Vpliv požarne zaščite na standardno požarno odpornost jeklenih elementov : diplomska naloga

Hozanović, Samir (author), Hozjan, Tomaž (mentor), Ogrin, Anita (comentor)

V diplomskem delu je obravnavan vpliv požarne zaščite na standardno požarno odpornost jeklenih elementov. Na začetku sta opisana pomen požarne varnosti in obnašanje konstrukcijskega jekla med požarom. Sledi opis različnih tipov požarne zaščite, ki so obravnavani v nadaljnjih izračunih. V četrtem poglavju je predstavljena toplotna analiza, za primer poenostavljenega računa in računa z napredno metodo. V zadnjem poglavju je, na primeru tlačenega stebra s prerezom HEA 240, prikazana razlika v izračunani mehanski odpornosti elementa, ki jo povzroči izbor metode pri toplotni analizi. Poleg stebra, je v mehanski analizi obravnavan tudi upogibni nosilec s prerezom IPE 300, na katerem preverimo vpliv bočne zvrnitve na standardno upogibno nosilnost jeklenega elementa med požarom.

• Title: The effect of fireproofing measures on the standard fire resistance of steel elements : Graduation thesis

Abstract

The thesis starts off with a basic description of fire engineering and the behaviour of structural steel during exposure to high temperatures. This is followed by the third chapter, in which the necessary data for the thermal analysis is presented. In the fourth chapter we take a look at the procedure and results of the simplified and advanced method of thermal analysis. The final chapter shows the difference that the chosen method makes to a column’s ability to bear an axial compression force and the effect of using lateral restraints on the design moment resistance of steel elements during exposure to fire. In addition to the column, in the mechanical analysis, a beam with a cross-section IPE 300 is also considered, in which the influence of the lateral buckling on the standard bending fire resistance is examined.
