Woke up early today, just before 6:30am, to go to Yokohama. We toured Taisei Corporation's research center (Taisei is one of the biggest construction companies in Japan).
Afterwards, we went to visit the Landmark Tower which is the tallest building in Japan (296 meters high, 70 stories + 3 penthouse floors, + 3 or more basement floors). So, are you thinking.. Ang low-tech naman ng Japan, sa US may 110+ story-buildings sila, sa China or sa ibang bansa, may mas matataas pa na mga buildings.... Actually, they have a Law here that prohibits the construction of buildings above 300 meters, for aviation purposes! Similarly, Japan doesn't try to produce big airplanes to compete with Boeing, Airbus, etc. But actually, they are involved in their designs!
Anyway, we met one of the structural designers of the Landmark Tower who showed us the 170-ton "vibration absorbers" at the 70th floor. Then we also went to Shin-Yokohama Prince Hotel (~40 stories) where there are water tanks at its top floor that also "absorb" vibration due to wind. If you are an engineer, you might be more familiar with the terms "tuned mass damper" or "tuned liquid damper" or "tuned active damper" or "active mass damper" or "hybrid mass damper."
Going home, I felt so tired, partly because of my "injury" from Saturday pa, so straight home I went and slept quite early today...
