Abstract
A long span steel roof truss is the preferred structural system for column free enclosures used in industrial, commercial and institutional applications because the forces of the structure can be determined as predominantly axial member forces due to the triangulation. The structural efficiency of this type of roof, however, relies in part on the internal geometry of the truss, and also on the cross sectional shape of the members, and their interaction under lateral (wind) loading has been little discussed in the literature systematically.This review brings together and combines previous research (2004-2019) on gravity and wind-load behaviour of steel roof trusses, and recent developments in wind-load code provisions, computational optimisation (2020-2025) and structural health monitoring, and compares this to a nine-configuration STAAD.Pro case study for Fink, Howe and King Post trusses for angle, channel and ISMB sections.Lateral loading tests have shown that the Howe truss is the one having a more uniform distribution of forces under lateral loading than the Fink and King Post trusses and rolled steel beam (ISMB) sections are the stronger and more serviceable sections than channel and angle sections. The quantity comparison of the different cost also indicates that Howe truss configuration using ISMB sections is the least cost. Recently, computational studies demonstrate that the code-compliant section selection is not the only way to save material; with metaheuristic and machine learning based optimisation methods 15-25% of material can be saved.Other potential avenues of research include other long-span truss configurations and combinations of wind and seismic loads, comparing optimisation algorithms with traditional designs, performing a life cycle cost and embodied carbon analysis, and field instrumentation of existing long-span trusses.
