Abstract: | The article shows that to determine the torsional stiffness of an element, one should first dissect the reinforcement in the place of an inclined crack. After cutting the reinforcement, the mutual displacement of the crack edges should be determined. This problem is the main and most difficult one in the general problem of determining the torsional stiffness of elements with both normal and inclined cracks. The article is devoted to solving just this most difficult part of the problem – determining the mutual displacement of the sides of an inclined crack of an I-beam element. |
Description: | . Redistribution of efforts between individual elements of complex statically indefinite systems depends on the ratio of their characteristics of rigidity [3, 5, 6, 8]. Flexural stiffness of reinforced concrete elements, taking into account the formation of cracks, nonlinear properties, have been studied quite widely. At the same time, much less attention has been paid to the issues of changing the torsional stiffness of cracked reinforced concrete elements. As a result, in the norms of Ukraine and many countries of the world, there are practically no methods for determining the stiffness and deformability of reinforced concrete elements with cracks. |
