Dear eNews reader,

Currently there is a lot going on in the construction world and through this eNews we like to fill you in on various topics. As always, our regular items inform you about the latest state of technology, the developments on the market and striking projects. We gladly invite you to one of the many events SCIA organises or in which we participate.

Here are the items for this month:

» SCIA Corporate News: 4D design and construction
» Product News: New possibilities and efficiency with design software Allplan 2005.1  
» The Market: 2 billion people to be housed from now up to 2030

 SCIA Corporate News: 4D design and construction  
 
In the August edition of the Structural Engineering International magazine an interesting article was published by a well-known contractor in Germany, explaining why they decisively have chosen the 4D way of design.
4D means 3D modelling enhanced with the factor time, representing chronological relationships.

Admitting the need to change the culture within their company, their experiences are worth to be repeated: in the early stage of every project the ratio of time needed to explain a problem, to the time needed to solve the problem is approximately 80 to 20%. Therefore communication based on 3D models with interactive imaging results in vivid discussions. Geometric incompatibilities (especially between an architectural and a structural engineering design) are identified at an early stage, improving the design quality. Planning of a construction project is a difficult science; simulation of construction sequences results in alternative options for a better and more cost-effective solution. Also the construction progress is visualised and recorded with 4D simulation. Photo realistic images of projects are ... more
 
 
   New possibilities and efficiency with design software Allplan 2005.1  


With Allplan 2005.1 Nemetschek and SCIA have released various new modules.

The BIM concept has really given shape to in the new module for modelling steel constructions. With the parametric templates in Allplan it is possible to model and modify steel constructions, including connections. It is also possible to use the powerful 3D modeller of SCIA.ESA PT within the Allplan environment. As is customary in Allplan, steel objects and all other elements, such as concrete beams, brickwork walls, stairways, reinforcement, … are managed centrally in 1 model.
Within Allplan an overview list with steel profiles is made up and the desired views and cuts can be generated. For presentation purposes, the steel structure can be made up with colours, textures, environmental objects such as thegrounds, the background (trees, people, …), in this way photo-realistic images are created, stationary or moving.

Allplan also disposes of a ‘one-file’ approach. A lot of drawing software is not built-up with regard to projects but is based on one single file, e.g. DWG, dgn, dxf. Allplan has the disposal of ... more

 
   
 The market: 2 billion people to be housed from now up to 2030  
 
Whereas about half of the world population (3 billion) lives in urban zones - including 30% in slums -, the ‘Program of the United Nations for the human settlements’ (UNO Habitat) provides in its last annual report that nearly 2 billion additional man will need housing from today until 2030.

According to an official statement of ‘UNO Habitat’ accompanying its annual report published last week, we quote: "during the next 25 years, more than 2 billion people will require housing, that is, 96.150 residences would have to be built each day, more specifically 4.000 per hour from today until 2030"
Under the heading "Financing of urban residences", the World Report 2005 on human settlements underlines the challenges the international community must face in order to be able to finance the development of urban residences, concentrating mainly on the needs of the poorest populations and taking the objectives into account which are stated in the ‘Millennium Objectives for Development’ (MOD). If financial resources will not be invested in the development of urban residences, the two billion people who require housing in the next 30 years will fall into the trap of urban poverty and they will live under deplorable conditions, the report predicts.

"The migrations of the rural zones towards ... more
 
   
    ESA-Prima Win was used to compare the Belgian Standard with the Eurocode  
 


SCIA-software is also used at universities and colleges during the courses, practices and for theses. It happens quite often that a thesis is entered in a contest and that it receives a prize. On repeated occasions this has been the case with the ‘Student Steel Prize’.

Recently, Mr Ben Cools, student at the ‘Vrije Universiteit Brussel’, submitted to us a very interesting thesis. It regards a comparative study between the Belgian standards and the Eurocodes. It has been carried out in cooperation with Victor Buyck Steel Construction from Eeklo. Prof. ir. Wim Hoeckman, university teacher for steel structures and bridge construction, acted as his supervisor. For this study, the new bascule bridge ‘Boulevardbrug’ of Willebroek has been recalculated according to the Eurocodes, originally the bridge was calculated taking the Belgian standards into account. The recalculation has been executed, just like the original calculation, with the SCIA software solution ESA-Prima Win.

The bridge has a span of 65m, the largeness is 16m, it weighs 900 tons and the counterweight is 1200 tons.

   Tips & Tricks: Wind and Snow generator in SCIA.ESA PT 5.2  
 
One of the most tedious tasks to input are the wind and snow loads for a construction. This is mainly caused by the fact that wind from both directions needs to be modelled, overpressure, under pressure, ...

The latest version, SCIA.ESA PT 5.2 can generate the wind and snow load cases automatically on the frames of the structure. First of all, a single load case is needed, for example the self-weight of the structure.
Next, the is used.

This generator will automatically generate all the necessary load cases and put them in exclusive load groups. One by one the load cases are generated and can be edited by the user:

The load case manager now shows the following:


It is clear that this new generator provides for a quick and easy input of the wind and snow loads on the construction
