The Occupational Safety and Health Administration (OSHA) published new requirements for the management of explosive
hazards in May of 1992. The OSHA Process Safety Management ofHighly Hazardous Chemicals regulations (CFR 29, 1910.119) requires
operating plants to perform a Process Hazards Analysis (PHA). The focus of theseregulations is on toxic, fire and explosion hazards.
In many cases a PHA reveals vulnerabilities due to the location and/or the struc-tural strength of occupied process plant buildings. This regulation, the recentheightened awareness of terrorist activities, and rising insurance costs has resultedin a drastic increase in the demand for structural consequence evaluations andengineering designs of buildings subject to explosion load. Advances in processand structural engineering now make it possible to design and analyze buildingssubject to external blast load from accidental explosions and terrorist bombs withacceptable accuracy.
This seminar teaches a proven and practical approach to this exciting engineeringdiscipline as developed by a practicing structural engineer with over 20 years ofexperience in the field.
– Apply ASCE's "Design of Blast Resistant Buildings in Petrochemical Facilities” to the dynamic design or analysisof a building subject to blast load.
– Establish the design criteria based upon “acceptableresponse level”
– Understand how the blast load is developed
– Obtain important information not necessarily provided withthe blast load data
– Generate useful design data from the blast load parameters
– Learn how to use “scaled” load history data for convenientanalysis of supporting elements
– Learn how to perform a structural dynamic analysis
– Obtain information about available analysis software
– Learn how to perform retrofit of existing buildings
– Develop a quick Qualitative Consequence Analysis of anexisting building based upon limited blast data
Each participant will receive a comprehensive seminar summaryand reference manual.
– Consulting engineers who would like to include BlastDesign in their portfolio.
– Structural design engineers who are responsible for thedesign of buildings that may be subject to blast load fromterrorist bombs or accidental explosions.
– Familiarity with blast design and ASCE’s “Design of BlastResistant Buildings in Petrochemical Facilities” is an advantage but not required.
JORGEN K. LIBER P.E., is a consulting engineer and owner of JKLConsult. He has over 41 years of varied experience in project
development, design, project management, and consulting. Histechnical expertise includes structural design and analysis, civil engi-

INTRODUCTION TO STRUCTURALDESIGN OF BLAST RESISTANT STRUCTURES– Evolution of blast resistant design
technology– Related industry guidelines,
specifications and codes– Blast resistant design process.
Flow chart
DEFINE BLAST LOAD– Terrorist bomb using explosive
materials– Equivalent TNT explosion method– Vapor cloud explosions– Standard– Air blast phenomena, deflagration,
detonation– Shock load. Pressure load. Far field
“shock-up” effect– Blast wind– Missiles, flying debris– Multi-Energy and Baker-Strehlow
method– Terrorist attack explosions
(detonations)– Blast load parameters and
characteristics. Location of epicenter– Overpressure, impulse, duration
( t / tn ), shock front velocity– Rarefaction effects.
Front/back phase shift– Negative phase and rebound– Design load. Blast load combined
with static gravity load (SGL) and environmental load
– Blast load on walls and roof (EQUAL software)
DESIGN CRITERIA– Universal acceptance. No government
codes– Response level– Ductility ratio– Hinge rotation
DAY TWO:
BUILDING DESIGN OR ANALYSIS– Building types and construction materials– Analysis method (equivalent static,
SDOF, MDOF)– Structural systems. Simplicity recom-
mended. Frames. Utilize ductility (ecc.x-brc.)
– System components. Beams, slabs,decks, braces, shear walls,diaphragms, columns, foundations
– Dynamic increase factor (DIF)– Strength increase factor (SIF)– Dynamic resistance of system compo-
nents. Load factors. Material factors– Now, forget all you know about Trans-
formation Factors!– Natural frequency– Scaling (method of using 1 load history
for multiple different elements)– Determine response level of structure
using SDOF method– Shear failure– Calculate uplift of foundations– Special details. Avoid load bearing
exterior walls. Uplift. Rebound– Doors, windows, openings. Internal
pressure due to openings– Design using TNT-equivalency method
(static design)
RETROFIT OF EXISTING BUILDINGS– Blast resistant glass, blast curtains, film– Connection details– OWSJ’s– Foundations
QUALITATIVE CONSEQUENCE ANALYSIS– A conventional building is reviewed

ASCE Distance Learning Program:
Wind Loads Online CourseThis course is an online version of the popular ASCE workshop. Topics includewind effects (e.g., Bernoulli's equation, patterns over buildings, and effects of roofgeometry), basic design wind speed, design wind loads, how to use the ASCE-7standard (plus three worked solutions), frequently asked questions, other codes,and where to get further information. After completing this course, you will beable to: explain basic air flow concepts and the effects of wind on structures;describe and calculate different wind speed measures; describe and calculate theparameters of the design wind speed equations, and; use the standard to calcu-late design wind loads. 8.0 PDHs.
