Direct Method

Definition

The direct method refers to an approach used in engineering, particularly in assessing soil-structure interaction and conducting advanced numerical modeling. This method directly evaluates the effects of soil on structures by considering the physical properties and behavior of both the soil and the structure, leading to a more accurate analysis of their interaction during events like earthquakes.
