Fire Engineering Design using Mechanical Properties at high Temperature of Structural Steels

To make a new analytic program of evaluation for fire resistance, the backbone of building laws and the technical references related to fire engineering design method were surveyed and the mechanical and thermal data were gathered from the previous experimental data. The analytic program was developed by using the excel utilities and designed 3 major parts; input, solving and output. To verify the developed analytic program the comparison was done by using the previous fire test with standard sized-scale column built with a SS 400. The comparison showed that the increasing of temperature and deformation with time were very similar between analytic results and fire test. But the rapid increase of deformation according to expansion and local buckling caused from higher temperature couldn't be calculated.
