【摘要】：结合可靠性理论与BIM技术,分析建筑风环境的随机特征,导出流体介质随机控制方程,采用小参数方法建立随机有限元模型。考虑风环境的随机性,分析超越概率风环境评价指标,提出建筑园区可视化BIM建模步骤。在此基础上,提出风环境舒适可靠度的概念,导出舒适可靠度计算公式。依据BIM模型与建筑规范标准,建立建筑风环境BIM模拟与可靠性评价方法。研究结果表明:该方法对建筑风环境随机影响分析更加符合工程实际,对建筑风环境评价与设计具有应用价值。
[Abstract]:Combined with reliability theory and BIM technique, the stochastic characteristics of building wind environment are analyzed, the stochastic control equation of fluid medium is derived, and the stochastic finite element model is established by using small parameter method. The randomness of wind environment is considered. Based on the analysis of the beyond probabilistic wind environment evaluation index and the steps of visual BIM modeling for building parks, the concept of wind environment comfort reliability is put forward, and the formula for calculating comfort reliability is derived. According to the BIM model and the building code standard, the calculation formula of comfort reliability is derived. The method of BIM simulation and reliability evaluation for building wind environment is established. The results show that the method is more in line with engineering practice and has application value to wind environment evaluation and design.
