МОДЕЛЮВАННЯ ТА ЧИСЕЛЬНИЙ АНАЛІЗ ЗАЛІЗОБЕТОННИХ БАЛОК ПРИ СИЛОВИХ ТА ВИСОКОТЕМПЕРАТУРНИХ ВПЛИВАХ

Abstract

The results of numerical modeling and calculations according to the developed methods are given. Given the advanced capabilities of ANSYS, this package was chosen for modeling structures in conditions close to fire, and their subsequent calculation by the finite element method. The most promising way to verify the experiment is computer simulation of the structure during a fire, which was performed in ANSYS Workbench. The results of experimental studies and numerical analysis of reinforced concrete beams in the program ANSYS Workbench 17.1. for the first 10-30 minutes are quite significantly different at all control points, but later this difference is stabilized, and until the end of the experiment does not exceed 10.0%, which can be considered quite acceptable. In general, the obtained results confirm that the method of computer modeling with subsequent numerical analysis can be recommended for practical application.
