Blast Design Considerations for Pre-Engineered Metal Buildings

June 24, 2020 | Starts at 11:00 am CDT

Practical Blast Design Considerations for Pre-Engineered Metal Buildings

Critical infrastructure and assets must be designed for blast resistance to promote safety and structural integrity. This webinar will review common design flaws within pre-engineered metal buildings (PEMBs) as seen at petrochemical facilities and refineries, providing insight into effective metal building design for blast loads.

During this webinar, we'll demonstrate the complexities with respect to blast design and the need to use a qualified extreme loads and structural risk advisor to support your design efforts. We'll also solicit questions regarding the appropriate design of metal buildings for blast. Join this webinar to understand more about design considerations when structural building projects arise. 

What We Cover

  • Common issues within metal building design
  • Blast resistant considerations
  • Overview of execution at the plant level for constructing new PEMB or retrofitting existing PEMB

Chris Leboeuf

Chris Leboeuf, P.E., CP Blast is a Technical Manager in the Extreme Loads and Structural Risk Division at ABS Group. Leboeuf is a licensed professional engineer in multiple states with over 18 years professional experience as a structural engineering consultant. He specializes in dynamic analysis and design of structures and equipment to mitigate hazards from extreme loading events, including vapor cloud explosions, jet fires and bursting pressure vessels. LeBoeuf works extensively with industry explosion safety criteria documents such as NFPA 68; ASCE Design of Blast Resistant Buildings in Petro-Chemical Facilities; CCPS and AIChE Guidelines for Evaluating the Characteristics of Vapor Cloud Explosions, Flash Fires, and BLEVEs; and similar criteria documents. He has performed more than 50 site surveys to collect data on over 500 buildings. He has worked closely with facility owners, architects and contractors to implement upgrades from conceptual design through building commissioning. In addition, LeBoeuf has performed dynamic finite element analyses for a variety of related issues for petrochemical clients. He has used state-of-the-art finite element codes to analyze structures, structural components, facilities and equipment (e.g. storage tanks, blast chamber, pipe failure) for nonlinear response when subjected to adverse loading conditions and for assessment of conditional performance. LeBoeuf is a principal instructor for multiple short courses dedicated to understanding explosion effects and dynamic structural analysis, including Facility Siting and Consequence Modeling - API 752/753. LeBoeuf also participates as a member on the API 752/753 committee.

Johnny Waclawczyk

Johnny Waclawczyk, P.E., is Director, ELSR at ABS Group's San Antonio Office. He has over 25 years of experience designing and analyzing structures subjected to blast loads produced from high explosives (HE), vapor cloud explosions, bursting pressure vessels and venting dust explosions. He has designed and tested a variety of structures including blast resistant buildings, containment structures and blast chambers. Waclawczyk has used state-of-the-art finite element codes to analyze the nonlinear response of structures under blast loads. He has developed 2-D and 3-D models for analysis of building components, structural frames and blast containment vessels utilizing shell elements, solids and full contact impact surfaces. He has worked with a variety of client owners, architects and contractors to develop new designs and upgrades from conceptual design, through construction, and building commissioning. Waclawczyk is familiar with recognized blast design documents such as UFC 3-340-02 (TM5 1300), Structures to Resist the Effects of Accidental Explosions, DOE/TIC-1128, A Manual for the Prediction of Blast and Fragment Loads on Structures, ISC Security Criteria, GSA Security Reference Manual (Blast Design and Assessment Guidelines) and ASCE's Design of Blast Resistant Buildings in Petrochemical Facilities. He is a member of the ASCE 59 committee for Blast Protection of Buildings and a principal instructor for courses dedicated to understanding explosion effects and dynamic structural analysis including Facility Siting and Consequence Modeling - API 752/753. Waclawczyk is a licensed Professional Engineer.
