METODA HITUNGAN LENDUTAN PELAT DENGAN MENGGUNAKAN MODULUS REAKSI TANAH DASAR EKIVALEN UNTUK STRUKTUR PELAT FLEKSIBEL
ABSTRACT: To evaluate
deflection of a slab using
theory of beam
on elastic foundation
needs a value
of vertical modulus subgrade reaction (k). This k values
are usually obtained by conducting plate load test using rigid plate with 30 cm
or 76 cm in diameters.
For a larger
concrete slab, the
determination of coefficient
of vertical modulus
subgrade reaction to evaluate the performance of concrete slab
(rigid pavement) need to be examined. A study of the behavior of concrete slab under loading
has been carried
out at the
Soil Mechanics Laboratory
Civil Engineering Department
Gadjah Mada University. Flexible
thin reinforced concrete slabs having a dimension of 3m x 1m x 0,1m, supported by 12 piles have been
subjected to point
loads at several
points. Deflections on the slab
were observed and
compared with those calculated using the theory of beam on elastic foundation
involving determination the coefficient of modulus of subgrade reaction (k).
Results of this
study showed that
the adopted method
may be used
to evaluate the
performance of the concrete slab (rigid pavement) and gave
satisfactory prediction of the concrete slab deflection under a point load.
Keywords: concrete slab,
