Abstract:Schemes of the large span floor in Heilongjiang Museum were compared. The three kinds of structures include steel grid structure, common prestressed concrete beam and prestressed concrete truss cable-beam. The structural performance, economic benefit and the effect on the architectural function of the three kinds of structures were compared in detail. The comparison results indicate that using prestressed concrete truss cable-beam in RC large span floors will get the best synthetical effect.

Keywords:large span floor; prestressed concrete truss cable-beam; steel grid structure; prestressed concrete beam
