摘要:
为了简化深肋组合扁梁理论计算模型,同时对中国现有的深肋压型钢板板型进行改进,通过有限元软件ANSYS对深肋组合扁梁的正、负弯矩区进行有限元分析,并利用现有的试验结果进行验证分析,得知深肋组合扁梁肋部混凝土在梁受力全过程中应变均很小,承担的荷载很小,因此在受力上可以忽略; 同时揭示了深肋组合扁梁的部分受力特点,为深肋压型钢板选型提供力学参考。结果表明:在对深肋组合扁梁进行理论计算时可以忽略肋部混凝土的影响,同时在满足楼板承载力和构造要求下,可以进一步改进深肋压型钢板板型,减轻质量。
Abstract:
In order to simplify theoretical analysis model of composite slim beam with deep deck and improve the shape of deck in China at present, and through ANSYS software, finite element analysis(FEA)was used in the positive and negative moment zone. The conclusions that concrete in the deep deck was distributed little load and its stress was low were got, also an experimental result was dealt with. Parts of the stress characteristics were gained, which afforded proof to select the type of the deep deck and improved the shape of the deck. The results show that the concrete in deep deck will be neglected in theoretical analysis and the dimension of the deep deck will be ameliorated to reduce the amount of concrete in slim beam.
