|Since the technical field is using a high variety of strength structures, studying their behavior is achieved by using numerical models that have common features for a high number of structures.
Adopting numerical model for a certain strength structure is done based on simplifying assumptions, which should not introduce large errors and must comply with the basic features of strength structure.
Having adopted the numerical model of the structure, mathematical equations can be developed to describe both the physical model and the behavior of the structure, when it is stressed by a certain load.
The evaluated measured number enables a correct simulation whereby the errors are minimal.

|The need to correlate power with rigidity for a metal structure is resulting from the following key aspects regarding the current state of play and development trends:
- Lack of numerical models as close in terms of structure and behavior with real models for metal structures;
- The entire process of research and testing to be performed entirely using computer media.
The supports rigidity has a big importance. The additional displacements support producing additional high loadings that impose higher sections. This thing recommends discharging of disallowed displacements (later functioning uncontrolled compaction).
The support stiffening makes the beam loading to decrease, leading to section decrease (material saving). Extra, the rigidity condition leads to section dimensions closer to the ones given by the strength condition. Material saving must not be taken “straight meaning” because the stiffening involve additional materials usage that diminishes the positive effect; nevertheless it must be underlined that the stiffening on the supports are a solution of increasing the beams strength, the more so as the stiffening solution are more rational and do not lead to sections increasing of adjacent structure elements.
Those stated before are sustained with numerically values by applying to the calculus model defined for a real constructive solution (F=4000 daN, Q=2000 daN, a=b=c=200 cm, sa=2000 daN/cm2, fa=0.8 cm).
The project’s innovative character stems from the fact that highly performance software products can be launched on domestic and European markets.
|What is the potential for further research?Care este potenţialul pentru cercetarea viitoare?|
|Scientifically and technically, it is required to develop numerical models for the correlation strength & rigidity for a steel structure.The research result is included among research directions on computerized calculations of strength for metal structures.
The main goal of research result is to develop mathematical models for solving problems of structural strength of metal structures.
The research team of Applied Mechanics Department of the Faculty of Mechanical Engineering, University of Craiova, has a long experience in both research and the following:

- Clearly indicating the computer program;
- Laying down the marketing terms (price, quantity).
- Know-how: a set of non-patented practical information, resulting from experience and testing, which is secret (ie not generally known and not easily accessible).
|What is you overall assessment of the scientific maturity of the research result?Care este evaluarea generală a maturităţii ştiinţifice a rezultatului CD?|
|Developing of a set of original knowledge aimed at the correlation strength & rigidity for a metal frame is a proof of scientific maturity of the R&D result. Scientific and technological excellence of research result consist of:
- Optimization of mechanical structures based on mathematical models;
- Fidelity of computer simulations depends on accuracy of mathematical models used and the way they are assembled.
The accomplished study, especially in the private case, allows pointing many mechanical phenomena issues of loading that have general application and are useful for the metallic structures designer. The study conclusions, which we consider that have implications with general aspect or crucially influence the designing conception will be presented below.
First of all, it can be said that imposing a rigidity condition leads, mostly, to higher dimensions than the ones obtained from the strength condition. This fact is known and that’s why it is proceeded to strength structure conditioning with some corrections from strain checking.
The current state of play of knowledge, theoretical approaches and practical implementations reveal that the solutions presented are real and feasible.
