Numerical Partial Differential Equations for Environmental Scientists and Engineers: A First Practical Course
Author(s): Daniel R. Lynch
Publisher: Springer
Date: 2004 Format: PDF Language: English
ISBN10: 0387236198
Pages: 392
This book concerns the practical solution of Partial Differential Equations (PDEs). It reflects an interdisciplinary approach to problems occurring in natural environmental media: the hydrosphere, atmosphere, cryosphere, lithosphere, biosphere and ionosphere. It assumes the reader has gained some intuitive knowledge of PDE solution properties and now wants to solve some for real, in the context of practical problems arising in real situations. The practical aspect of this book is the infused focus on computation. It presents two major discretization methods – Finite Difference and Finite Element. The blend of theory, analysis, and implementation practicality supports solving and understanding complicated problems. It is divided into three parts. Part I is an overview of Finite Difference Methods. Part II focuses on Finite Element Methods, including an FEM tutorial. Part III deals with Inverse Methods, introducing formal approaches to practical problems which are ill-posed.

Seismic Risk Assessment and Retrofitting - With Special Emphasis on Existing Low Rise Structures
by Alper Ilki (Editor), Faruk Karadogan (Editor), Sumru Pala (Editor), Ercan Yuksel (Editor)
Description:
Many more people are coming to live in earthquake-prone areas, especially urban ones. Many such areas contain low-rise, low-cost housing, while little money is available to retrofit the buildings to avoid total collapse and thus potentially save lives. The lack of money, especially in developing countries, is exacerbated by difficulties with administration, implementation and public awareness. The future of modern earthquake engineering will come to be dominated by new kinds of measuring technologies, new materials developed especially for low-rise, low-cost buildings, simpler and thus lower cost options for retrofitting, cost cutting and raising public awareness.
The book covers all the areas involved in this complex issue, from the prevention of total building collapse, through improvement techniques, to legal, financial, taxation and social issues.
The contributors have all made valuable contributions in their own particular fields; all of them are or have been closely involved with the issues that can arise in seismic zones in any country. The recent research results published here offer invaluable pointers to practicing engineers and administrators, as well as other scientists whose work involves saving the lives and property of the many millions of people who live and work in hazardous buildings.

code of practice for the use of
alternative steel materials in design
Screenshot:
(Image added by moderator)
PDF file - 89 pages
This design guide serves as Singapore’s national code of practice for the use of alternative steel materials in design to the British Standard “BS 5950 Structural use of steelwork in building”, including those manufactured to British Standards. Steel materials not covered in BS 5950 by default shall be allowed with or without restrictions if they are in compliance with the provisions of this design guide.
The objective of this design guide is to ensure that only adequate (in terms of material performance) and reliable (in terms of quality assurance) steel materials, regardless of material standards to which the materials are manufactured to, are used in the design of structural steelworks to ensure public safety.
This design guide only gives provisions for structural design based on BS 5950, and therefore only serves as guidance at the design stage. It has been assumed in the drafting of this design guide that the execution of its provisions is entrusted to appropriately qualified persons, in compliance with appropriate execution standards to control materials, fabrication and erection of steelwork.
As a code of practice, this design guide takes the form of guidance and recommendations. It should not be quoted as if it was a specification and particular care should be taken to ensure that claims of compliance are not misleading. Reference for additional design recommendations other than those given in this design guide shall be made to various parts of BS 5950.
This design guide does not purport to include all the necessary provisions of a contract. Users of this design guide are responsible for their correct application.
Compliance with this design guide does not of itself confer immunity from legal obligations.

Intermediate Dynamics for Engineers: A Unified Treatment of Newton-Euler and Lagrangian Mechanics
Intermediate Dynamics for Engineers: A Unified Treatment of Newton-Euler and Lagrangian Mechanics
By Oliver O'Reilly
Publisher: Cambridge University Press
Number Of Pages: 408
Publication Date: 2008-08-04
ISBN-10 / ASIN: 0521874831
ISBN-13 / EAN: 9780521874830
Binding: Hardcover
Product Description:
This book has sufficient material for two full-length semester courses in advanced engineering dynamics. As such it contains two tracks (which overlap in places). During the first course a Newton-Euler approach is used, followed by a Lagrangian approach in the second. In discussing rotations for the second course, time constraints permit a detailed discussion of only the Euler angle parameterization of a rotation tensor from Chapter 6 and a brief mention of the examples on rigid body dynamics discussed in Chapter 9. The text includes invaluable exercises at the end of each chapter that are highly structured and intended as a self-study aid. Validated solutions are provided, many of which can be performed in simulation using MATLAB® or Mathematica®.

As a engineer or manager many times we have to estimate quantities (bill of material) at early stage (feasibility stage) of project. This is required by client to get an idea of capital cost of project for budget purpose. Client needs this to present the bank to get the loan for a particular project. This estimate is also important for us as engineers to give some how (+/- 15% ) cost of our discipline. All these quantities are based on our previous projects or thumb rules. If these quantities are close enough to real, it makes our position stronger in market.
I would like to discuss these MTO (material take off) with all you guys, so we can share our experience and achieve better results in future. Any of you have similar kind (multistory commercial/residential) of information, please share it.
I will start with my numbers.
1) Enclsed or partially enclosed process building (mining sector with multiple floors 60.0 ft high)
Structural Steel = 1.2 to 1.5 lb/ft^3 (Vol. of Building in ft^3)
Structural Concrete= .07 to .09 Cu. yd/ft^2 (GF Covered Area ft^2) (individual footing or pile cap for each column)

Software used for the design, analysis and manufacture of pre-tensioned fabric structures.
Patterner for Windows ® - Bruno Postle
Patterner is one of the few software packages in the world to provide the tools to create membrane structures. Developed in house at Rudi Enos Design by Bruno Postle, it is considered to be 'state of the art' for visualisation and patterning. All the production patterns for many different projects have been created with 'Patterner'. See www.patterner.co.uk
Tech-net 'EASY' membrane force and cable analysis software.
EASY analysis tools provide the most effective method of assessing the forces in the structures membrane, it's cables and the reaction loads on the supporting steelwork. With the ability to define and model precisely the ultimate tensile strength and stiffness of the membrane and reinforcement materials, and then to determine maximum loads, deflections and reaction loads from the dynamic membrane, every condition can be simulated and shown.
Fabric structures possess significant structural and architectural advantages over conventional structures. However, fabric structures also present a unique set of design challenges. The shapes of membrane structures cannot be chosen at random. The absence of bending resistance's requires designers to work within the constraints of feasible membrane equilibrium shapes. These shapes are usually complex, doubly curved surfaces which must be pretensioned in such a way to resist applied loading such as wind and snow. A tensile membrane structure is prestressed and stabilised by the counteracting tensions of opposing curvatures of an anticlastic surface (two-directional curvature of opposite sign, as a saddle surface). Where flat profile sheet design is envisaged, the initial prestress is significantly higher due to the need to prevent movement. Special non-linear techniques are necessary for the structural analysis of tension structures, since membranes undergo shape changes under varying load conditions and fabric materials exhibit complex stress-strain response. Computer-based finite element techniques such as EASY are used to solve these non-linear problems.
Many other software tools are used for projects, which include Finite Element Analysis, etc.
