TECHNOLOGY OF MONITORING THE JOIST SLAB USED IN A BUILDING CONSTRUCTED IN THE POLYTECH SYSTEM
Abstract
The paper describes technology of monitoring a joist slab used in a single-family residential building constructed in the Polytech system. Prefabricated units made from a modified mortar based on expanded polystyrene derived from recycling were used to manufacture building walls. The joist slab is based on prefabricated walls, by means of a reinforced concrete tie beam. In order to control the tie beam under realistic conditions, a monitoring technology was suggested that involved introducing fiber Bragg gratings deformation sensors. The big advantage of this measuring system is that this method enables constant measurements of deformations in a construction element during its exploitation. The most important element of the solution is a FBG sensor introduced into the slab structure. The use of measuring method based on sensors with Bragg?s gratings enables constant analysis of operational safety of a given element in the construction phase, during the normal use and loading of the house. During sample loading and unloading, the compound reinforced concrete slab worked in the elastic range. Tests carried out by means of the fiber optic sensor helped to determine the initial imperfection of the slab and its actual deformation.
