Optimum Aseismic Design of High Steel Piers

摘要

Optimum aseismic design of high steel pier with circular cross-section is presented. The pier is idealdzed by a cantilever with end spring and mass subjected to axial force. The methed of modal analysis and root mean square method are employed to determine earthquake response of the structure. SUMT method is used in the optimum design. N umerical results are shown for the high steel pier which supports two spans continuous truss.
