Designing Buildings With Overhead Cranes

INSTRUCTOR: Alexander Newman, P.E., F.ASCE

Course Length: 1.5 Hours

Sponsored by ASCE's Structural Engineering Institute and ASCE Continuing Education. 

"The instructor did a great job presenting the broad points as a checklist with enough detail for use."

Purpose and Background

Industrial buildings with overhead cranes present a particular set of challenges for structural designers. The crane manufacturers design the proprietary framing and nonstructural components of the cranes themselves. The design of crane supports, however, belongs to the building structural engineers. These engineers often have many questions about structural requirements for the buildings intended to house overhead cranes.

What type of overhead crane is best suited for the application at hand? Which support scheme is optimal for the desired crane capacity? Is the structural frame rigid enough for a trouble-free operation of the crane? What if there are a number of cranes within the building? Which deflection criteria should be used for runway girders? Can an over-head crane be added into an existing metal building system? And just how much headroom and lateral clearance is needed for the proposed crane type and capacity?

The webinar discusses these and many other practical issues involved in the design of buildings with overhead cranes. It covers the most common types of overhead cranes used in industrial buildings, such as monorails, under-hung cranes, and top-running cranes. For each crane type the instructor discusses the range of the available capacities and the support alternatives for structural-steel and pre-engineered buildings. You will learn about the design criteria for crane runway beams and discover the publicly available software and sources for the design of crane girders, monorail-supporting beams, and stepped columns.
