[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.
