INNOVATION IS OUR DNA
Musi VI Bridge is planned to cross the Musi River in Palembang City, South Sumatera Province, Indonesia. The main span is a steel arch type with 200 m length and side span length is 75 m. Finite element analysis results showed that the bridge has frequency ratio for torsional and heaving mode (torsional frequency/heaving frequency)... Continue Reading →
Ngarai Sianok Bridge consists of 3 main spans, each is 170 m. It also has 2 side spans with 87.5 m long. The two center pylons are 173.6 m tall while the height of other 2 pylons is 91 m. Deck is hybrid type that consists of prestressed box girder part, longitudinal steel stringer, cantilever... Continue Reading →
Flexible bridge is very sensitive with dynamics loading especially in dynamics wind load. Dynamics wind load can make the bridge vibrate with higher amplitude. Some phenomenon in structure failure because of wind dynamics loading is Tacoma narrow bridge which collapsed in 1940 at 18 m/s wind speed and Ferrybridge Power Station which had 114 m...

Wind tunnel test of a sectional model has becoming popular in long span bridge design processes. It is convenient to analyze the bridge deck aeroelastic behavior. The model is simple in structure, hence it can reduce the wind tunnel test cost accordingly, compare to full model. However, the model geometrical shape as well as structural dynamic properties...
