Hua Xia Garden
Shanghai, China
The Hua Xia Garden project, located in the southern part of
Shanghai, will consist of three 30-story residential towers over four levels of retail
space over two levels of subterranean parking. The total gross square footage of the
mixed-use development is close to two million square feet with approximately two hundred
thousand square feet of retail space.
A frame and shearwall system was chosen as the lateral load resistant elements for the
towers. A reinforced concrete flat plate system and a more conventional one-way slab
and beam system were proposed for the floor framing system. The latter scheme, more
economical and more consistent with local practice and construction methods, was
selected. Precast prestressed concrete driven piles are utilized as the foundation system.
One structural challenge for the towers was the construction method for the section that
is straddled by the "legs" or "buttresses" of the towers. Four
schemes were proposed. Ultimately, a system using launching trusses at the lowest
high rise floor and cantilever construction similar to that of bridge construction was
selected. A reinforced concrete Vierendeel truss system spans the ten-story middle section
between the buttresses. |
