Innovative Retrofit of Existing Buildings Subjected to Blast Loading: A Case Study
Most of the buildings built for industrial purposes are regular and rectangular with minimal protrusions and irregularities. The case study originates from a practical evaluation for a client where it was found that the existing plant buildings involved very light steel construction and had low redundancy in the structural systems. These buildings were at risk from accidental blast loads identified after their construction. The nature of the problem was that the building was operational, and the retrofit had to be done while the building is operational with minimum disruption to operations. The retrofit approach to use an open structure to strengthen the existing building reduces the amount of blast force that is exerted on the new structure as well as strengthening the existing structure for the reflected load. It also provides an alternative load path for the blast forces providing a high level of redundancy required for a blast-resistant structure. The paper presents an innovative crash-guard type open structure retrofit protecting the crumple zone on an operational control room building that is subjected to an accidental blast load. The retrofit improved the level of protection of the building significantly and minimizing the probability of structural collapse. The open structure retrofit improved the level of protection of the structure significantly reducing the risk to personnel in the building as well as saving millions of dollars for the client from the earlier proposed concept of a traditional closed sarcophagus around the building. The open structure concept caused minimum disruption to the existing building operations. It also provided significant savings on the construction schedule and plant production costs. The examination of the blast effect and the retrofit of two existing non-process buildings within a Petro-Chemical facility are presented in this case study.
