| Zusammenfassung |
| The strength and rigidity of most reinforced concrete (RC) buildings in
Turkey, which are frequently hit by destructive earthquakes, is not at a
sufficient level. Therefore, the result of earthquakes is a significant loss
of life and property. The strengthening method most commonly preferred for
these type of RC buildings is the application of RC infilled walls (shear
walls) in the frame openings of the building. However, since the whole
building has to be emptied and additional heavy costs arise during this type
of strengthening, users prefer not to strengthen their buildings despite the
heavy risk they are exposed to. Therefore, it is necessary to develop
easier-to-apply and more effective methods for the rapid strengthening of
housing and the heavily-used public buildings which cannot be emptied during
the strengthening process (such as hospitals and schools). This study
empirically analyses the different methods of a new system which can meet
this need. In this new system, named "external shear wall application", RC
shear walls are applied on the external surface of the building, along the
frame plane rather than in the building. To this end, 7 test samples in 1/2
and 1/3 geometrical scale were designed to analyse the efficiency of the
strengthening technique where the shear wall leans on the frame from outside
of the building (external shear wall application) and of the strengthening
technique where a specific space is left between the frame and the external
shear wall by using a coupling beam to connect elements (application of
external shear wall with coupling beam). Test results showed that the maximum
lateral load capacity, initial rigidity and energy dissipation behaviours of
the samples strengthened with external shear wall were much better than those
of the bare frames. |
