How many categories of connections are there in construction?

In construction, understanding the categories of connections is crucial for ensuring structural integrity and overall safety. There are three main categories of connections: rigid connections, flexible connections, and semi-rigid connections.

Rigid connections are designed to resist rotation and provide stability, making them essential in structures where load transfer between elements is critical. Flexible connections allow for some movement, accommodating changes due to temperature variations or other factors, while still maintaining overall structural performance. Semi-rigid connections possess characteristics of both rigid and flexible connections, enabling them to handle specific loading conditions effectively.

Recognizing these categories helps engineers and builders select the appropriate connection types for different scenarios, enhancing both the efficiency and safety of construction projects.
