Profile steel-ultra-high performance concrete composite beam

SHEN XIUJIANG / SHAO XUDONG

The invention discloses a profile steel ultra-high-performance concrete composite beam, which comprises inverted T-shaped steel and an ultra-high-performance concrete T-shaped beam, and the ultra-high-performance concrete T-shaped beam comprises an ultra-high-performance concrete wing plate arranged transversely and an ultra-high-performance concrete web arranged longitudinally. Reinforcing ribs are arranged in the ultra-high performance concrete wing plate and the ultra-high performance concrete web, the inverted-T-shaped steel comprises steel wing plates arranged transversely and steel websarranged longitudinally, shear keys are continuously arranged on the steel webs, and the shear keys are wrapped in the lower ends of the ultra-high performance concrete webs. The profile steel ultra-high-performance concrete is simple and reasonable in structure, easy and convenient to construct, free of material loss, light in self weight and excellent in stress performance, and can effectively solve many problems existing in an existing steel-concrete composite beam structure.
