The 356m-high SEG Plaza first began shaking on Tuesday afternoon (May 18), causing an evacuation of people inside while pedestrians looked on in horror run outside building. SEG Plaza is a skyscraper in Shenzhen, Guangdong Province, China. Completed in 2000 and located at the junction of Shennan Road and Huaqiangbei Electronics Market, it stands 356... Continue Reading →
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 →
Wind Resistant Design of Long Span Bridge at Big Indonesian Canyon
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 →
The History of National Laboratory for Aerodynamic, Aeroelastic, and Aeroacoustic Technology
In late seventies, the Indonesian Government planned to bring the country on a higher technology level by establishing high technology industries. Part of this is an aerospace industry with Indonesian designed aircraft. In support of this industry, a wind tunnel is built, it has a 4 m by 3 m with 10 m length test... Continue Reading →
Train accident on Denmark bridge because of wind load
Six people have been killed and 16 others injured in a train accident on a bridge connecting two islands in Denmark, rail operator DSB has said. "We can confirm that six people are dead," a duty officer told AFP, as media reports said the roof of a cargo train blew off in heavy winds and... Continue Reading →
Semi-active tuned mass dampers at Volgograd bridge to suppress vortex induced vibration
On May 20th, 2010, authorities closed the Volgograd Bridge to all motor traffic due to strong oscillations caused by windy conditions. Volgograd Bridge is a concrete girder bridge over the Volga River in the city of Volgograd, Russia. The bridge and adjacent flyovers are 2,514 m long. The bridge, which was inaugurated October 10, 2009... Continue Reading →
Structural and wind monitoring at long span bridge
Long-span bridges are one of the most useful transportation infrastructures to strengthen national unity and to support the development of strategic areas between regions.To ensure safety and comfort for long span bridge, the important technical aspect is the bridge resistance due to wind load. A minor error in bridge construction can impact the whole structure... Continue Reading →
How to Suppress Resonance Induced Vibration at Bridge Structure
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...

Vortex induced at High Rise Building
Wind load on high rise building are very complex, because of many aspects can effects the phenomenon. For instance: shape of the building, terrain around the building, vortex shedding, pressure fluctuation, etc. Wind flow around the building causes the building to oscillate, along wind, cross wind direction, and torsion. Then, vibration on high rise building... Continue Reading →
Wind load on Building
Wind load on building is a complex phenomenon because of the many flow situations arising from the interaction of wind and structures. Wind is composed of a varying sizes of eddies and rotational characteristics carried along in a general stream of air moving relative to eart’s surface. These eddies give wind its gusty or turbulent... Continue Reading →
