Recent research in the field of
(NSF Award No:
gave rise to a non-commercial release of innovative software called
Earthquake Performance Evaluation Tool
EPET enables experiments with a virtual building on
accompanied with simultaneous virtual testing of the identical but fixed-base building.
On users' demand, all those concurrent experiments may be animated.
As a continuation of the previous research, this educational Internet site is meant to
facilitate potential users' performance and expand the variety of buildings, earthquake
exposure and types of
devices. The project, abbreviated as EPETO, has had the following stages:
Modify EPET to describe a building model deformation in two orthogonal horizontal
directions while an earthquake input in those directions is not, necessarily, the same.
Provide 3-D animation of a seismic loading, use five colors to depict the basic
damage categories of the building and visualize its damage or collapse.
In addition to the sliding base isolators like, for example, Earthquake protector, provide
ability to evaluate the earthquake-protective effect of other types of
In addition to different types of base isolators, provide ability to evaluate the
earthquake-protective effect of
installed in a building superstructure.
