Abstract:
In the middle of January 2006, a very large settlement of the south-eastern corner
of a residential building in the southern part of Tel Aviv occurred which resulted
in considerable inclination of the building.
Because of the danger that the whole
building will collapse, a part of the building has been demolished.
The
foundations of the building, constructed at 1962, were concrete piles cast in clay.
The failure of the foundations was the direct reason for the sinking and
inclination of the building.
The bearing capacities of the piles were lower than
the design loads, but despite this the building survived for more than 40 years.
This presentation will include: location of the buildings; description of the
structure; the foundations; the topographic and land-use changes; the reduction
of soil capacity and failure details.
Keywords:
residential building, structure, foundations, pile, topography, soil
capacity, reduction, sinking, inclination, failure, demolish.
1 Introduction:
The accelerated urban development and the extensive construction works that
took place in Israel during the second half of the 20th century, brought to a vast
change in land use and, as a result, a severe deterioration of the hydrological and
mechanical soil status.
Wide areas that were traditionally used as an agricultural
land turned into large cities with residential spaces and other accompanied
infrastructure like railways highways and industrial zones.
Without a careful
design, changes in topography and intensive excavation causing brutal violation
of the natural equilibrium.
In the following case, rapid, non-standard
construction of condominiums in the southern part of Tel Aviv brought to a
