施加杆件单元预应力荷载时，竟然没找到从哪输入的。v8版本在“指定”里能找到prestress,在v9版本里没找到啊。正是入门阶段，各位指教了，谢谢！

自己回答吧！
Click the Draw menu > Frame/Cable/Tendons command to display the “Properties of Object ”form. In that form,
Click the “Line Object Type ”drop-down list and select the “Tendon ”option.
Click on the joint at one end of the beam and then click on the joint at the other end of the beam to draw the tendon. The“ Tendon Data for Line Object 2” form will display when you release the mouse button.
这样就可以编辑输入预应力荷载了
