ANALISA RESPON STRUKTUR MENARA PEMANCAR TIPE “M ONOPOLE “ 120 m AKIBAT BEBAN ANGIN RENCANA DENGAN PERIODE ULANG 10 TAHUNAN DI STASIUN BADAN METEOROLOGI DAN GEOFISIKA SEMARANG
ABSTRACT: Tower is
one of the
facility to support
signal which is
influenced by the
elevation factor. For
a tower at
high elevation, the influence of wind will be very significant to the
structure. Therefore, wind site survey should be conducted prior to tower
design. The type of tower considered is tapered monopole of 120 m high
constructed at Meteorology and Geophysics Station, Semarang. The measurement of
anemometer and data analysis resulting in wind velocity of 10-year return
period. It was obtained that the maximum
wind velocity was 100.8 km/hour or equivalent to 28 m/sec and this will the input
for the following
analysis. The upper structure
analysis is carried out
with the help
of MsTower which
is referred to EIA/TIA-F and LRFD concept.
With input of
maximum velocity obtained
from survey, the
tower was analyzed
for internal forces.
The axial forces
is 115.0466 ton and moment about x-axis of 16.00 ton-m.
