  A simplified approach for seismic calculation of a tall building braced by shear wall

A simplified approach for seismic calculation of a tall building braced by shear wall

Author: Sid Ahmed Meftah, Abdelouahed Tounsi, Adda Bedia El Abbas | Size: 1.1 MB | Format: PDF | Quality: Original preprint | Publisher: Elsevier | Year: 2007 | pages: 10

Abstract :
In this paper an approximate hand-method for seismic analysis of an asymmetric building structure having constant properties along its height is presented. The building is stiffened by a combination of shear walls and thin-walled open section structures. Based on the continuum technique and d’Alembert’s principle, the governing equations of free vibration and the corresponding eigenvalue problem are derived. By applying the Galerkin technique, a generalized method is proposed for the free vibration analysis of coupled vibration of a building braced by shear walls and thin-walled open section structures. Simplified formulae are given to calculate the circular frequencies and internal forces of a building structure subjected to earthquakes. The utility and accuracy of the method is demonstrated by an numerical example, in which the proposed method is compared with finite element calculations.

Keywords: Tall building; Eigenfrequency; Continuous approach; Thin-walled structures; Coupling vibration; Internal forces

  REINFORCED CONCRETE WORKBOOK v1
Posted by: aslam - 08-02-2012, 03:08 AM - Forum: Engineering Spreadsheet - Replies (1)

REINFORCED CONCRETE WORKBOOK v1

Size: 161 KB


[Image: info.png]

This spreadsheet is intended for use by reinforced concrete detailers and designers.
It provides the user with the means to rapidly determine answers to the many
questions that reinforced concrete design and detailing raise. This spreadsheet
could be looked on as an electronic book with an index followed by pages containing
many individual calculators. Each calculator has a specific task to perform. The
Reinforced Concrete Workbook also acts as an aide memoir, reminding the user of the
various requirements to be observed.
The spreadsheet has been developed to comply with BS 8110 : Part 1 : 1997 and
BS 4466 : 1989 and Amendment No. 1 published 28 February 1990.

  Nonlinear Ordinary Differential Equations: Problems and Solutions

Nonlinear Ordinary Differential Equations: Problems and Solutions : a Sourcebook for Scientists and Engineers

Author: Dominic William Jordan, Peter Smith | Size: 3 MB | Format: PDF | Quality: Unspecified | Publisher: Oxford University Press | Year: 2007 | pages: 587 | ISBN: 0199212031, 9780199212033

[Image: 34682341473272417530.jpg]


[Image: info.png]

An ideal companion to the new 4th Edition of Nonlinear Ordinary Differential Equations by Jordan and Smith (OUP, 2007), this text contains over 500 problems and fully-worked solutions in nonlinear differential equations. With 272 figures and diagrams, subjects covered include phase diagrams in the plane, classification of equilibrium points, geometry of the phase plane, perturbation methods, forced oscillations, stability, Mathieu's equation, Liapunov methods, bifurcations and manifolds, homoclinic bifurcation, and Melnikov's method.

The problems are of variable difficulty; some are routine questions, others are longer and expand on concepts discussed in Nonlinear Ordinary Differential Equations 4th Edition, and in most cases can be adapted for coursework or self-study.

Both texts cover a wide variety of applications while keeping mathematical prequisites to a minimum making these an ideal resource for students and lecturers in engineering, mathematics and the sciences.

About the author (2007):
Prior to his retirement, Dominic Jordan was a professor in the Mathematics Department at Keele University. His research interests include applications of applied mathematics to elasticity, asymptotic theory, wave and diffusion problems, as well as research on the development of applied mathematics
in its close association with late 19th century engineering technologies. Peter Smith is a professor in the Mathematics Department of Keele University. He has taught courses in mathematical methods, applied analysis, dynamics, stochastic processes, and nonlinear differential equations, and his
research interests include fluid dynamics and applied analysis.

  Matrix Analysis and Applied Linear Algebra

Matrix Analysis and Applied Linear Algebra - Book and Solutions Manual

Author: Carl D. Meyer | Size: 6.9 MB | Format: PDF | Quality: Original preprint | Publisher: Society for Industrial and Applied Mathematics | Year: February 15, 2001 | pages: 890 | ISBN: 0898714540, ISBN-13: 978-0898714548

[Image: 62455717933671265041.jpg]

[Image: info.png]
This book avoids the traditional definition-theorem-proof format; instead a fresh approach introduces a variety of problems and examples all in a clear and informal style. The in-depth focus on applications separates this book from others, and helps students to see how linear algebra can be applied to real-life situations. Some of the more contemporary topics of applied linear algebra are included here which are not normally found in undergraduate textbooks. Theoretical developments are always accompanied with detailed examples, and each section ends with a number of exercises from which students can gain further insight. Moreover, the inclusion of historical information provides personal insights into the mathematicians who developed this subject. The textbook contains numerous examples and exercises, historical notes, and comments on numerical performance and the possible pitfalls of algorithms. Solutions to all of the exercises are provided.
