摘要

为了分析受火后混凝土框架结构的残余力学性能

基于纤维模型的思路

将梁、柱构件截面划分成多个纤维

可以考虑构件截面的不均匀温度场分布以及受火损伤后材料力学性能的变化。以ABAQUS通用有限元软件为开发平台

利用Python编程语言对其进行二次开发

将SAP2000建立的模型文件导入到ABAQUS中

对基于纤维模型的混凝土框架进行受火后的温度场分析和非线性力学分析。通过一个多层多跨三维混凝土框架火灾反应的实例

对该框架在受火后的力学反应进行了分析

可为评估混凝土框架结构受火后的残余力学性能提供参考。

Abstract

In order to analyze the residual mechanical properties of concrete frame structures after fire

a novel numerical model based on fiber model is proposed in this paper.By dividing the cross section of members

such as beams and columns

into many concrete and steel fibers

this model can consider the non-uniform temperature distribution across the section

and also can consider the change of mechanical properties of fire-damaged materials.On the platform of ABAQUS Software

the further development is executed by using of the programming language of Python

and the model files created in SAP2000 Software are imported into ABAQUS.Thermal analysis and nonlinear mechanical analysis of concrete frame after fire based on fiber model are carried out in ABAQUS.A multi-story

multi-span three-dimensional concrete frame after fire is analyzed as an example and the mechanical responses of concrete frame after fire are analyzed.The calculation results provide a useful reference for evaluating the residual mechanical properties of concrete frame after fire.
