Aspects of implementation into practice of the optimization strength theory of RC elements

Abstract

It is noted the tendency toward overcoming of the RC elements designs demerits caused by the increasing designs complication connected with the information outburst and empiricism dominance, which is not always combined with the real designs exactness, optimality and reliability of RC structures. It is emphasized the known direction to the noted demerits overcoming – working out of the General Theory of RC (GTRC) which can be used for solving of the enough wide circle of highly different problems. If the GTRC is accompanied by the simple enough mathematical methods of problem solving, the GTRC mastering by the designers and students turns out more expedient and even easy than totality use of separate particular empiric designs. Therefore it is drawn attention to the earlier worked out the Optimization Strength Theory of RC Elements under joint action of bending moment, shear and longitudinal forces (OSTCE). The OSTCE passed the long and many-sided examination and showed the considerable advantages: Well concordance with experiments, essential economic effect, taking into account some new factors, the general initial fundamentals excepting the necessity of additional empiric relationships, solving method unity for different strength problems, for example, on inclined and cross sections (cracks). For the OSTCE implementation into practice it was worked out the algorithms of optimization problems solving for the strength control and for the selection of needed longitudinal and lateral reinforcement. It is described two recommended design methods: «manual» intended for mastering of the OSTRCE notions and «computer» using simple optimization software for solving of practical problems.
