We look back to some of our own tube in tube construction, actually the first concrete tube structure here in Chicago 1965, The Chestnut Dewitt Apartments. You can see the first time, where that load bearing wall was the primary structure. And the building looks great today with these beautifully proportioned Windows within, a tab that stood the test of time. Buildings like One Shell Plaza in Houston, where the concrete tube is actually transformed and reflects the structural forces at play here. You can see a floor plan, where in the depth of the primary structural elements, those little colonists are increasing where the forces are being transferred from the core itself. That becomes a key aspect of the building's expression. Its neighbor across the street, the sibling to Shell Plaza, has a different take, where the concrete is sort of deposited if you will, at the lower portions of the building in this beautiful gradient that expresses the structural forces as they come down and open up to create a ground floor arcade. Another example in Chicago, the Brunswick Building, where the piano noble above the lobby is used as a structural beam or lintel to make that transfer. So you can see that we have many different approaches. The Burj Khalifa, many people don't realize is concrete itself. We were not averse to it and embraced this problem if you will.
So if you use some common sense and plan out your route carefully, you can have a bridge adventure you will never forget. Just remember that sudden setbacks will come up. Bad weather can come at anytime. Cars, buses and trains break down. Also remember that the advice I have given to you is no substitute for all of the normal, travel related things that you would have to prepare for on any big trip to China that are mentioned in such guidebooks as Lonely Planet or Fodors. The process of obtaining travel insurance, visas, permits and vaccinations are all well described in these books and beyond the scope of this website. Since I have traveled to western China several times, I do have some good contacts with drivers who have visited some of these high bridges and are trustworthy. If you are planning a bridge trip to western China, I will be glad to give you any advice and suggestions.
The residents of Tunpu successfully supply the farming technology of plains in the east areas of Asia to karst mountain areas, creating the unique rural scenery which reflects the harmonious relationship with the land, water and biology in karst mountain areas.
