This is an ASCE Micro Learning Seminar consisting of short modules and videos for ease in consuming and learning.
INSTRUCTOR: Dave K. Adams, P.E., S.E., M.ASCE
Course Length: 5 hours
Purpose and Background
Chapter 15 of ASCE 7-10 contains miscellaneous provisions for calculating seismic forces to be applied to a variety of tanks and vessels. A number of agencies also publish design standards for tanks of different materials and configurations, many of which are at some variance with the latest edition of ASCE 7. Additionally, the wind load provisions for tanks can be different among these many standards depending on material and governing load combinations. Through the presentation commentary and worked-out numerical examples, this course intends to guide the participant through design principles outlined in various tank design standards using ASCE 7-10 as the source document for defining loads for analysis.
Learning Outcomes and Benefits
Vertical Flat-Bottom Tanks Storing Liquids
- Discover necessary seismic equations from Chapter 15
- Determine tank wall stresses due to fluid and lateral forces
Elevated Vessels Storing Solids
- Understand how the properties of bulk solids affect vessel performance
- Calculate silo leg anchorage to concrete
Horizontal Saddle-Supported Vessels Storing Liquids
- Consider simplified methods to account for sloshing effects
- Review shell combined longitudinal stress due to weight and seismic load
Tanks or Vessels Supported on Structural Towers
- Determine appropriate wind and seismic forces for the vessel and the tower
