Beam-to-Column Connections with Demountable Energy Dissipative Plates [PDF]
Frontiers in Built Environment, 2018 The behavior of steel structures subjected to seismic actions depends directly on the connections behavior. There are two current tendencies for ensuring the structural ductility: allowing the formation of plastic hinges in the beams by using reduced ...

Demountable connections of reinforced concrete structures: Review and future developments
Structures, 2021 Abstract In the current practice, at the end of life of a reinforced concrete structure, it is destructively demolished and the demolition waste is landfilled or recycled. This approach is clearly wasteful of energy, creating serious environmental pollution and at high cost.

Behaviour and Design of Connections for Demountable Steel and Composite Structures
Structures, 2017 Abstract This paper provides an overview of demountable connections and elements for steel and composite structures. Demountable connections are generally assembled from prefabricated structural members which can be reused after dismantling. This paper investigates innovative connections which enable steel and concrete framed structures to be made ...

Performance Evaluations of Demountable Electrical Connections [PDF]
, 1994 Electrical conductors operating in cryogenic environments can require demountable connections along their lengths. Such connections must have low resistance and high reliability and should allow ready assembly and disassembly. The pelformance of two types of connections has been evaluated. The first connection type is a clamped surface-to-surface joint.

Shear tests on demountable precast column connections [PDF]
Structural Concrete, 2021 AbstractLately, there has been increasing demand for structural solutions and building technologies with minimalized CO2 footprint. One way to approach the carbon neutrality is through reuse of structural components. In order to enable economic reuse of precast concrete elements, their connections must be designed to allow an effortless dismount. While

Local behaviour of the connector with mechanical coupler and rebar anchor under tension load [PDF]
Građevinski Materijali i Konstrukcije, 2023 In the past few decades, demountable connectors have often been used for connections in composite and mixed steel-concrete structures to reduce construction time and costs.

Experiment and numerical modelling of a demountable steel connection system for reuse [PDF]
Journal of Constructional Steel Research, 2022 Currently, steel reuse is only a marginal practice. To facilitate deconstruction and efficient reuse of steel components, an innovative connection system was proposed. This system adopts a ‘Block Shear Connector (BSC)’ that allows beam length to be standardised and suitable for a wide range of different sizes of the supporting members within the same ...

Numerical Study on the Bending Resistance of Lightweight Built-Up Steel-Concrete Composite Beams
Applied Sciences, 2023 This paper investigates the bending resistance of an innovative lightweight composite floor system, LWT-FLOOR. The system consists of built-up cold-formed steel elements that are spot-welded and connected to the concrete slab using demountable shear ...
