From May 11th to 13th, everyone at TESolution went on a company trip to Jeju-Island, a volcanic island and also Unesco Heritage site located south of the Korean peninsula famous for its beautiful scenery of grass covered volcanic lava cones and beaches. It was a great time for all of us to briefly forget about the Covid-19 situation that has globally impacted the way people go about their everyday business and enjoy the moment and breathe in fresh air.
Special thanks to our CEO Dr. Kim for this unforgettable experience.
Workshop testing for Tuned Mass Dampers for Kobe Steel Chimney was completed at TESolution structural lab in Korea and they were safely packed for shipping on the first week of May. Kobe Steel Chimney is located in Kakogawa, Hyogo Prefecture, Japan. It is a very slender and flexible structure so its structural stability is often determined by wind load rather than earthquake load.
In particular, in this type of structure, the structure system is often determined by the vibration in across wind direction rather than the vibration in along wind direction,
In order to avoid potential risk of vortex induced vibration and aerodynamic instability within the designed wind speed range 4 sets of 0.76ton TMD were designed to be installed at the top (90m) of the structure where the maximum deformation is expected.
Workshop testing for Tuned Mass Dampers for the Greenland Centre Sydney residential tower was completed at TESolution structural lab in Korea last April. 180 ton moving mass is designed to slide back and forth on top of the Linear Motion Guides while most of its vertical load is dispersed throughout 4 rubber bearing columns that can freely move horizontally as shown on the above pictures.
The TMD is on its way to Sydney at the moment, and it will be installed on the top floor of the tower somewhere in this up coming summer.
The design of TMD utilizing rubber bearing column is very unique as it can be tuned to the structure with extremely low natural frequency while maintaining relative low vertical installation space as opposed to traditional pendulum type TMDs.
Witness Testing of Mythuan No.2 Bridge in Vietnam took place on September 18th.
The engineers and the government officers from TEDI, PMU7, and Ministry of Transportation(MOT), Vietnam have visited TESolution wind tunnel facilities and witnessed the wind tunnel testing on Mythuan No.2 Bridge.
Now that Taichung Treasure Graden 150 ton TMD, located in the city of Taichung Taiwan, is nearing its Completion, we can finally see the beautiful bi-directional Pendulum TMD in its entirety, including the buffer system as well as four massive hydraulic dampers hanging from the ceiling.
On May 3rd, 2019, there was a signing of the contract for Wind Tunnel Testing of My Thuan 2nd Bridge in Vietnam between Dr. Kim, CEO of TESolution, and Mr. Son, the General Director of TEDI(Transport Engineering Design Inc) at TEDI's office in Hanoi.
It was a wonderful time for us to introduce our company as well as our products and service we offer in the field of wind engineering such as our wind tunnel testing facilities and track record, Tuned Mass Damper, and Active Mass Damper for various buildings and civil structures.
Once a state owned public company, TEDI has turned to private company in 2014, and now is the biggest civil engineering firm in Vietnam.
TESolution is grateful for everyone at TEDI who had attended the meeting as they have been an enthusiastic audience during our presentation, with special thanks to Mr. Son, the General Director and Mr. Dung, the Deputy General Director of TEDI who have provided us with this great new business opportunity in Vietnam.
TESolution has designed the vertical TMD to control the vibration of the main girder of the Haneda Bridge in Tokyo Japan and produced a TMD prototype for testing at TESoluion Structural Lab.
This time TESolution engineers visited the workshop in Japan to inspect the fabrication procedure of TMD as well as to test the damping performance of oil damper as well as TESolution designed silicon damper.
TESolution has installed its first bi-directional Pendulum TMD on top of the Taichung Treasure Garden residential high rise in the city of Taichung, Taiwan.
The installation procedure has been divided into several steps and TESolution engineers have installed the oil dampers, the tuning jigs as well as the buffer system on 150 ton pendulum TMD mass supported 6 cables during this installation trip.
We still have one last trip left to work site during which TESolution engineers will commission the TMD system. Can't wait to see the whole system after completion.
TESolution has won the supply of Tuned Mass Damper for the Greenland Centre Sydney in Australia.
Greenland Centre wil be located on the corner of Bathurst and Pitt Streets in the heart of Sydney CBD and with the height of 235m, it will make the tallest residential building in the city once built!
TESolution has participated in CWE 2018, held in Seoul, Korea as an Exhibitor and attracted number of visitors from various academic institutions.
Our miniature AMD model originally designed for CTBUH 2017 Sydney was on display again to show its effectiveness in controlling wind vibration to the visitors.
