| 摘 要： | 实际工程对膜结构形状的构造提出了各种不同的要求.针对工程中产生的问题,提出了一种膜结构的形状和相对应的自平衡预应力分开确定的构造方法.这种方法使用面力密度法进行节点力平衡的找形分析;然后使用优化的复位平衡法进行找力分析以确定和形面对应的自平衡预应力分布.结合一个具体工程验证了这种构造方法实际应用的可行性和合理性.

| Abstract: | The engineering desires on shape design of membrane structures is multifarious.Aiming at the problem of the engineering,the method which separately determine form and corresponding self-balance prestress of tensility structures is founded.The force method,which is considered surface force density of membrane element,is used to find form of membrane structures.Then,the optimized reposition balance method is used to force-finding analysis and can accurately compute the self-balance prestress of the form.A pro... |
