本计算的目的是在设计所给定的载荷(自重、内压、地震、净水压力、接管载荷)条件下,遵照规范规定和设计要求,对装置进行结构屈曲分析,以判定安注箱支承座是否具有抵抗失稳的能力。采用线性屈曲分析,在支承座上端面的节点施加单位载荷,方向向下,约束条件取支撑座底座 The purpose of this calculation is to perform structural buckling analysis of the device in accordance with the specifications and design requirements under the conditions of design load (self-weight, internal pressure, earthquake, clean water pressure, takeover load) Seat has the ability to resist instability. Using linear buckling analysis, the unit load is applied to the node on the upper end of the support, the direction is downward, and the constraint is taken as the support base
