  Plastic design of low-rise frames
Posted by: david-smith - 05-01-2012, 10:34 PM - Forum: Archive - No Replies

Plastic design of low-rise frames
Michael Rex Horne, L. J. Morris
[Image: 93043684517214622752.jpg]
Publisher MIT Press, 1982
Original from the University of California
Digitized 18 Oct 2008
ISBN 0262081237, 9780262081238
Length 238 pages
he technique of plastic design has many advantages over the traditional elastic design technique. The methodology was developed in large part by M. R. Horne and his co-workers, and first came into wide-spread practical application in Britain. With the publication of this book, American designers and engineers will be given easy access to the latest developments in the theory and practice of plastic design.The advantages of this technique for simple beam systems and single-story buildings are considerable: plastic design represents a more rational approach and the analysis can be accomplished quickly and directly, and it facilitates economies in the use of materials. Moreover, the methods can be readily extended to buildings that are several stories (four or five) high.The first chapter reviews the fundamental methods of plastic analysis. Following chapters take up such topics as plastic moment distribution, modifying factors in plastic bending, frame stability and deflections (including the destabilizing effects of column axial loads on frames), the rigid-plastic behavior of a frame, and the elastic-plastic behavior of frames. A final chapter explains various practical considerations, such as joint design and the stiffening effects of cladding. All the chapters are linked so that the flow of the presentation is even throughout.The book considers whole structures as well as the behavior of various elements. Numerous worked examples are presented, some of which are taken from actual designs.M. R. Horne is Beyer Professor of Civil Engineering at the University of Manchester and author of Plastic Theory of Structures. L. J. Morris is a senior lecturer on the Manchester civil engineering faculty. The book is the second in the MIT Press Series in Structural Mechanics, edited by H. Max Irvine.

  Plastic Design of Steel Plate Shear Walls: Introduction to Performance Based Seismic
Posted by: david-smith - 05-01-2012, 10:20 PM - Forum: Archive - No Replies

Plastic Design of Steel Plate Shear Walls:
Introduction to Performance Based Seismic Design of Steel Plate Shear Walls
Farooq Adam
[Image: 29303358968653203253.jpg]
Publisher VDM Verlag, 2010
ISBN 3639296877, 9783639296877
Length 180 pages
The unstiffened steel plate shear wall (SPSW) system has emerged as a promising lateral load resisting system in recent years. However, seismic code provisions for these systems are still based on elastic force-based design methodologies. Considering the ever-increasing demands of efficient and reliable design procedures, a shift towards performance-based seismic design (PBSD) procedure is proposed in this work. The proposed PBSD procedure for SPSW systems is based on a target inelastic drift and pre-selected yield mechanism. This design procedure is simple, yet it aims at an advanced design criterion. The proposed procedure is tested on a four-story test building with different steel panel aspect ratios for different target drifts under selected strong motion scenarios. The designs are checked under the selected ground motion scenarios through nonlinear response-history analyses. The actual inelastic drift demands are found to be close to the selected target drifts. In addition, the displacement profiles at peak responses are also compared with the selected yield mechanism.

Posted by: betoncu - 05-01-2012, 05:54 PM - Forum: Archive - No Replies

Hi All,

I am doing an MS thesis about magnetic effects of water on concrete strength and consistency. There is a lack of sources about this issue. I need much more papers and reports. So if anyone dealing with this issue or have documents about it, please share with me.

Thanks lot.

Hi,

I am not sure if there is a ebook of The New Concrete( written by Mario Collepardi). It is a very useful book. If it can be found as pdf, it will be great.

Thanks

  ARC-Slag Remelting of Steel and Alloys
Posted by: david-smith - 05-01-2012, 05:13 PM - Forum: Mechanics & Material Technology (Elasticity, Plasticity and Nonlinearity) - No Replies

ARC-Slag Remelting of Steel and Alloys

Author: B I Medovar (Author), V Ya Saenko (Author), G M Grigorenko (Author), Yu M Pomarin (Author), V I Kumysh (Author) | Size: 6 MB | Format: PDF | Quality: Original preprint | Publisher: Cambridge International Science Publishi | Year: 1997 | pages: 160 | ISBN: 1898326215-978-1898326212

[Image: 91558573124273136687.jpg]

The book describes the method of remelting consumable electrodes with an electric are burning between the surface of a liquid slag bath and a consumable electrode in a water-cooled copper mould. The method combines the possibilities of treatment of liquid metal with the electric arc in the gas atmosphere and the liquid slag and the advantages of plasma-arc and electro slag remelting. The technological possibilities, design features of melting systems and results of experimental and industrial melting trials of steels and alloys are described. In addition to remelting structural steels, special attention is given to the possibility of alloying the metal with nitrogen from the gas phase, without using expensive nitrogen-bearing nonmetallic compounds, e.g. silicon nitride. It is shown that arc slag remelting can also be used efficiently in producing ingots of titanium and its alloys. The results obtained in this method are compared with electro slag remelting and plasma arc remelting. Data on energy consumption and metal quality are also presented.
