“Frame Analysis of Concrete Buildings,”
Vanderbilt, M. D., and Corley, W. G.,
Concrete International: Design and Construction,
V. 5, No. 12, Dec. 1983, pp. 33-43.
This book contains the 7 keynote papers written by the industry experts, international renowned researchers and specialists and 73 technical papers which reflect the state-of-the-practice on the Analysis of Discontinuous Deformation: New development and Applications. These papers were selected after a rigorous review process. It represents the latest advances in numerical and analytical methods related to rock mechanics and engineering. Following the tradition of the series, the main schemes of the papers are on the key block theory and its engineering applications, the discontinuous deformation analysis (DDA) method and the numerical manifold method (NMM). However, other relevant topics, for example, the distinct/discrete element method, the meshless method, the finite element method in rock mechanics and engineering applications are also included. For rock masses where the discontinuities dominate their behaviour in a rock engineering system such as rock slopes and underground rock caverns, the analysis of discontinuous deformation is of critical importance in the stability analysis and engineering design. It is hoped that this book serves as a useful reference for both researchers and engineers on the new developments and applications of the various available modeling techniques and tools in this increasingly important field of rock mechanics and engineering. Topics covered: * Key Block Theory and Engineering Applications * Discontinuous Deformation Analysis (DDA) Method * Numerical Manifold Method (NMM) * Distinct/Discrete Element Method (DEM) * Application of UDEC, 3DEC and PFC codes * Meshless Method and Rock Engineering Applications * Contact Algorithms * Wave Propagation through Rock Joint and Jointed Rock Mass * Deformation Analysis of Heterogeneous Materials * Other Advanced Analytical and Numerical Methods in Rock Engineering * Experimental Techniques and Measurement of Discontinuous Deformation * Case Studies and Other Relevant Topics

2010 ASME BPVC, Section VIII, Division 2: Alternative Rules, Includes 2011 Addenda
Author: American Society of Mechanical Engineers | Size: 10.6 MB | Format:PDF | Quality:Original preprint | Year: 2011 | pages: 778
These rules provide an alternative to the minimum requirements for pressure vessels under Division 1 rules. In comparison the Division 1, Division 2 requirements on materials, design, and nondestructive examination are more rigorous; however, higher design stress intensify values are permitted. Division 2 rules cover only vessels to be installed in a fixed location for a specific service where operation and maintenance control is retained during the useful life of the vessel by the user who prepares or causes to be prepared the design specifications. These rules may also apply to human occupancy pressure vessels typically in the diving industry.

2010 ASME BPVC, Section VIII, Division 3: Alternative Rules for Construction of High Pressure Vessels
Author: American Society of Mechanical Engineers | Size: 4.8 MB | Format:PDF | Quality:Original preprint | Year: 2011 | pages: 384
This Division of Section VIII provides requirements applicable to the design, fabrication, inspection, testing, and certification of pressure vessels operating at either internal or external pressures generally above 10,000 psi. Such vessels may be fired or unfired. This pressure may be obtained from an external source, a process reaction, by the application of heat from a direct or indirect source, or any combination thereof. Division 3 rules cover vessels intended for a specific service and installed in a fixed location or relocated from work site to work site between pressurizations. The operation and maintenance control is retained during the useful life of the vessel by the user who prepares or causes to be prepared the design specifications. Division 3 does not establish maximum pressure limits for either Section VIII, Divisions 1 or 2, nor minimum pressure limits for this Division. Rules pertaining to the use of the UV3 Code symbol stamps are also included.

Plaxis 3D- Material datasets for plates: sheet pile wall in bending
Size: 94 KB
This is based on the Engineering Example as described in the PLAXIS 3D 2011 Material models manual.
In PLAXIS 3D plate elements are assumed to be plates with a rectangular cross-section. With some assumptions, the parameters for a material dataset for a sheet pile wall in bending can be calculated.
From the sheet-pile manufacturer, the following properties are known: t (wall thickness), h (total height), A (per m wall width), I1, Esteel and γsteel.
The structure is geometrically orthotropic with significant different stiffnesses in horizontal and vertical direction. It is known that the axial stiffness in vertical direction is larger than the effective stiffness in horizontal direction (E1 > E2). Moreover, the flexural rigidity against bending over the vertical direction, I1, is much larger than the stiffness against bending over the horizontal direction, I2, (I1 >> I2 say I1 ≈ 20 I2 and I1 >> I12 say I1 ≈ 10 I12)++).
Furthermore, it is assumed that the cross section area that is effective against shear deformation over the vertical direction is about 1/3 of the total cross section area, whereas the area that is effective against shear deformation over the horizontal direction is about 1/10 of the total cross section area. Finally, the Poisson's ratio's for sheet pile walls can be assumed zero.
With these assumptions, the situation could be modelled by selecting the model parameters in the following way:
In the attached Microsoft Excel spreadsheet, you can find these equations to determine the sheetpile wall parameters. Due to these assumptions to calculate the bending correctly, the axial stiffness is not correct, resulting in incorrect axial forces. The usage of this spreadsheet is at own risk. The PLAXIS program Disclaimer applies.
++) A factor of 20 is used here to move the bending stiffness over the first direction sufficiently small compared to the bending stiffness over the second direction, whilst the matrix condition is still OK. Note that in reality bending stiffness differences in order of 1000 may exist.

This book introduces the design of steel structures in accordance with AS 4100, the Australian Standard, in a format suitable for beginners. It also contains guidance and worked examples on some more advanced design problems for which we have been unable to find simple and adequate coverage in existing works to AS 4100.
The book is based on materials developed over many years of teaching undergraduate engineering students, plus some postgraduate work. It follows a logical design sequence from problem formulation through conceptual design, load estimation, structural analysis to member sizing (tension, compression and flexural members and members subjected to combined actions) and the design of bolted and welded connections. Each topic is introduced at a beginner’s level suitable for undergraduates and progresses to more advanced topics. We hope that it will prove useful as a textbook in universities, as a self-instruction manual for beginners and as a reference for practitioners.

This European Standard specifies requirements for unbound mixtures used for construction and maintenance of roads, airfields and other trafficked areas. The requirements are defined with appropriate cross-reference to EN 13242.
This European Standard applies to unbound mixtures of natural, artificial and recycled aggregates with a upper sieve size (D) from 8 mm to 90 mm and lower sieve size (d) = 0 at the point of delivery.
NOTE 1 Mixtures with an upper sieve size (D) greater than 90 mm are not covered by this European Standard but may be specified in the place of use.
NOTE 2 Water content of the mixture and the density of the installed layer are not specified mixture requirements. Both parameters are related to the control of the construction of the layer and are outside the scope of this European Standard.

Numerical Solution of Partial Differential Equations by the Finite Element Method
Author: Claes Johnson | Size: 2.74 MB | Format:DjVu | Quality:Scanner | Publisher: Cambridge University Press | Year: January 29, 1988 | pages: 280 | ISBN: 0521347580, ISBN-13: 978-0521347587
Professor Johnson presents an easily accessible introduction to one of the most important methods used to solve partial differential equations. The bulk of the text focuses on linear problems, however a chapter extending the development of non-linear problems is also included, as is one on finite element methods for integral equations. Throughout the text the author has included applications to important problems in mathematics and physics, and has endeavored to keep the mathematics as simple as possible while still presenting significant results.
