Composite capping beam with steel beam and ultra-high-performance concrete plate and construction method therefor

Abstract

Disclosed is a composite capping beam with a steel beam and an ultra-high-performance concrete plate. The composite capping beam includes a steel beam and an ultra-high-performance concrete (UHPC) plate, where the steel beam includes a bottom plate and web plates, the web plates are arranged at two sides of the bottom plate in a longitudinal bridge direction, bottoms of the web plates extend downwards to be provided with lower extension sections, and the UHPC plate is clamped in a cavity defined by the lower extension sections and the bottom plate. The present disclosure further provides a construction method for the composite capping beam with a steel beam and an ultra-high-performance concrete plate. The composite capping beam with a steel beam and an ultra-high-performance concrete plate according to the present disclosure is small in hoisting weight and economical.
