We will consistently conduct the verification of the lower limit of horizontal load capacity for steel bridge piers and dynamic seismic design.
The seismic design support program for steel bridge piers, 'JT-SPIER', is based on the Road Bridge Design Guidelines and Commentary I Common Edition, II Steel Bridges and Steel Members Edition, and V Seismic Design Edition (November 2017). It supports the verification of the lower limit of horizontal load capacity for standalone steel bridge piers and dynamic seismic design. It accurately performs nonlinear dynamic analysis using the M-φ model or fiber model and can output the verification results in a calculation report style.
