摘要:

In this paper, a fire simulation based numerical method analyzing frame structures in a real fire is proposed employing zone model (CFAST) to simulate the fire growing and the temperature distributions in a firing room. Two computer programs are developed to predict the behaviors of the structures in a fire environment, one for thermal response simulation, and another for structural analysis. The finite element thermal program is achieved by using a mixture of finite element and finite difference methods and transmission of the thermal environment to the structure analysis program is reached through linking the elements to the results of the CFD model. The structural analysis program contains a fiber beam element and a layered shell element that can be used to predict the tensile membrane behavior of slabs in fire conditions. Both programs have been validated against data from experimental tests on a reinforced concrete slab and a reinforced concrete frame. Furthermore, by using the PCL language provided by MSC/PATRAN and Fortran language, a system for analyzing the overall behavior of structures under fire is developed on MSC/PATRAN platform. The behavior of building structures under fire can be simulated with this system and the results can be used as the reference for the fire safety analysis and assessment of general building structures under fire.
