The Structural Behaviors of the Corner Columns and Edge Columns in the Experimental Steel Building Subjected to Fire

Abstract

This thesis mainly studied the structural behaviors of the corner-columns and edge- columns made of fire-resistant steel and normal structural steel and under real end-restraint boundary conditions in a full-scale steel experimental building subjected to fire The fire test utilized two adjacent and interconnected compartments (B and D compartments) in the north side of an existing steel experimental building in the outdoor test field of NCKU’s Guiren Campus to test five H-shaped steel columns and the five steel columns were divided into two groups (corner-columns and edge-columns) for experimental results analysis and comparison This thesis also proposed a simplified method which conducted a simple static structural analysis and employed the interaction formula in 2016 ASIC Specification to compute the failure temperature of the steel columns in the fire test The failure temperatures of the steel columns obtained by this simplified method were relatively conservative and this method could save a lot of time when building the structural analysis model and implementing the subsequent numerical calculations It is suitable for general engineers and PEs The analysis results showed that the steel columns with higher axial load ratios at room temperature would have lower failure temperatures in fire and the fire-resistant steel columns had better fire-resistant performances
