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 |

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 |

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. |
