Constructibility Problems in Blast Resistant, Reinforced Concrete Structures
Design of reinforced concrete containment buildings and shelters to resist blast loads is a complex process which involves a great deal of coordination between the engineer and contractor. The high density of reinforcing normally present in these types of structures necessitates close scrutiny by the designer to anticipate fabrication and construction problems. Solutions to these problems are much less expensive to incorporate in the design office than in the field. The problem many designers face is a lack of firsthand information regarding construction techniques for these types of buildings. It is almost impossible to fully appreciate the extent of these problems without observing the actual construction. This paper attempts to point out some of the most common problem areas to assist the engineers in evaluating their designs. Discussion is provided regarding rebar congestion, lacing placement, honeycombing, concrete placement, blast door anchorage, and other problems which frequently occur in construction of blast resistant, reinforced concrete containment bays and shelters. Causes of the problems and suggested solutions are addressed. These discussions will facilitate evaluation of designs by designers, independent reviewers, and sponsoring agencies. This paper reflects the experience of many design professionals involved in blast resistant design and construction obtained through informal surveys.
