  Structural Analysis with the Finite Element Method. Linear Statics: Volume 1 & 2
Posted by: babak - 03-08-2010, 02:11 AM - Forum: Finite Element Methods - Replies (14)


Structural Analysis with the Finite Element Method

[Image: 01624057374678098644.jpg]

[Image: info.png]
STRUCTURAL ANALYSIS WITH THE FINITE ELEMENT METHOD
Linear Statics
Volume 1 : The Basis and Solids
Eugenio Oñate

The two volumes of this book cover most of the theoretical and computational aspects of the linear static analysis of structures with the Finite Element Method (FEM). The content of the book is based on the lecture notes of a basic course on Structural Analysis with the FEM taught by the author at the Technical University of Catalonia (UPC) in Barcelona, Spain for the last 30 years.

Volume1 presents the basis of the FEM for structural analysis and a detailed description of the finite element formulation for axially loaded bars, plane elasticity problems, axisymmetric solids and general three dimensional solids. Each chapter describes the background theory for each structural model considered, details of the finite element formulation and guidelines for the application to structural engineering problems. The book includes a chapter on miscellaneous topics such as treatment of inclined supports, elastic foundations, stress smoothing, error estimation and adaptive mesh refinement techniques, among others. The text concludes with a chapter on the mesh generation and visualization of FEM results.

The book will be useful for students approaching the finite element analysis of structures for the first time, as well as for practising engineers interested in the details of the formulation and performance of the different finite elements for practical structural analysis.

  Blast effects on buildings

Blast effects on buildings

[Image: 09886816266892836075.jpg]

[Image: info.png]
Blast effects on buildings: Design of buildings to optimize resistance to blast loading
Thomas Telford Publications | English | ISBN 0727720309 | 516 pages | PDF | 11.66 MB | 1995

This book is aimed at all engineers and architects involved in the design of building structures, and should enable them to have a better understanding of their own and their client's responsibilities in providing buildings which, in the event of an explosion, minimize damage to people and property.

Following this introduction putting the subject in context, the book starts with some basic guidelines for enhancing the resilience of buildings to blast loading (Chapter 2). An explanation of the nature of explosions and the mechanism of blast waves in free air is then given. This leads to a discussion of the loading that explosions place on structures, both inside and out, and the concept of an idealized loading is introduced (Chapter 3). The response of buildings, people and equipment to blast loading is illustrated. A method of analysis is suggested whereby the strain energy absorbed is equated to the work done or kinetic energy imparted and the structure reduced to a single degree of freedom (Chapter 4).

  Detailed Example of a Tall Shear Wall Building Using PERFORM 3D
Posted by: jagdish63 - 03-07-2010, 11:03 PM - Forum: Archive - Replies (2)

Hello
I was woundering if any one could post up the link for Detailed Example of a Tall Shear Wall Building Using PERFORM 3D DVD-ROM.

Description



A book and data disc reference set containing modeling guidelines for tall shear walls and a detailed example of a three-dimensional, 13-story shear wall building using CSI’s PERFORM 3D.

This set includes 1) a 90-page book by Dr. Graham H. Powell, featuring detailed notes, calculations, and illustrations to walk you through the example, step-by-step, 2) the data disc in DVD format containing supporting files and models, supplemental notes, information about current research and 3) a PDF version of Dr. Powell’s book; and fully-featured 30-day trial version of PERFORM 3D.

Thank you

  Structural Analysis with Applications to Aerospace Structures by Bauchau & Craig

Structural Analysis with Applications to Aerospace Structures by Bauchau & Craig

[Image: screen.png]
[Image: 37027628956497353370.jpg]

[Image: info.png]
O.A. Bauchau, J.I. Craig, "Structural Analysis: With Applications to Aerospace Structures"
Springer | 2009 | ISBN: 9048125154 | 943 pages | PDF | 12,6 MB

The authors and their colleagues developed this text over many years, teaching undergraduate and graduate courses in structural analysis courses at the Daniel Guggenheim School of Aerospace Engineering of the Georgia Institute of Technology.


The emphasis is on clarity and unity in the presentation of basic structural analysis concepts and methods. The equations of linear elasticity and basic constitutive behaviour of isotropic and composite materials are reviewed. The text focuses on the analysis of practical structural components including bars, beams and plates. Particular attention is devoted to the analysis of thin-walled beams under bending shearing and torsion. Advanced topics such as warping, non-uniform torsion, shear deformations, thermal effect and plastic deformations are addressed. A unified treatment of work and energy principles is provided that naturally leads to an examination of approximate analysis methods including an introduction to matrix and finite element methods.

This teaching tool based on practical situations and thorough methodology should prove valuable to both lecturers and students of structural analysis in engineering worldwide.

This is a textbook for teaching structural analysis of aerospace structures. It can be used for 3rd and 4th year students in aerospace engineering, as well as for 1st and 2nd year graduate students in aerospace and mechanical engineering.

  How to model in etabs with full span opening of shearwall at the bottom.

How to model in etabs with full span opening of shearwall at the bottom

[Image: info.png]
See below screenshot to make it clear about my question.I have an opening in the bottom of 12 story shearwall, it is due to the ramp.
Can I humbly ask how to model properly the shearwall to have realistic behavior in this case?
Thank in advance..

Another question:
Some etabs model, the support they used is hinges..I usually used fixed support..What is the proper way for the cast in situ.

  Reducing the time for calculations in SAP
Posted by: ivanveliki - 03-06-2010, 09:30 PM - Forum: Archive Problem - Replies (2)

I have a model with compression only frames in SAP2000 v14. When there are many nonlinear elements, the time needed for calculation the model exceedes several hours. Last time it took 3h45min to calculate a model with 50 loading steps (1 static nonlinear case).
The most funny thing is that in the manual it is said that SAP2000 has a "very fast" nonlinear solver.
Reducing the steps doesn't help much.

There are some nonlinear parameters to setup, but I do not fully understand their meaning. I do not want to reduce significantly the amount of the loading steps. I have tried to reduce the number of iterations, but the null steps becomes more than the successful steps and as a result it saves only 1 or 2 steps out of 100.

The same model in MIDAS GEN is calculated for max 10min, but I have a feeling that the results are not quite right and I want to compare the results.

Is there a way to reduce the calculation time somehow?
