Category: Guide (part 1), technical report (part 2) and state-of-the-art report (part 3)
Year: 2000
As a background for an extension of the CEB/FIP Model Code 1990 (MC 90) it delivered firstly Bulletin 4. Similarly to what has been done before in the field of High Strength / High Performance Concrete the present guide identifies the lacunae in the existing MC90 and proposes supplementary or alternative solutions to be applied for lightweight aggregate concretes. The technical report identifies the research needs resulting from those clauses of MC 90 which need amendment, and for which more basic research should provide a better understanding of mechanical, physical and chemical processes. The state-of-art report documents 33 application examples of projects world-wide.

Alternate Path Method in Progressive Collapse Analysis: Variation of Dynamic and Nonlinear Load Increase Factors
Author: McKay, A., Marchand, K., and Diaz, M. | Size: 1.64 MB | Format:PDF | Quality:Original preprint | Publisher: ASCE, Engineering Structures. Vol. 48. Issue 4. | Year: 2012 March | pages: 666-673
In performing alternative path analyses for checking the potential of a structure to progressive collapse, most designers often choose static procedures, which tend to be simpler and less labor demanding. As progressive collapse is a dynamic and nonlinear event, the load cases for the static procedures require the use of factors to account for inertial and nonlinear effects. A number of inconsistencies have been identified in the way the existing guidelines applied dynamic and nonlinear load factors to their static approaches. As part of an existing effort to update the existing guidelines, this study looked into the behavior of a variety of reinforced-concrete and steel moment-frame buildings to investigate the magnitude and variation of the dynamic and nonlinear load increase factors. The study concluded that the factors in the existing guidelines tend to yield overly conservative results, which often translate into expensive designs and retrofits. This study identified new load increase factors and proposes a new approach to utilize these factors when performing alternative path analyses for progressive collapse.

The Converter software is plug-in for Autodesk Revit. It works equally well for 64-bit and 32-bit platforms, and it requires Revit API, .Net framework 3.5 and Microsoft Excel preinstalled. (If you don't have MS Excel but you are interested in our software we can create personal assembly for your business, please contact us for more information)
Converter can transfer 3D model from Autodesk Revit (2009, 2010, 2011) to CSI SAFE 12.x.x.
Elements which only belong to adjacent floors can be converted at the same time. The following instances are converted:
Beams
Columns (with local axis rotation parameter)
Slabs and curved edge slabs (drop panels and slab differ) with openings
Walls and curved walls
Grids
Groups of elements
There is possibility to adjust boundary elevations for columns and walls.
Revit 3D model can be transfered to Excel spreadsheet or SAFE *.f2k file.
Default design parameters can be assign during conversion:
Concrete and rebar materials (Materials database can be easily reset or adjusted with using Microsoft Excel).
Cover layers for slabs and beams

Rainfall and sampling uncertainties: A rain gauge perspective
Author: Gabriele Villarini, Pradeep V. Mandapaka, Witold F. Krajewski, and Robert J. Moore | Size: 733 KB | Format:PDF | Quality:Unspecified | Publisher: Wiley | Year: 2008 | pages: 12
Rain gauge networks provide rainfall measurements with a high degree of accuracy at
specific locations but, in most cases, the instruments are too sparsely distributed to
accurately capture the high spatial and temporal variability of precipitation systems. Radar
and satellite remote sensing of rainfall has become a viable approach to address this
problem effectively. However, among other sources of uncertainties, the remote-sensing
based rainfall products are unavoidably affected by sampling errors that need to be
evaluated and characterized. Using a large data set (more than six years) of rainfall
measurements from a dense network of 50 rain gauges deployed over an area of about
135 km2 in the Brue catchment (south-western England), this study sheds some light on
the temporal and spatial sampling uncertainties: the former are defined as the errors
resulting from temporal gaps in rainfall observations, while the latter as the uncertainties
due to the approximation of an areal estimate using point measurements. It is shown that
the temporal sampling uncertainties increase with the sampling interval according to a
scaling law and decrease with increasing averaging area with no strong dependence on
local orography. On the other hand, the spatial sampling uncertainties tend to decrease for
increasing accumulation time, with no strong dependence on location of the gauge
within the pixel or on the gauge elevation. For the evaluation of high resolution satellite
rainfall products, a simple rule is proposed for the number of rain gauges required to
estimate areal rainfall with a prescribed accuracy. Additionally, a description is given of
the characteristics of the rainfall process in the area in terms of spatial correlation
