Characteristic analysis of acoustic emission monitoring parameters for crack propagation in UHPC-NC composite beam under bending test

, 2021
Ultra high performance concrete (UHPC) has more outstanding mechanical properties and durability than normal concrete (NC) materials. Currently, analysis methods for the mechanical properties of UHPC structures and UHPC composite structures, such as ...

Numerical analysis on shear resistance of ultra‐high performance concrete‐normal strength concrete composite beam

Structural Concrete, 2021
Ultra‐high performance concrete‐normal strength concrete (UHPC‐NC) composite beam is a brand‐new composite structure. UHPC‐NC composite beam not only has the interfacial problem of the two materials, but its shear resistance should be investigated, which

Dynamic performance of composite beam-column connections subjected to impact loadings

, 2021
In this paper, two typed steel beam-column connections (Welded Unreinforced Flange-Bolted Web (WUFB) connection, Bolted Unstiffened End Plate (BUEP) connection) with and without reinforced concrete slab were experimentally examined under impact loadings.

Advances in composite beams with web openings and composite cellular beams

Journal of Constructional Steel Research, 2020
Abstract In the last two decades, civil construction has used steel elements to compose the structural framework. The use of composite elements of steel and concrete in multi-storey buildings has been gaining market share in several countries, mainly due to the possibility of reducing the height of the building, the structure's own weight and the ...
