Which of the following is considered a disadvantage of using roller connections?

The correct choice underscores a significant characteristic of roller connections, which is their ability to permit horizontal movement. This feature makes them particularly valuable in construction and structural applications where flexibility is needed to accommodate thermal expansion, contraction, and other types of lateral forces without inducing stresses that could lead to structural failure.

By allowing horizontal movement, roller connections are designed to accommodate the natural movement that can occur in structures due to various environmental conditions. In scenarios like seismic activity or thermal changes, this movement alleviates stress on connected components and provides a level of adaptability that rigid connections do not offer.

The other considerations, while factual, do not pertain directly to the specific disadvantages posed by roller connections. For example, while roller connections can handle different load types, they inherently lack the ability to resist vertical forces, which could be viewed as a disadvantage in some contexts. The requirement for a larger base is also a more practical construction concern rather than a disadvantage, as it may depend on design specifications. However, the primary advantageous trait of roller connections remains their ability to allow movement, which is critical for addressing dynamic loads effectively.
