| 摘 要： | 储罐除了受自重、液体内压作用外，还受到风荷载的作用，从而在储罐中产生应力，应力过大会引起储罐的损坏。提出风载荷作用下圆柱形储罐分析的位移有限元法，根据圆柱形储罐属于轴对称壳体这一结构特点，用圆柱壳单元和圆环壳单元将其离散化，单元之间以结点圆相连接，风载荷和位移沿环向展开成三角级数，降低了计算维数，减少了计算工作量。用编制的有限元分析程序对一个算例的计算表明，该方法能方便有效地计算风载荷工作下圆柱形

| Abstract: | Storage tank will be affected by wind load besides the action of dead weight and internal hydraulic pressure, which will generate a stress in storage tank and over stress will lead to its damage. The article puts forward a displacing finite element method for cylindrical storage tank analysis under wind load action. According to its structure feature that cylindrical storage tank belongs to axial symmetry casing body, discrete it to cylindrical casing unit and annular casing unit > with nodal point circle connected between each unit, wind load and displacement will spread along the circle into a trigonometric series, thus reduces calculating dimension, working load and time. It is shown with an arithmetic example calculated with a programmed finite element analysis program, the method can be used to calculate a stress on cylindrical storage tanks conveniently and effectively. It provides a theoretical basis for design of cylindrical storage tanks. |
