  A House Project
Posted by: ykhackhack - 06-13-2012, 06:03 AM - Forum: Calculation Notes & Analysis Files - Replies (2)

I wanted to share a high end Single family residence plans
It is a 2 storey structure basically
And it is on piles. Grade beams and Structural slabs has been designed.
The layout plans has been changed by the Architect and owner so many times. They kept removing supports, making larger rooms, larger spans. Not realizing that we had limited depths for beams.
Air condition duct locations was not even designed yet
I had to construct a 3D object-based model in order to make quick changes and keep up with them.

Finally It was built successfully
I would add the finish pictures when I find it.
Enjoy

Earthquake Thermodynamics and Phase Transformations in the Earth's Interior

Author: Roman Teisseyre, Eugeniusz Majewski | Size: 35 MB | Format: PDF | Quality: Unspecified | Publisher: NA Press | Year: 2001 | pages: 697 | ISBN: 0126851859-9780126851854

INTERNATIONAL GEOPHYSICS SERIES, Volume 76

Earthquake thermodynamics offers us a microscopic model of earthquake sources. Through the thermodynamic approach, the authors arrive at the fascinating question of posssibility of earthquake prediction. In general, the Earth is considered here as a multicomponent system. Transport phenomena as well as wave propagation and shock waves are considered in this system subjected also to chemical and phase transformations.

LRFD Steel Design Using Advanced Analysis (New Directions in Civil Engineering)

Author: Wai-Fah Chen | Size: 0 MB | Format: PDF | Quality: Unspecified | Publisher: CRC-Press | Year: March 30, 1997 | pages: 464 pages | ISBN: 0849374324

[Image: 03826558954462120265.jpg]


[Image: info.png]

It is intended for both the graduate student and the practicing engineer. Previous knowledge of the subject is not necessary, but familiarity with methods of elastic analysis and conventional LRFD design is expected. The advanced analysis in the book is presented in a practical and simple manner, with attention directed to both analysis and design, emphasizing the direct use of the methods in engineering practice. This is a great introduction to an exciting new trend in structural engineering!

  Dynamic stability of non-linear shells of revolution under consideration of the fluid
Posted by: mybest - 06-12-2012, 02:50 PM - Forum: Journals, Papers and Presentations - No Replies

Dynamic stability of non-linear shells of revolution under consideration of the fluid–soil–structure interaction

Author: W. Wunderlich, B. Schäpertöns, C. Temme | Size: 1 MB | Format: PDF | Quality: Original preprint | Publisher: Wiley, Journal International Journalfor Numerical Methods in Engineering | Year: 15 August 1994 | pages: 2679–2697


[Image: info.png]

The dynamic behaviour of liquid-filled shells of revolution is investigated considering the soil–structure interaction and the fluid–structure interaction, respectively. In the circumferential direction the loads and variables are approximated by Fourier series. The shell is modelled through shell ring elements including non-linear behaviour, coupled with isoparametric continuum ring elements and special infinite elements for the soil and isoparametric pressure ring elements for the fluid. Transient loadings like earthquake excitation and the non-linearities of the shell and the soil require an analysis in the time domain. To reduce the size of the problem, linear parts of the system are condensed by the substructure technique. The soil region is divided into two parts, a near field permitting non-linearities like plastification or uplifting of the shell, and a far field for the treatment of radiation of energy.

The boundary conditions for the shell footing have a strong influence on the distribution of the axial membrane forces and, hence, on the stability limit, which is mostly governed by plastic collapse and caused by the dynamically activated pressure acting on the tank wall. It is shown how the soil properties influence the dynamic stability of the shell under harmonic excitation and under realistic earthquake motion.

  Micropolar Theory of Elasticity
Posted by: freequo - 06-12-2012, 12:57 PM - Forum: Archive - No Replies

Micropolar Theory of Elasticity

Author: Janusz Dyszlewicz | Size: Unknown MB | Format: PDF | Quality: Unspecified | Publisher: Springer | Year: 2004 | pages: 369 | ISBN: 3540418350

[Image: 79343774787045302825.jpg]


[Image: info.png]

The monograph Micropolar Theory of Elasticity is devoted to the asymmetric theory of elasticity and thermoelasticity, aiming at researchers and postgraduate students in solid mechanics and applied mathematics, as well as mechanical engineers. It offers various new results including the basic field equations, general methods of integration of basic equations, formulations of problems, as well as solutions to particular problems. The presented general solutions cover those of Galerkin, Green-Lamé and Papkovitch-Neuber type, whereas the formulations include the displacement-rotation problems as well as pure stress problems of asymmetric elastodynamics. Solutions to stationary 3D and 2D problems for a half-space, and singular solutions to 3D and 2D asymmetric elastodynamics and the thermoelasto-dynamics problems for an infinite space are given.

  Microcontinuum Field Theories I: Foundations and Solids
Posted by: freequo - 06-12-2012, 12:49 PM - Forum: Archive - No Replies

Microcontinuum Field Theories I: Foundations and Solids

Author: A. Cemal Eringen | Size: Unknown MB | Format: PDF | Quality: Unspecified | Publisher: Springer | Year: 1999 | pages: 364 | ISBN: 0387986200

[Image: 23962249190838952765.jpg]


[Image: info.png]

Microcontinuum field theories extend classical field theories to microscopic spaces and short time scales. This volume is concerned with the kinematics of microcontinua. It begins with a discussion of strain, stress tensors, balance laws, and constitutive equations, and then discusses applications of the fundamental ideas to the theory of elasticity. The ideas developed here are important in modeling the fluid or elastic properties of porous media, polymers, liquid crystals, slurries, and composite materials.
