Scope

Scope: This standard applies to the evaluation of the seismic performance of in-service concrete beam bridges with a single span not exceeding 150m in areas where the peak acceleration of the basic earthquake motion is no greater than 0.4g (corresponding to the seismic intensity IX zone). Suspension bridges, cable-stayed bridges, arch bridges, and special complex bridges can be evaluated in accordance with the principles of this standard. Main technical content: This standard is divided into seven chapters and two appendices. The main technical content includes 1 General Principles, 2 Terms and Symbols, 3 Basic Provisions, 4 Ductility Capacity Enhancement, 5 Seismic Isolation Capacity Enhancement, 6 Energy Dissipation and Seismic Isolation Capacity Enhancement, and 7 Seismic Measures Enhancement. Appendix A provides an analysis method for energy dissipation devices, and Appendix B provides a calculation method for the additional stiffness and damping of energy dissipation devices.
