Description |
TOWER (Earthquake Analysis and Response of Intake-Outlet Towers) consists of a series of three programs for the earthquake response analysis of intake-outlet towers. The first, TOWERINF, evaluates the added mass associated with the hydrodynamic effect of the water surrounding an infinitely-long, uniform tower. The tower is restricted to cross sections with two axes of symmetry, and the added mass is computed for motion along an axis of symmetry. The second program, TOWERRZ, can be used to analyse axisymmetric towers with hollow circular cross section with radius varying arbitrarily over height, subjected to one or two components of ground motion. The effects of tower-water interaction, due to water surrounding the tower and contained inside the tower, and tower-foundation-soil interaction can be included independently or simultaneously. The third program, TOWER3D, is designed for the analysis of towers with arbitrary cross section but having two axes of symmetry, subjected to one component of ground motion. The outputs from TOWERRZ and TOWER3D consist of the maximum responses-lateral displacements, shear force and bending moment-at selected locations along the height of the tower. |
