This book introduces methods for solving the technical and economic problems posed by water reservoirs, so as to ensure they have the best possible economic and social effect. The significance of reservoirs and the development of their function in water management is assessed, and they are classified according to origin and placing. Among the methods for solving the reservoir's function, both graphical and numerical procedures are described, based on the probability theory and mathematical statistics. In the explanation of the supply function of the reservoirs, attention is paid to the processing of hydrological data, the respective probability distribution is assessed, the theory of stochastic processes is explained, and methods of modelling the sequence of mean annual and monthly discharges are mentioned. The demands of consumers and the reliability of water supply are analysed. All types of reservoir discharge control are presented, i.e. multi-year, annual, short-term and compensation. A solution is given for the discharge control in reservoir systems and in special cases of water management, as well as in individual reservoirs.

Author: Paolo Rugarli | Size: 6.3 MB | Format:PDF | Publisher: Thomas Telford Ltd | Year: 2010 | pages: 424 | ISBN: Thomas Telford Ltd
Description
Structural Analysis with Finite Elements reveals the theory behind the finite element (FE) method as it relates to structural engineering and explains how to overcome commonly encountered problems and errors found in everyday structural modelling with finite element software.
Drawing on nearly 20 years of experience as a structural engineer and FE software developer, Paolo Rugarli gives readers clear guidance on the fundamental principles of the FE method, demonstrating through practical examples how these principles apply to the kind of FE modelling that goes on every day in structural design departments.
Explaining computational methods from the software users' point of view, Structural Analysis with Finite Elements also points out the risks involved in using FE software packages, analysing typical errors and problems, with extensive reference to real world examples.
Key features of the book:
* Focuses on the practical structural engineering applications of FEM
* Goes back to first principles
* Gives readable, accessible and concise explanations
* Identifies common pitfalls that analysts encounter when devising structural models
* Applicable to all FEM software
Containing the theory and practice of finite element analysis, this book will prove a valuable guide for structural engineers and students worldwide.

This is an elementary text book for the civil engineering students with no prior background in point-set topology. This is a rather terse mathematical text, but provided with an abundant supply of examples and exercises with hints.

Abstract
Gives an overview of ground behaviour and geotechnics, but focuses on shallow foundations for low-rise buildings. Covers regulations and legislation for foundations and contaminated land, types of ground, soil behaviour and ground assessment. Also focuses on foundation design and foundations on difficult ground, and finally, looks at foundation movement and damage, remedial treatment and underpinning, and ancillary works (hardcore, soakaways, drains, small embankments, small retaining walls, freestanding walls).

Finite Element (FE) software is an essential tool for most structural design engineers, and at the cost of most commercial FE software, it had better be essential. The commercial FE software used by many engineering firms will provide you with more computer-output than you could read in a month and more than you can understand in a year. Commercial programs are great for impressing clients, and great for performing extensive analysis when really needed. But in design of frame-type structures, rarely is all that power andUnderstanding FE theory allows the user to in many cases forego commercial software and use more basic software, such as the FE spreadsheet. In 10 years of private practice, I haverelied almost exclusively on a FE spreadsheet for analyzing frame-type structures. That spreadsheet is presented in this course as a teaching tool and as a practical, effective design tool. The spreadsheet is limited to 2-dimensional frames of about 50 nodes, but if a problem is within that range it is easier to use, easier to understand, easier to port, easier to check and much less expensive than commercial programs using exce
