Large ornate cornices on a structure are an example of what type of load?

Large ornate cornices on a structure are considered an eccentric load because they extend beyond the wall or supporting structure, creating a load that is not applied directly downward through the center of the supporting structure. An eccentric load is positioned unevenly, leading to bending moments that can affect the stability of the structure.

When the cornice varies in weight and is supported only at one side, the distribution of the load can result in additional stress on the supporting elements, which is a key characteristic of eccentric loading. Understanding this concept is crucial for assessing potential issues in structural integrity, especially when fire tactics involve considering the load-bearing capacities of a building during an emergency situation.

In contrast, static, concentrated, and balanced loads refer to different methods and distributions of load application, but they do not encapsulate the unique stresses associated with elements that protrude from the structural line, like cornices.
