Hi, i have civil 3d land companion 2009 and just installed civil 3d 2010 in the same PC, Land is working normal but when i try to run civil 3d it does nothing, i mean nothing, it just load up the LMU.exe file and stay there forever.
by the way i just did an unistall-reinstall procedure.
Earthquake Spectra, the professional journal of the Earthquake Engineering Research Institute (EERI),
is published quarterly in both printed and online editions in February, May, August, and November.
The printed edition is sent to EERI members as part of their membership benefits.
EERI established Earthquake Spectra with the purpose of improving the practice of earthquake hazards mitigation, preparedness, and recovery.
It is intended to serve the informational needs of the diverse professionals engaged in
earthquake loss reduction: civil, geotechnical, mechanical, and structural engineers; geologists, seismologists,
and other earth scientists; architects and city planners; public officials; social scientists; and researchers in all these disciplines.
Spectra serves as the publication of record for the development of earthquake engineering practice, earthquake codes and regulations,
earthquake public policy, and earthquake investigation reports. Manuscripts published in Earthquake Spectra are peer reviewed.
Periodically, EERI publishes special issues of Earthquake Spectra, either as theme issues or as reconnaissance reports on major earthquakes.
All back issues can be viewed and searched at the Spectra Online site

Many mechanics and physics problems have variational formulations making them appropriate for numerical treatment by finite element techniques and efficient iterative methods. This book describes the mathematical background and reviews the techniques for solving problems, including those that require large computations such as transonic flows for compressible fluids and the Navier-Stokes equations for incompressible viscous fluids. Finite element approximations and non-linear relaxation, augmented Lagrangians, and nonlinear least square methods are all covered in detail, as are many applications.
"Numerical Methods for Nonlinear Variational Problems", originally published in the Springer Series in Computational Physics, is a classic in applied mathematics and computational physics and engineering. This long-awaited softcover re-edition is still a valuable resource for practitioners in industry and physics and for advanced students.

"Finite Element Simulation of Heat Transfer"
Jean-Michel Bergheau, Roland Fortunier,
Wiley-ISTE | 2008 | ISBN: 1848210531 | 320 pages
PDF | 2 MB
This book introduces the finite element method applied to the resolution of industrial heat transfer problems. Starting from steady conduction, the method is gradually extended to transient regimes, to traditional non-linearities, and to convective phenomena. Coupled problems involving heat transfer are then presented. Three types of couplings are discussed: coupling through boundary conditions (such as radiative heat transfer in cavities), addition of state variables (such as metallurgical phase change), and coupling through partial differential equations (such as electrical phenomena).? A review of the various thermal phenomena is drawn up, which an engineer can simulate. The methods presented will enable the reader to achieve optimal use from finite element software and also to develop new applications.

I need the paper:
"Johnston , I.W., Lam, T.S.K. and Williams, A.F. (1987). Constant normal stiffness direct shear testing for socketed pile design in weak rock. Geotechnique. Vol. 37, pp. 83-87."
Can anyone help me?
Thank in advance.

Here is a short overview of the most interesting part of the bridge:
SELF-ANCHORED SUSPENSION SPAN
If one single element bestows the status of world-class on the new Bay Bridge, it is the Self-Anchored Suspension (SAS) Span. This engineering marvel will be the world's largest SAS bridge (2,047 feet).
The SAS is not just another suspension bridge. Traditional main cable suspension bridges have twin cables with smaller suspender cables connected to them. These cables hold up the roadbed and are anchored to separate structures in the ground. While there will appear to be two main cables on the SAS, there is actually only one. This single cable is anchored within the eastern end of the roadway. The cable is carried over the tower and wraps around the two side-by-side decks at the western end.
The SAS, and the rest of the new East Span, is being built to the north of the existing bridge. By switching from the existing East Span's double-decks to side-by-side roadways, drivers will enjoy unencumbered and expansive views of the Bay Area as they pass beneath an angled canopy of suspension cables. The SAS, and Skyway, will feature a 15-foot-wide cantilevered bicycle and pedestrian path on the eastbound side of the bridge, so those traveling on foot or two wheels between Oakland and Yerba Buena Island (YBI) can enjoy those majestic views of the Bay as well.
The new SAS bridge echoes the existing towers of the West Span, as well as the towers on the Golden Gate Bridge. All vertical elements of the SAS – the tower, piers and lights – have been designed to emphasize its clean modern lines. Adding to its distinctiveness is the asymmetrical design. The bridge will have a longer forward span (east of the tower), which will provide a more gradual transition from the gently sloping Skyway, and will give the new East Span a unique silhouette. While the new East Span will have side-by-side decks, those decks will transition to a double-deck structure at YBI, to carry traffic through the YBI tunnel and onto the West Span.
The design features state-of-the-art seismic safety elements and will provide the East Span with a modern, streamlined appearance. Rising 525 feet above mean sea level and embedded in rock, the single-tower span is designed to withstand a massive earthquake. The single steel tower will be made up of four separate legs connected by shear link beams, which function in the same way as a fuse in an electrical circuit. These beams will absorb most of the impact from an earthquake, preventing damage to the tower legs. In addition, if one of the legs is damaged, the other legs will keep the bridge standing.
======================================================================
On this website you can find a lot of interesting videos and facts about the bridge which is currently under construction, it’s a very well organized website, be sure to check all of the features!
