Application of Precast UHPC Web Members for Long-span Bridge Structures

Original language description

UHPC is a modern material with great characteristics and shows all important properties for efficient structural design and construction process. Its applications lead to optimization of structures and to minimization of material consumption. The paper focuses on the application of slender precast UHPC slabs, which lighten monolithic bridges constructed by free cantilever method. The principle comes from constructed bridge: Takubogawa Bridge, Japan. The aim of this paper is to present basic theoretical background behind the structural applications of UHPC webs. Additionally, 3D bridge model of composite system with box cross section was created with application of UHPC precast webs and monolithic upper and lower slab. The behavior of the structure was analyzed and compared to conventional monolithic bridge model constructed by free cantilever method. The focus lies with detailed analysis of behavior of the UHPC webs. The paper also describes alternative approaches of lightening webs of box cross-section using steel members such as webs from corrugated steel sheet or steel truss.
