Nonlinear Seismic Design of Industrial Facilities

For the past several years, large scale earthquakes happened. For example, the 2011 off the Pacific coast of Tohoku Earthquake or the Southern Hyogo prefecture earthquake in1995. A lot of industrial facilities such as piping, tanks and cranes were damaged.Nonlinear characteristic such as friction is expected to dissipate the energy of structure excited by earthquake. Therefore, the friction characteristic was utilized in the response spectrum of seismic design, and the nonlinear seismic design was proposed. Proposed design method was evaluated by experiment.
