Experimental and Computer Researches of Ferroconcrete Floor Slabs at High-Temperature Influences

Abstract

The unsatisfactory technical condition of many buildings and structures is due to their aging and requires a quick technical condition assessment. The most promising way for experimental researches data verification is computer modeling of structures, also during a fire. It is advisable to use the ANSYS software. Experimental fire tests of reinforced concrete slabs were carried out. In order to assess the experiment quality and the reliability of the received temperature distribution data, it was used a reinforced concrete slab computer simulation in the ANSYS R.17.1 software system. There was provided a comparative analysis of experimental studies results and numerical data analysis. The results confirm that method of conducted experimental research and computer simulation with further numerical analysis can be recommended for practical application. The mathematical model makes possible operative prediction for the controlled parameters values of building structures.
