Light steel framed walls made with composite panels under fire conditions
| Resumo: | Light steel frames (LSF) using prefabricated panels are widely used in partition walls and loadbearing walls, with direct application in different types of building structures. These panels can be made by a combination of materials, which is the case presented herein. Some of the materials can be combustible, being the prediction of the fire resistance by means of numerical simulation difficult. Walls that meet fire resistance standards are the result of the proper combination of certain materials and elements. These materials and elements should be experimentally tested, allowing the wall to be fire rated. Three dimensional finite element models are validated, including the simulation of all the major events (combustion and cracking of materials). The fire resistance is determined for different LSF walls and decreases with the load level. A new formula is presented for the average critical temperature of the LSF structure. |
