Blast Hardened Retrofit Details for Petrochemical Buildings
This paper presents actual cases for evaluating existing buildings within petrochemical facilities subjected to postulated vapor cloud explosion blast scenarios. An evaluation will estimate the expected damage (i.e., Light, Moderate, Severe, Failure) to each building component that makes up the exterior building envelope. If an unacceptable cumulative overall building damage is assigned and a decision is made not to de-occupy the building then upgrades to the building to significantly enhance its current blast capacity are required. Based on operational, construction, and existing cable and control panel configurations, a cost effective retrofit option is selected. The paper will describe several upgrade techniques such as building a new building around the existing building and adding reinforcement bars or steel posts to exterior concrete masonry walls and framing a new steel frame roof over the existing roof. The discussed retrofits are based on analytical dynamic non-linear models that were used in their design. Some of these analytical models have been validated with test data produced using the BakerRisk shock tube.
