While a wide ranges of previous researches on rapid construction of super structures are available, the studies on substructures are quite limited. The development of the precast segmental CFDST piers are briefly introduced herein and design formulas are presented for pier segment and Coping, Foundation joints. And present connect method for unit of Precast Bent Cap. The self-assembly Fabricated CFDST column is developed after the pros and cons are supplemented by the Experimental Study with the suggested connecting method.
