Comparison of concepts between Traditional Seismic Resistant Philosophy and Structural Control Technology




Earthquake-induced energy can only be dissipated by using the nonlinear deformations of beams and columns during earthquakes.

During minor to moderate earthquakes: The safety of the structure may be guaranteed.
During major earthquakes: There are always permanently plastic deformations in the structural members. It is difficult to repair these hazards by using the traditional seismic retrofit alternatives.

The seismic energy can be isolated effectively by using horizontally flexible base isolators.
The earthquake induced energy can be dissipated by using energy absorbers installed in the existing structure.

The safety and capability of a structure during major earthquakes can be guaranteed by using the structural control technology.
