The object of our attention is the designs system of concrete and RC elements (CE and RCE) and structures (CS and RCS), that guarantee their reliability and material economy in different ways. Among those we give the most significant attention to the perfection of ultimate states models. Evaluating using the system analysis methodology [1 – 3], the advancement (development) level of the design systems, recommended by codes of various countries and unions, we can draw a conclusion about insufficiently high development level of these designs systems. Thus, according to the system approach [1 – 3], the advanced system must have connections between the system elements that are well expressed. This implies that there must be connections between certain designs in the design systems. In this context it means not arbitrary designs, but those between which the necessity of connections is quite obvious, for example, between designs correlating as partial and general cases. Nevertheless in all existing codes the non-connected designs are widely utilized, although the existence of actual connections between those is evident.
The strength designs of normal (cross) and inclined (in zone of shear forces action) sections of RCE, recommended in all known codes, are instructive example of noted above demerit. It is obvious that the normal section failure under bending moment M action is the partial case of more general failure case of the inclined section under joint action M, shear Q and sometimes longitudinal N forces. That is way the mentioned designs must be connected in such a way, that from the RCE design under action M and Q the design under action only M ought to follow. Nevertheless the noted codes’ designs are not connected and even quite the opposite: the ones are separated by the methodical precipice which does not allow to obtain the normal section strength design from the design of inclined section.
The source of methodical gap between above mentioned designs is a very imperfect empirical model of the RCE failure under the joint action of the M and Q forces, which is used in various forms in all existing codes. At present a sufficiently workable model of the RCE failure on the inclined crack has been worked out. The strength design of normal section follows from that as a partial case [4, 5, 20]. However this design, in spite of its essential advantages, is not widely known and that is because it demands a higher expertise level of its users, although that level can be built through corresponding teaching program.
In known codes there are many other examples of insufficient development level of the RCE designs system [6, 7]. All of them are evoked by the same causes: dominance of empiricism and insufficient development of the General Theory of RC (GTRC). Here with the empiricism dominance is growing due to information outburst, experienced at present time, that is, in its turn, caused by the complexity of concrete and RC properties. The latter demands increasing number of experimental research, results of which are used first of all in the form of empiric relationships and designs.
The above mentioned difficulties of knowledge development in the field of concrete and RC and designs complication, that takes place at present, may be relieved by means of mastering of general ideas and methods which are inherent for to-day state of science and can be applied to the extensive group of problems [8]. Apparently, this way coincides with the development of the GTRC.
In general, the empiricism dominance is a known indicator of insufficiently high development level of any branch of science. The empirical way of science development is, on one hand, inevitable, however it is also labor- and material- consuming and expensive. On another hand, this way does not always allow to identify all determining factors, influencing properties of structures. These properties of structures cannot be sufficiently optimized and their reliability guaranteed if we apply the empiric approach only. The obtained empiric relations are always partial and restricted by the experiment conditions domain of applicability, which is not always clearly determined.
The transition to the developed scientific theory is possible only as a consequence of an extensive objective process, which involves the accumulation of facts, followed by their generalization in the form of theses, allowing to obtain the mathematical models, describing the considered phenomena. As part of the process, a subjective factor can play an essential role too. By this we mean the ability of users to apply known achievements of fundamental sciences - physics, mathematics, system analysis and their relevant subdivisions. Therefore for working out the scientific theory there is always a substantial knowledge reserve that can be used as a suitable fundamental sciences know-how. In our opinion the mentioned above knowledge reserve of fundamental sciences is insufficiently used in the RCE and RCS designs. This restrains the GTRC development and leads to the empiricism dominance and noted above the disadvantages of known codes’ designs systems.
The stated above situation concerning known RCE and RCS designs systems is the grounding reason for our strategic initiative. As part of our strategic initiative we propose to all interested persons and parties to affiliate with us concerning the following goals:
1. Developing the RCE and RCS designs system, that are more advanced than the known ones, on the basis of our recommendations published in works [4, 5, 9 - 12, 20];
2. Developing International Code of Concrete Structures Projecting, more advanced than the known ones, which includes the earlier developed system of improved designs.
We expect that interested persons will master our two detailed recommendations [4, 12] up to ability to fulfil the practical designs. We are prepared to help by the all accessible to us means to everybody wishing to master the noted works. The outlined works will certainly involve considerable number of organization questions, whose concretization in present is yet premature. However it would be greatly important for us if the interested persons express their opinion about our initiative. Please send your feedback to the E-mail address: vpm.admcs@mail.ru.
