Abstract

AbstractLarge-span spatial steel structures are subject to complex stress conditions during construction, especially during the unloading phase, and they are easily affected by the environment and ...

Highlights

Since the twentieth century, large-span spatial structures have been widely used in public buildings, such as stations, exhibition centers, and stadiums, because of their light weight, large internal space, high flexibility, low damping, low natural frequency, and good seismic performance (Chen et al 2011)
The results show that the prefabricated construction method and the steel columns-scaffold combination support system are suitable for the large-span and high-load floor structure
This paper investigates the effects of different construction methods on the mechanical state of a truss structure

Summary

Introduction

Large-span spatial structures have been widely used in public buildings, such as stations, exhibition centers, and stadiums, because of their light weight, large internal space, high flexibility, low damping, low natural frequency, and good seismic performance (Chen et al 2011). After all the principal and secondary trusses are welded to the supports through connecting rods, the steel strands in each lifting position are cut to complete the process of fixing the trusses.
