Київ) Сморкалов Д.В., к.т.н., доцент (Киевский национальный университет строительства и архитектуры, г. Киев) Smorkalov D.V., candidate of technical sciences, docent (Kyiv National University of Construction and Architecture, Kyiv) Виконано розрахунок і співставлення прогинів плит, отриманих за допомогою ПК Ліра-Сапр з результатами експериментальних досліджень. Выполнен расчет и сопоставление прогибов плит, полученных с помошью ПК Лира-Сапр c результатами экспериментальных исследований. The calculation and comparison of the stiffness deflection of slabs based on Lira-Sapr (software package) with experimental results.

Currently in Ukraine the use of monolithic structures with post-tensioned ropes, which is better known as the technology of "post-tension", and in domestic construction practice - as post-tensioned reinforced concrete structures with reinforcement tension "on concrete". Ropes are mainly used as tension reinforcement in such constructions. The article presents the main idea of post-tensioned monolithic reinforced concrete structures, presents the experience of using this technology in the construction of public buildings in Ukraine. Such designs have their advantages and scope. Sometimes such designs, in fact, have no other alternative. Therelevance of the study lies in the spread of the use of monolithic structures with post-tensioned ropes, the need to study such structures and the lack of regulatory documents for design. There are also examples of reinforcement of beams and slabs in slab structures and the main advantages of using posttension ropes in monolithic reinforced concretestructures on sites built in Ukraine.

Presented method and results of experimental research of deflection of single-layer and two-layer slabs influenced by short-term lateral load. Proposed method of calculation based on the limit equilibrium method, calculation of slab deflections values by LIRA-CAD bundled software. The comparison of experimental and theoretical results of the calculation of deflections slabs.
