Upon reading the manual of Wave Response, it suggests that it calculates equivalent static load in order to solve directly (section 1.2). How is this type of analysis different from a normal static conventional analysis ?
1) Stiffness of the structure remains same as that of a standard Stiffness Analysis (static) ?
2) DAF for the structure automatically gets involved in this equivalent static Load ?
3) PILSUP command requires input of Load cases to calculate pile stiffness in Global X or Y Direction. Stiffness of Pile is intrinsic and dependent upon Soil Properties & Pile Geometry. How do load cases determine the stiffness ? Should the load cases entered be the environmental condition or Dead Load ?
