Are you using link elements as they were intended?
Most of the structures need links for accurate force transfer. It may be used to
rigidly transfer force like in the case of a pile cap or it may be used to introduce
certain flexibility in structures, like in the case of a bridge bearing. However,
using the right type of link elements is particularly important for correct structural
behavior.
Through this eBook, you can learn about the different types of link options
available in midas Civil. Illustrative examples are provided to help you
understand what type of link elements could be used in a specific scenario. Common
mistakes while modeling links and how to avoid these have also been discussed.
Key Points

01-1. Elastic Link
01-1-1. Elastic link - General
01-1-2. Elastic link - Rigid
01-1-3. Elastic link - Compression Only
01-1-4. Elastic link - Tension Only
01-1-5. Elastic link - Multi-linear
01-2. Rigid Links
01-3. General Links
2. Differences Between Link Elements
02-1. Rigid Link vs. Elastic Link - Rigid
02-2. General Link vs. Elastic Link - Rigid
02-3. General Link vs. Elastic Link - Multi-linear
3. Link Application Examples
Case 1. Box girder superstructure up to the bottom of bearing
Case 2. Connecting pier to foundation plate elements
Case 3. Modeling a pylon with a continuous cable for an extradosed bridge
4. Common Mistakes in Modeling Link Elements
04-1. Activating the connected nodes without activating the link
04-2. Activating links without activating the required nodes
04-3. Incorrect modeling with rigid link links
