当排烟冷却塔采用烟道高位进塔方案时,为了满足烟道运输要求,需要不均匀布置人字柱,破坏了环基的对称性,造成其受力状态改变.利用有限元软件ANSYS对该冷却塔在风荷载作用下的受力状况进行分析.计算结果表明,此时环形基础的内力分布规律不变,但其极值与风荷载的方向有关,存在使环基内力最大的风向角;在该风荷载作用下,环基内力的最大值出现在最大跨附近,需要加强此处配筋.
When the flue gas cooling tower adopts the high-flue tower approach, in order to meet the requirements of flue transportation, it is necessary to arrange the studs unevenly, which destroys the symmetry of the ring foundation and changes the stress state of the ring foundation. Using finite element software ANSYS The cooling tower under wind load analysis of the state of force.The results show that the annular foundation at this time the internal force distribution of the same, but the extreme value and the direction of the wind load, the existence of the maximum internal force of the ring-based wind direction angle ; Under the action of wind load, the maximum value of the internal force of the ring appears near the maximum span and the reinforcement needs to be strengthened here.
