| 摘 要： | 本文提出了三结点和四结点平面变截面曲梁单元,按柔度法推导了单元刚度矩阵,并编制了相应的计算机程序。通过算例表明,用这种单元计算如拱、变截面的杆系结构,具有精度高、所需单元少、准备数据工作量小、节省机时的特点,并可应用于某渡槽的计算。

| Abstract: | The three-node and four-node variable cross, section curved beam elements are proposed and their stiffness matrix based on flexibility method are derived. The computer program shows that there are high precision, less element and date, timesaving and other features in the usefulness of the elements above for such as arch and variable section structures. |
