Abstract
Based on the structural advantages of trough beam and corrugated steel web, considering the capacity, durability and rapid construction of composite structure, a new type of composite structure beam is proposed in this paper, namely Composite Trough Beam with Corrugated Steel Web wrapped with Steel Plate (CTBCS). A scale experimental CTBCS was designed and fabricated to study the bending properties of failure mode, load-displacement curve and section strain distribution of CTBCS. In addition, the calculation method of bending capacity of CTBCS was proposed, and the effects of the thickness of steel plate, the diameter of steel bar in upper flange concrete slab and the height to span ratio on the bending properties of CTBCS were studied. The study in this paper provides reference values for the experimental scheme formulation of composite trough beam, and lays a foundation for the design and application of CTBCS.
