P. EC8 Stiffness page
Used evaluate whether the stiffness characteristics of the structure meet the recommendations set by EC 8.
Note: The stiffness of
only the vertical elements are considered while working out the total stiffness
of a story in a particular direction as the seismic loads are primarily
resisted by the vertical elements in a structure.
When the Eurocode 8 | Stiffness Checks page is selected, the Floors dialog, Story Stiffness table, and Soft Story table open. The active view window displays the Whole Structure with the Center of Mass and Center of Gravity plotted for each floor. This is used to inform you of some inherent eccentricities and their variation along the height of the building.
