Concrete Journal, Vol.44, No.4, Apr. 2006


Synopsis
The authors developed an underground water tank of precast concrete for avoiding floods by rain water outflowing. This water tank have few features: roof constructed with prestressed concrete, and each columns' span of 10 meters that is more than twice as long as a water tank constructed with usual reinforced concrete. Therefore, long span of each columns enables to build an economical and efficient institution. Long span of each columns and flat bottom slab enable to maintain an institution easily, and to clean by heavy industrial machines. Moreover, precast concrete method of construction enable to shorten terms of works on building site. The authors developed a pin joint method for junction of precast concrete members which bears an earthquake of level 2, and examined its method performance by an actual size experiment.
