Narrow Reinforced Concrete Slabs after their Flexural Destruction

Abstract:

In the course of the exploitation of building structures frequently situations turn up, in which the structure is not adequately used (it may, for instance, be exposed to considerably greater loads than previously been intended). In the state of an unforeseen overload of the structure, essential reserves of their load-bearing capacity may be disclosed in the case of the self-acting work as a flexible strand. The paper presents the results of investigations concerning the influence of the parameters of reinforcing steel on the mechanism of the destruction of six single-span models of narrow reinforced concrete slabs, in which a horizontal shift of the supports was not possible. The tests were carried out on narrow slabs with the dimensions 3860×480×100 mm. The results of the tests were compared with analytical calculations.
