Graph theory gained initial prominence in science and engineering through its strong links with matrix algebra and computer science. Moreover, the structure of the mathematics is well suited to that of engineering problems in analysis and design. The methods of analysis in this book employ matrix algebra, graph theory and meta-heuristic algorithms, which are ideally suited for modern computational mechanics. Efficient methods are presented that lead to highly sparse and banded structural matrices. The main features of the book include: application of graph theory for efficient analysis; extension of the force method to finite element analysis; application of meta-heuristic algorithms to ordering and decomposition (sparse matrix technology); efficient use of symmetry and regularity in the force method; and simultaneous analysis and design of structures.

Environmental aerodynamics as part of wind engineering is provided. Of particular interest are the areas of pedestrian level winds and exhaust dispersion around buildings, which are introduced and discussed in the context of urban environment aerodynamics.
1. Introduction
The area of environmental aerodynamics examines those aspects of wind engineering that are closely related to the effects of wind to the built environment
in conjunction to basic environmental issues. Environmental aerodynamics is complementary to the so-called structural wind engineering, which deals with wind
loading on structures. Environmental aerodynamics requires fundamental knowledge of wind engineering principles (Stathopoulos and Baniotopoulos 2007) in order to study phenomena such as pedestrian level winds and their effect to humans; dispersion of pollutants; natural and hybrid ventilation; snow dispersion and accumulation; wind flows over various topographies, as well as in the urban or building environment; and the like. Particular emphasis is placed here on pedestrian level winds and dispersion of pollutants in the urban and building environment.

The purpose of this book is to present numerical methods for compressible flows. It is appropriate for advanced undergraduate and graduate students and specialists working in high speed flows. The focus is on the unsteady one-dimensional Euler equations which form the basis for numerical algorithms in compressible fluid mechanics.

The emphasis of this book is on engineering aspects of fluid turbulence. The book explains for example how to tackle turbulence in industrial applications. It is useful to several disciplines, such as, mechanical, civil, chemical, aerospace engineers and also to professors, researchers, beginners, under graduates and post graduates. The following issues are emphasized in the book: - Modeling and computations of engineering flows: The author discusses in detail the quantities of interest for engineering turbulent flows and how to select an appropriate turbulence model; Also, a treatment of the selection of appropriate boundary conditions for the CFD simulations is given. - Modeling of turbulent convective heat transfer: This is encountered in several practical situations. It basically needs discussion on issues of treatment of walls and turbulent heat fluxes. - Modeling of buoyancy driven flows, for example, smoke issuing from chimney, pollutant discharge into water bodies, etc

I am in doubt about the program to use for elaborating my future drawings.
Normally I use Autocad without any lisps added and the drawing process is going well enough.
Recently i started using Autocad Structural Detailing (reinforcement) for generating my drawings for a 2 story house and I was surprised to discover that it was by far not as efficient as i initially thought.
My question to you is can you recommend me a program beside Autocad or Autocad Structural Detaling, maybe an add-on to Autocad to ease the drawing stage?
Another question is related to Autocad Strucural Detaling. Do any of you have a tutorial, or a manual, for this program (reinforcement/steel) beside those near helpless user-guides from Autodesk?
A Warm WELCOME to all our visitors in this New Year!
We are so happy to see you and committed to provide you more better environment on CivilEA in this year also . We value and appreciate all the feedback we have received in past and in this year. Please keep yourself involved and share your thoughts with us as you are doing for past many years.
Seismic Design of Concrete Structures provides essential background instruction for the seismic design. Using relevant codes, this book presents topics from basic seismic concepts through detailing requirements. This edition references the Uniform Building Code and ACI 318, the most familiar code in engineering practice.

This comprehensive guide provides complete coverage of every aspect of the building technologist's profession. It details design and installation procedures, describes all relevant equipment and hardware, and illustrates the preparation of working drawings and construction details that meet project specifications, code requirements, and industry standards. The author establishes procedures for professional field inspections and equipment operations tests, provides real-world examples from both residential and nonresidential construction projects, and makes specific references to code compliance throughout the text.
This new edition incorporates changes in building codes, advances in materials and design techniques, and the emergence of computer-aided design (CAD), while retaining the logical structure and helpful special features of the first edition. More than 1,100 drawings, tables, and photographs complement and illustrate discussions in the text. Topics covered include:
* Heating, ventilating, and air conditioning systems- equipment and design
* Plumbing systems- equipment and design
* Electrical and lighting systems- equipment and design
* Testing, adjusting, and balancing procedures for all building systems
* Every aspect of the building technologist's profession, from the creation of working drawings through on-site supervision and systems maintenance
Extensive appendices include conversion factors; duct design data; test report forms for use in field work; design forms and schedules for electrical, HVAC, and plumbing work; and more.

The Ninth Edition reflects changes in CSA Standard S16-09, "Design of Steel Structures", regarding bolted and welded connections, laterally unsupported beams, block shear and composite beams.
This book serves as a comprehensive teaching text for universities and technical colleges, and also as a valuable reference document for practicing engineers. It offers an explanation of the philosophy and practical application of limit states design procedures and provides comments on design requirements contained in S16-09. Divided into 11 chapters, the book covers tension members, flexural members, columns, beam-columns, stability, fatigue behaviour, connections, plate girders, composite construction, and types and grades of structural steel
