A variety of seismic response modification technologies are effectively used to mitigate damage of urban infrastructures during a significant earthquake. Seismic isolation is widely adopted for bridges. Isolation of underground structures from the surrounding soft soils is often used to mitigate the response. Various damper technologies are used in not only standard bridges but also long-span bridges. Rocking isolation is attracting increased interest. Emphasis of this lecture will be placed on the seismic design of transportation facilities including bridges and underground structures in soft soil deposits. The target of the seismic response modification of bridges and underground structures is not to secure the comfort of residence during small to moderate earthquakes as buildings but to enhance the seismic performance during a significant earthquake. Presented in this lecture are passive and semi-active damper technologies, variable dampers, advanced magnetic rheological damper, seismic isolation using elastomeric bearings including the lead rubber bearings and the high damping rubber bearings, effect of pounding of decks, rocking response isolation of foundations, isolation of underground structures, and implementation of seismic isolation to seismic retrofit of existing bridges.
