|To a point
||Specify the coordinates in current length units of the point to which one of the ends of the member are to be moved. The point must lie on the axis of the member being stretched, or else, the stretching will not be performed. The program automatically determines which of the two ends of the member is to be moved. So, this method involves
- determining if the point lies on the axis of the member(s) being stretched
- determining which end to move for the member(s) which satisfy criteria (i)
- replacing the corresponding nodal coordinates with those of the desired point
|Through a distance
Specify whether the start or end node will be stretched and the distance by which to stretch this end. In this method, all members selected for this operation will see the change in length.
You must create a node a resulting intersection point separately using the Intersect Beams tool.
|To an existing node
This is very similar to the To a point method. The only difference is that instead of explicitly specifying the coordinates of the desired point, that point is already available for identification through its node number.
A list of all nodes in the model is available in the drop-down list. Alternately, click the Node selection tool to select a node graphically.
|To an existing member
If two members lie within a plane, this method may be used to stretch the first member to meet the second member. The second member will be automatically split at the intersection point into two segments.
A list of all members in the model is available in the drop-down list. Alternately, click the Member selection tool to select a member graphically.
