Analytical Assessment of the Resistance of Precast Structures to Blast Effects
Terrorist attacks have been carried out on our infrastructure at home and abroad at an alarming rate in the past decade.
This growing threat has emphasized the need for protection of our civil infrastructure from the effects of explosive loading.
Unfortunately both the basic knowledge and expertise on blast resistant design in the US is limited.
While research has been conducted on reinforced concrete (RC) and structural steel, work has been limited in the area of
prestressed/precast concrete. Precast/prestressed concrete offers many advantages in providing blast resistance. The
prestressing properties allow for additional strength and in some cases the potential for a self centering ability after
a blast event. In addition, advanced blast resistant materials can be readily incorporated into precast elements at the plant.
Quantifying these benefits could provide significant support to creating a total precast solution for building construction.
To address this need a research project on blast assessment of precast/prestressed structures is proposed. The research will
analytically examine conventional precast building elements for blast resistance. In addition the potential blast vulnerability
of precast connections will be examined. The fellowship will support the work of one Masters Student for one year. The work
will be conducted in collaboration with High Concrete Structures of Denver, Pa.
