Crane-Supporting Steel Structures: Design Guide

Update: 2025-12-14

Description

Provides extensive engineering criteria for the design and analysis of steel structures meant to support overhead cranes and similar machinery. The central focus is on fatigue considerations due to repeated loading, which is presented as the most crucial factor often superseding traditional ultimate limit states in structural calculations. The text details methods for assessing and mitigating damage from cyclic loading, including calculating dynamic loads, stress ranges, and equivalent cycles based on duty cycle analysis and specific detail categories. It offers comprehensive procedures for the analysis of crane-supporting elements, covering complex sections like mono-symmetric beams and heavy plate girders, often employing theoretical methods such as the flexure analogy. Finally, the source offers practical measures and checklists for construction detailing, proper alignment, maintenance, and the rehabilitation of existing crane runways to ensure long-term structural integrity.
