ in Eurocode 1 (Part 1-7, Accidental actions), which are intended to ensure adequate tying resistance and the avoidance of disproportionate collapse.

  Natural Wastewater Treatment Systems
Posted by: ir_71 - 03-24-2011, 06:16 AM - Forum: Water & Hydraulic Engineering - Replies (1)

Natural Wastewater Treatment Systems

Author: Ronald W. Crites, E. Joe Middlebrooks, Sherwood C. Reed | Size: 11.4 MB | Format: PDF | Publisher: CRC Press | Year: 2005 | pages: 576 | ISBN: 9780849338045

[Image: 10006071951002488224.jpg]

[Image: 52652013093520799685.jpeg]

[Image: info.png]

Features
Presents detailed coverage of all natural wastewater treatment systems Covers slow rate, overland flow, and soil aquifer treatment systems of land treatment and reuse
Discusses dewatering, disposal, conditioning, and reuse methods of sludge management Provides performance data on the removal of constituents such as nutrients, metals, pathogens, trace organics, and endocrine-disrupting chemicals
Includes a section on vertical flow wetlands not found in any other book, reflecting the exceptional performance from European and Canadian experience

Summary
Although initially based purely on environmental principles of reuse and recycling, natural waste treatment systems proved to have economic advantages over mechanical systems in many cases, being less expensive to build and operate as well as requiring less energy. Thus, natural waste treatment methods reemerged even as advanced wastewater treatment technologies exploded in growth. Reflecting this burgeoning popularity, Natural Wastewater Treatment Systems is the first book to integrate all the major types of natural treatment systems into a single source.

Beginning with an overview of the types of natural treatment systems, the book outlines the planning, feasibility assessment, and site selection processes unique to natural processes as well as the basic process responses and interactions governing natural systems. The authors then examine the systems in detail, discussing wastewater pond systems, free water surface constructed wetlands, subsurface and vertical flow constructed wetlands, land treatment, sludge management, and onsite wastewater systems. They illustrate the practical aspects through 30 examples; include 178 data tables for comparing costs, performance, and constraints; and describe new approaches to partially mixed ponds, including dual-powered aeration ponds.

Written by eminent experts in natural waste treatment, Natural Wastewater Treatment Systems is an invaluable tool for selecting, planning, and implementing ecologically and economically sound wastewater treatment systems.

  INSDAG: THE STRUCTURAL USE OF STEELWORK IN BUILDINGS
Posted by: ir_71 - 03-24-2011, 06:04 AM - Forum: Steel - Replies (2)

INSDAG GUIDE FOR THE STRUCTURAL USE OF STEELWORK IN BUILDINGS

Author: Dr. Rangachari Narayanan Dr. V. Kalyanraman | Size: 10.3 MB | Format: PDF | Publisher: INSDAG | Year: 2003 | pages: 198

[Image: 91782040146671375111.jpg]


[Image: info.png]

This Guide provides general recommendations for the design of structural steel work in buildings and allied structures. In the absence of an Indian Standard written in the modern Limit State Format for steel construction, this guide generally follows the provisions contained in British Standard, BS: 5950 (various parts). INSDAG has a Memorandum of Understanding with the British Steel Construction Institute and several supporting documents are available from INSDAG at largely discounted prices for the use of steel designers in India. It will not apply to bridges, chimneys, cranes, tanks, transmission line towers, storage structures, tubular structures, however, general .principles discussed in this guide could be adopted in the design of such structures appropriately. This guide is in three parts and covers the design of building structures using (i) Hot Rolled Steel section (ii) Cold Rolled Steel sections and (iii) Steel Concrete Composite sections. The guide provides only general advice regarding the various loads to be considered in design. For actual loads to be used reference may be made to IS: 875-1987. This document is NOT a statutory document and intended as a guide for students and practicing engineers. It is not intended to replace Codes of Practice.

  How Designers Think: The Design Process Demystified
Posted by: foxxx2010 - 03-23-2011, 05:38 PM - Forum: Architecture Books - No Replies

How Designers Think: The Design Process Demystified

[Image: 83645916481570940994.jpg]


[Image: info.png]
How Designers Think is based on Bryan Lawson's many observations of designers at work, interviews with designers and their clients and collaborators. This extended work is the culmination of forty years' research and shows the belief that we all can, and do, design, and that we can learn to design better. The creative mind continues to have the power to surprise and this book aims to nurture and extend this creativity. Neither the earlier editions, nor this book, are intended as authoritative prescriptions of how designers should think but provide helpful advice on how to develop an understanding of design.

In this fourth edition, Bryan Lawson continues to try and understand how designers think, to explore how they might be better educated and to develop techniques to assist them in their task. Some chapters have been revised and three completely new chapters added. The book is now intended to be read in conjunction with What Designers Know which is a companion volume. Some of the ideas previously discussed in the third edition of How Designers Think are now explored more thoroughly in What Designers Know. For the first time this fourth edition works towards a model of designing and the skills that collectively constitute the design process.

* A unique look at the psychology of the designer that provides a greater insight to the process of design
* 'Demystifies' the complexity of the subject and uncovers new ways that design can be done
* Conclusions are drawn from years of research and provide the very latest debate on the subject

  Fracture Mechanics: An Introduction
Posted by: cace-01 - 03-23-2011, 02:58 PM - Forum: Mechanics & Material Technology (Elasticity, Plasticity and Nonlinearity) - Replies (4)

Fracture Mechanics: An Introduction

Author: Gdoutos E E | Size: ~8.5 MB | Format: PDF | Publisher: Springer | Year: 1993 | pages: 328 | ISBN: 079231932X

[Image: 12278317898512163214.jpeg]


[Image: info.png]
New developments in the applications of fracture mechanics to engineering problems have taken place in the last years. Composite materials have extensively been used in engineering problems. Quasi-brittle materials including concrete, cement pastes, rock, soil, etc. all benefit from these developments. Layered materials and especially thin film/substrate systems are becoming important in small volume systems used in micro and nanoelectromechancial systems (MEMS and NEMS). Nanostructured materials are being introduced in our every day life. In all these problems fracture mechanics plays a major role for the prediction of failure and safe design of materials and structures. These new challenges motivated the author to proceed with the second edition of the book.
