摘要:
基于通用有限元软件ABAQUS,建立火灾下混凝土板柱结构的计算模型,采用不同规范中混凝土和钢筋热工参数的取值,对现有试验中的温度场及位移曲线进行模拟分析对比,在此基础上,对实际工程进行模拟分析.分析结果表明:按照美国规范选取材料的热工参数时得到的温度值最高,按照欧洲规范取值时次之,按照中国规范取值时最低;按照中国规范选取材料热工参数和材料力学参数时,模拟的混凝土温度-时间曲线和位移-时间曲线与试验吻合较好;模拟的实际工程呈现冲弯破坏的趋势,与现有试验有所差别.
Abstract:
Based on the general finite element software ABAQUS, the calculation model of concrete slab-column structure under fire was established. The temperature field and displacement curve in the existed test weremidspan simulated and analyzed for the thermal parameters of concrete and reinforcement in different codes, then the actual engineering was also simulated and analyzed. The analysis results show that the temperature value is the highest for the material thermal parameters of the American code, is medium for the parameters of the European code, and is the lowest for the parameters of the Chinese code. When the material thermal parameters and material mechanical parameters are selected according to the Chinese code, the simulated concrete temperature-time curve and displacement-time curve are in good agreement with the test. The simulated engineering tends to the bending failure, which is different from the tests.
