Abstract
Salah satu bagian dari sarana tranportasi adalah jembatan yang mempunyai manfaat sebagai penghubung antara satu tempat ke tempat lainnya yang melintasi sungai, laut maupun lembah Jembatan Kali Bambang adalah salah satu bagian dari proyek jalan baru Malang-Blitar yang melintasi sungai Kali Bambang dan beberapa lembah di daerah Blitar. Dimana jembatan yang masih dalam tahap pengerjaan ini di desain menggunakan konstruksi PC I girder. Pada tugas akhir ini membahas mengenai modifikasi jembatan Kali Bambang dengan menggunakan Asymetric Cable Stayed dan Prestress Concrete box Girder. Jembatan ini memiliki bentang 175m. Konfigurasi kabel jembatan menggunakan Double Planes System untuk arah melintang dan Semi Harp Pattern untuk arah memanjang. Jembatan memiliki lebar lantai kendaraan 7m, lantai kendaraan didesainlebar agar jembatan tahan terhadap efek aerodinamis.
Adapun hasil dari modifikasi jembatan ini dibatasi hanya pada elemen struktur atas. Dalam pembahasan ini lantai kendaraan didesain berupa box girder pratekan segemntal precast dengan tinggi box 3 m. Sedangankan pylon didesain menggunakan material beton bertulang. Untuk permodelan jembatan menggunakan program bantu MIDAS CIVIL 2011. Pembebanan staging analysis berupa perletakan form traveler akibat beban sendiri dan lantai kendaraan yang diangkat. kemudian jembatan dilakukan analisa gaya dalam akibat sistem balance kantilever. Selanjutnya dilanjutkan perhitungan penulangan box, kontrol lendutan, perhitungan geser, perhitungan dan stabilitas yang meliputi kontrol momen retak, kontrol momen batas, kontrol torsi serta stabilitas aerodinamis yang melupti kontrol terhadap frekwensi alami, efek flutter, dan juga vortex-shedding.

One part of transportation faci
lities is a bridge that has
benefit
s
to
connect one place to another a
cross the river, sea and
valley. Kali
Bambang
Bridge is one
of the new Malang
-
Blitar road
project that crosses Kali Bambang
river
and some valleys in
Blitar
area.
The bridge is still in the
stage of work
and it
is designed
by
using
PC I girder construction.
This
final project discuss about the modification of Kali
Bambang bridge by using Asymetric Cable Stayed and Prestress
Concrete box Girder.
This bridge has a span of 175m and t
he cable
configuration
us
es
Double Planes System for cross direction and
Semi Harp P
attern
for longitudinal direction. The
vehicle
floor
is
7
m
wide and it
is
widely
designed so the bridge is resistant to
aerodynamic effects.
The result of this modification
is
only
in
the upper
structural elements.
V
ehicle
floor
is designed in the form of a box
of prestressed segregnt precast girder with 3 m high.
While the
pylon is designed using reinforced concrete materia
l. For modeling
the bridge uses
MIDAS CIVIL 2011 program. The staging analysis
is in the form of placing tr
aveler form due to
its
own load an
d the
lifted vehicle floor. And then the
bridge
will receive
in
-
depth style
analysis due to cantilever balance system. Furthermore, the
calculation
will include
box reinforcement, deflection control,
shear calculation, cal
culation and stability include control of
cracking moments, boundary moment control, torque control and
aerodynamic stability that control the natural frequency, flutter
effect, and vortex
-
shedding.
