Hi to all
Does anybody know any good english ( or other ) forum about SOFiSTiK Software,
I know one which is official ( at official german site ) forum, but really poor with discussions.
OFFSHORE STANDARD DNV-OS-C105 STRUCTURAL DESIGN OF TLPS (LRFD METHOD)
Author: DET NORSKE VERITAS | Size: 0.3 MB | Format:PDF | Publisher: DET NORSKE VERITAS | Year: 2007 | pages: 29
301 A TLP is usually applied for drilling, production and export of hydrocarbons. Storage may also be a TLP function.
302 A TLP may be designed to function in different modes, typically operation and survival. Also horizontal movement (e.g. by use of catenary or taut mooring) of TLP above wells may be relevant. Limiting design criteria when going from one mode of operation to another shall be established.
303 The TLP unit should also be designed for transit relocation, if relevant.
304 For novel designs, or unproved applications of designs where limited, or no direct experience exists, relevant analyses and model testing shall be performed which clearly demonstrate that an acceptable level of safety can be obtained, i.e. safety level is not inferior to that obtained when applying this standard to traditional designs.
305 Requirements concerning riser systems are given in DNV-OS-F201.
306 In case of application of a catenary or taut mooring system in combination with tendons, reference is made to DNVOS-E301.
307 Requirements related to stability (intact and damaged) are given in Sec.6 for ULS condition and Sec.8 for ALS condition.

This European standard deals with the requirements, the basic performance criteria and evaluation of conformity for precast floor plates made of reinforced or prestressed normal weight concrete according to EN 1992-1-1:2004, used in conjunction with cast-in-situ concrete (topping) for the construction of composite floor slabs. Annex B gives different types of composite slabs made with floor plates. These floor plates, with or without void formers, can include lattice girders or stiffening ribs incorporated during the precasting. They shall be manufactured in factories by casting, slip forming or extrusion. The products covered by this standard are intended to be used as part of structural floors in applications such as:
- floors and roofs of buildings (including industrial and storage buildings, public buildings as schools, hospitals, etc.);
- parking/circulation areas;
- cover for culverts;
- etc.
The products may be used in seismic areas provided they fulfil the requirements specific to this use.
This standard does not cover:
- reinforced floor plates with a nominal thickness less than 40 mm;
- prestressed floor plates with a nominal thickness less than 50 mm;
- floor plates with a very smooth upper face, such as defined in 6.2.5 of EN 1992-1-1:2004.

Hello to All,
I need calculation notes or Design Example (Preferably CMAA) along with the references for the COMPLETE Design Steps of EOT Overhead Crane (Single & Double Girders), Excel Spredsheet will also be appreciated.
Kindly share some above mentioned docs. BS Code can also help me...
I have Built-up Box Girder to Design....
This Published Document gives guidance on the use of BS EN 13108-1, BS EN 13108-4, BS EN 13108-5, BS EN 13108-8, BS EN 13108-20 and BS EN 13108-21. Clauses 1 to 10 of this Published Document give general guidance and background information on BS EN 13108. Annex B provides guidance, based on the requirements formerly specified in BS 4987, for producing asphalt concrete that conforms to BS EN 13108-1; Annex C gives similar guidance, based on the requirements formerly specified in BS 594-1, for producing hot rolled asphalt that conforms to BS EN 13108-4; and Annex D provides guidance for producing stone mastic asphalt that conforms to BS EN 13108-5. This Published Document does not give guidance on BS EN 13108-2, BS EN 13108-3, BS EN 13108-6 or BS EN 13108-7 as these are either little used in the UK or covered by other guidance. This document’s application is for roads and other paved areas, but excluding airfields, detailed provisions for which are specified elsewhere.
NOTE 1 Porous asphalt, which was included in BS 4987, is now covered by BS EN 13108-7. Mastic asphalt mixtures previously defined in BS 1447 are now covered by BS EN 13108-6.
NOTE 2 There are several asphalt mixtures in general use which were not historically covered by British Standards but which are now covered in BS EN 13108. These are stone mastic asphalt, covered by BS EN 13108-5, and asphalt concrete for very thin layers (thin surfacing), covered by BS EN 13108-2.

Dear member.
Now, I'm in the 3rd year of undergraduate program and I have a plan to Redesign of Reinforced Concrete Building as my Final Project.
As my plan, I need a complete set of RC building 10 - 12 storey. I really Appreciate if another member can help me.
Thanks..
Parametric study and simplified design of tuned mass dampers
Author: Rahul Rana and T. T. Soong | Size: 0.966 MB | Format:PDF | Publisher: E L S E V I E R,Engineering Structures, Vol. 20 | Year: 1998 | pages: 12
This paper summarizes the results of a parametric study performed to enhance the understanding of some important characteristics of tuned mass dampers (TMD). The effect of detuning on some of the TMD parameters on the performance is studied using steady-state harmonic excitation analysis and time-history analysis. The El Centro and Mexico excitations are used for time-history analysis. The effects of tuning criteria and significance of numerical tuning are
also studied. The correspondence between the design of a TMD for a SDOF structure and a certain mode of a MDOF structure is drawn to simplify TMD design to control a single mode of a multi modal structure. An example is given to illustrate the design procedure. Investigations are made regarding controlling multiple structural modes using multi-tuned mass dampers (MTMD).
