Abstract
During 14th to 16th of February in 2014, a number of steel buildings were damaged by heavy snow in the capital region of Japan. As for long-span steel roofs (e.g. gymnastic hall), some cases of complete collapse were reported. In this paper, first of all, snow load is analyzed based on the fact of this disaster. And then, focusing of some structural types of steel roof, the elasto-plastic behaviour is examined through numerical analyses in order to obtain fundamental information for snowproof design of steel structures. Static elasto-plastic analyses of some type of steel roofs are carried out. The characteristics as a snowproof structure are examined. In this paper, 3 types of 30m-span girder that support roof are focused, (1) single wide flange, (2) truss structure, (3) beam string structure.
