System Requirements for Viewing this Course

Sponsored by ASCE Continuing Education and the Structural Engineering Institute (SEI).

INSTRUCTOR: Dave K. Adams, P.E., S.E., M.ASCE

Course Length:  90 minutes

Purpose and Background

ASCE 7 contains minimal assistance in designing horizontal, saddle-supported tanks, though these can be quite common on the site of an industrial facility. This webinar helps the attendee discover means for calculating seismic forces and resulting stresses on these types of vessels, with additional emphasis on specifying an appropriate shell thickness.

Primary Discussion Topics

• Seismic loading using ASCE 7-16
• Tank shell stresses due to combined loading (with seismic)
• Geometrical parameters for tank and saddle supports
• Performance of saddle supports

Learning Outcomes

• Define seismic loading using ASCE 7-16 and other publications
• Calculate tank wall stresses and specify required steel thicknesses
• Evaluate the requirements for saddle supports
• Determine steel reinforcement required for concrete saddle supports

Webinar Benefits

• See how a variety of publications clarify the design process
• Understand the limitations of ASCE 7-16 in the analysis and design process
• Discover economical geometric arrangements of structural supports
• Understand the process for determining required steel tank thicknesses
• Explore requirements and design of concrete saddle supports

Intended Audience

• Engineers
• Industrial facility engineers or project managers
• Building officials
• Steel tank manufacturers/fabricators

Webinar Outline

• Introduction
