Analysis of Structural Stability for H-Section Made of SM 400 According to Lengths and Boundary Conditions at High Temperatures

Abstract:

A fire can cause serious damage to steel framed buildings so most of countries have fire regulations specifying fire resistance for structural elements. Fire resistance generally has been evaluated by a limited size testing facility. However, the size of columns and beams are different based on various conditions. Especially, the height of column and boundary condition are the main factors that govern the fire resistance of structural elements. To make a basic database for the H-section made of an ordinary grade structural steel, SM 400, an analysis was conducted by using mechanical and thermal properties with a proper theory. The fact findings suggested that the fire resistance for longer and fixed to fixed column were required a new guide line for covering of fire protective materials.
