Abstract

Abstract Herein will be presented a study on the use of parameter γz for reinforced concrete frames in fire situation. Currently, there are no results of similar research for concrete structures, since the subject has not received the adequate attention. In fire situation, many of the horizontal actions are no longer considered in exceptional load combination, leaving only the horizontal action due to the global geometric imperfections. Once the equivalent horizontal forces to these imperfections are obtained, the parameter is applied. One of the conclusions was that the parameter γz is not adequate, in particularly for high buildings, indicating that more research is necessary. Even so, using γz for room temperature, we conclude that fires that affect lower floors are more damaging to the building and more floors under fire also lead to worse results. (AU)
