is a parameter used to adjust the contribution of an object's own weight in structural analysis. This factor is particularly useful in simulations, as it enables the scaling or modification of the self-weight during finite element analysis (FEA). Stiffness [Yes/No]: During staged construction analysis, bridge owners typically choose not to consider the stiffness of the barriers to be conservative and only take their weight into account. |

However, when applying wind loads, the elements must be constructed with their stiffness. If wind load application is required for the project, the concrete material must be duplicated and assigned a small modulus of elasticity (e.g., 1) to construct the element with its stiffness. Using a small modulus of elasticity(stiffness) value will create the expected behavior.
