The State of Theoretical and Experimental Research in the Restoration of Architectural Monuments

Abstract

Currently, in many countries, one of the key areas for improving the efficiency of concrete and reinforced concrete is reducing density by using inexpensive and high-quality local porous fillers. The use of porous filler based on ceramic porite in load-bearing reinforced concrete structures will improve their technical and economic performance and reduce their own weight.

The article presents the data of experimental and theoretical studies obtained in the study of the deformability of prestressed bending elements made of lightweight reinforced concrete with rope reinforcement. The tests were carried out using short-term and non- multiple repeated loads. Based on the analysis of the data obtained, some clarifications were made to the methodology for calculating the deformability of such structures according to current design standards.
