ТАМКОВИЧ (Белорусский национальный технический университет, Минск) THE ANALYSIS OF METHODS OF CALCULATION OF STRENGTH OF ELEMENTSFROM THE CONCRETE OF HIGH SPECIFIC WEIGHTWITHOUT THE TRANSVERSE REINFORCEMENT AT IMPACT PUNCTURE/N. RAK, S. TAMKOVICHResults of analize of methods of calculation of strength are presented at impact puncture of slabs from a concrete of high specific weight without a transverse reinforcement. With use of experimental data bank is executed an estimation of accuracy of calculation of size standards of codes of design in territory of Belarus. The index of reliability of the designs, provided at calculation on these size standards of designing is defined. It is shown, that values of an index of reliability depend in the core on a variation of strength of beton. Varia-tions of critical bucklings of elements and armature are reflected in values of an index of reliability slightly. On the basis of the analysis offers on perfection of methods of calculation of reinforced concrete slabs are given at impact puncture.
