基于 Python 的梁柱式木结构框架抗火数值模拟系统

摘要

近年来，采用数值模拟手段进行木结构抗火研究取得了较大发展。为了研究自然火灾下梁柱式木结构框架抗火性能，采用 Python 脚本语言将火灾动力学模拟器（FDS）软件和 Abaqus 有限元分析软件集成到统一的平台，编制数据处理、数据存储、炭化深度计算及可视化等模块，建立自然火灾下梁柱式木结构框架数值模拟系统。算例分析结果表明：该系统实现了火灾模拟、有限元模拟一体化分析，较好地反映了自然火灾下梁柱式木结构框架逐步破坏过程。%The numerical simulation method of timber fire resistance has developed greatly.In order to study the fire resistance of post-beam timber frame under real fire,an uniform platform integrated with fire dynamics simulator (FDS ) and Abaqus is developed by Python,and the corresponding system is established with data processing,charring rates and visualization modules.Case analysis demonstrated that thesystem realized the integrationanalysis,and it reflected damage process of post-beam timber frame under real fire.
