Detailed commentComentariu detaliat
Validation is primarily a process of comparison of model and its behaviour with the real system and its evolution. Model validation process includes three stages:
The loadings values and the beam length (the spaces on the beam) crucially influences the strength calculus and do not permit generalizations not even in the same constructive type.
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, s_{a}=2000 daN/cm^{2}, f_{a}=0.8 cm).

Overall assessment of the current stage of technical development.Evaluarea generală a stadiului actual de dezvoltare tehnică 
Detailed commentComentariu detaliatA metallic structure, that has a main strength role in the construction assembly, is designed to sustain effective loadings. Mostly, the strains are ignored or a coarse checking is made, based on arbitrary restrictions. Also there are often simplifications made that places us – in strength calculus – far away from the real phenomenon.
It is proposed the strength analysis of a static defined beam for distinguishing the quantitative effect of various simplifying assumptions. It will be researched the neglecting effect of own mass and elasticity (deformability) of supports; it is followed the effect of support idealization and the real mechanical phenomenon of coupling with the rest of the structure remainder.
Mechanical quantification effect of various simplifying assumptions will be made by referring to the main phenomenon which is the mechanical stress produced in the material. The mechanical stress will be correlated with strain; it will be revealed the effect on the material quantity correctly used at building the structure.
For simplifying the following of main loading phenomena, it will be used the beams with circular section, the main phenomenon won’t be customised by this simplification because, initially, the sections are involved by are, inertia moments and axial strength modulus which gives generality to the present study.
For effect quantification of different simplifying assumptions it will be considered as reference model the simple supported beam on an idealrigid structure. The supports will be ideal and will introduce only a reactionforce normal on the beam. The other situations (with own weight, elastic supports etc.) will be referred to this situation considered as a reference one.

What is you overall assessment of the technical feasibility of the research result?Care este evaluarea generală a fezabilităţii tehnice pentru rezultatul CD? 
From the numerical results analysis, there can be observed similar phenomena with the ones previously shown (the general ones), in this way: the own weight has negligible on the necessary material quantity (almost 3% higher); so there can be made calculations with a better precision taking into account only the exterior loadings (concentrated); the own weight must be take into account if there are compactions in supports;
 the stiffening to the supports spinning lead to material saving in a significant quantity, but not a huge one. This fact also recommends studying the consumptions for rigidity before a final conclusion;  the high length of the cantilever imposes its decisive influence, especially in the case of rigidity condition; this fact is mostly shown by ratio ε_{4} that gives the deflection on the cantilever and four times higher than the admissible one (with section from the strength condition). The leading character of the cantilever is also shown by the fact that, if the strength condition is imposed, the section is not influenced by the supports rigidity;  spin rigidity of the supports has negligible influence on the deflection between the supports, but it can decrease de cantilever arrow with significant values (maximum 30%).
As an essential conclusion, generally true for the present study, is the one referred to the structure strains that have a very big importance in structural element strengthmetallic beam. Because the imposed strain leads to great material consumptions, we must not exaggerate in this conditioning; when it is possible, we would the responsibility of the beam maximum loading to be transferred on the mechanic stress conditions (strength ones).
The model is of interest for its implementation in practice, ie its promotion on domestic and foreign markets.
