Static Analysis of Load-Bearing Structure of a Transparent Roof

Abstract:

This paper deals with static analysis of load-bearing steel grid of a transparent roof. Ten structures with various spans (from 12.58 m to 30.08 m) and different heights (from 2.494 m to 7.471 m) have been modelled and analysed. The calculations were repeated for two common used types of the cross-sections - (60 x 40) mm and (60 x 60) mm. Permanent loads (the self-weight, the weight of glass panels) and variable loads (snow, wind) were taken into account. Obtained results were verified by four additional structures. The architects can use resultant graphs (the dimensions, maximum axial forces and maximum vertical displacements) in first stage of the design.
