In gabled rigid-frame structures, what aspect of the knee joint is highlighted as beneficial?

In gabled rigid-frame structures, the knee joint plays a crucial role in effectively transferring loads and providing stability. The advantage of having greater mass at the knee joint is that it can enhance the overall structural integrity of the building. This increased mass contributes to a greater resistance to lateral forces, such as those caused by wind or seismic activity, helping to maintain the building's balance and stability under various conditions. A more massive knee joint can also help dissipate energy during dynamic loading events, reducing the risk of structural failure.

While flexibility, ease of replacement, or being non-load bearing might offer benefits in different contexts, they do not directly contribute to the enhanced stability and load-bearing capacity that a heavier knee joint provides in a gabled rigid-frame structure. The massiness of the knee joint is therefore a key feature that enhances the structural performance and ensures that the building can withstand the forces it encounters over its lifespan.
