Concrete Framed Buildings
This is a quarter scale model of part of the
structural frame of a 4 storey
building constructed in reinforced
concrete. The frame is strengthened by bracing
members with metallic dampers
at their bottom ends. This system was designed to strengthen
buildings that have already been built, but that are not strong
enough to resist earthquakes in their area.
Two versions of this model were tested for simulated earthquakes
on the shaking-table, one with the bracing
system and one without. This way the strengthening effect
of the system could be investigated. The deformation
and movement of the models were measured, and the degree of
damage to each one was recorded.
