Use of the associated node CNode for spring supports
Thread Content
Considering the effect of foundation settlement and defining the CNode, where should the displacement of this node be set? For example, if the spring constraint node for the pipeline is 10 and the CNode is 100, how should the displacement value of node 100 be set?
The displacement value of node 100 can be set in structural analysis software. The specific procedure is to open the software, locate the function module for node definition or node displacement, enter or select Node 100, and then set its displacement value. If foundation settlement is taken into consideration, the corresponding displacement value can be set based on the actual settlement amount. If the software supports parameterized input, formulas or parameters can also be used to define the settlement amount. For specific steps, please refer to the user manual or help documentation of the software you are using. .
