Abstract
The FAPESP Thematic Project 2006 / 06742-5, entitled "Safety of Structures in Fire Situation", allowed the acquisition of a horizontal furnace, at the time the first in the national territory capable of carrying out, on a natural scale, temperature tests of loaded specimens, what is presented in Appendix A. Such equipment is currently in operation in the Department of Structural Engineering of EESC / USP. The present research project aims to extend the study of the resistant capacity of structures in fire situation by means of numerical and experimental analyzes using the aforementioned furnace and other existing furnaces, located at the Faculty of Civil Engineering of UNICAMPThus, the present proposal is based on numerical and experimental analyzes of simplified models of concrete blockwork masonry, subjected to high temperatures, aiming to study the behavior of this construction system exposed to the thermal action caused by fire. Initially, national and foreign normative procedures will be analyzed and discussed, as well as the design models considered in each normative document. Experiments with small walls, prisms and blocks, submitted to compression in a fire situation, are predicted for validation, considering future adjustments to the physical and mechanical conditions of the Brazilian structural masonry, and models currently employed by the international technical / scientific community. Besides the experimental analyzes, numerical models will also be developed to simulate the behavior of structural masonry exposed to fire.As a main contribution, it is expected that the obtained results, as a novelty in Brazil, will result in subsidies to the normalization, since there is still no standardized procedure for structural masonry design in fire situation in national codes. Additionally, the gain of experience of the researchers involved in the research is also considered.. (AU)
