Hybrid FRP-Concrete-Steel Multitube Concrete Columns: Concept and Behavior

Journal of Composites for Construction, 2017
AbstractThis paper presents the conceptual development of a new form of hybrid structural column, termed the hybrid fiber-reinforced polymer (FRP)-concrete-steel multiple-tube concrete column (MTCC...

Performance of HYBRID fibres in concrete

Materials Today: Proceedings, 2021
Abstract In modern world, the usage of Fibre Reinforcement Concrete has become vast in Civil structures. FRC can immunize the Tensile strength of structures with dispersed and scattered fibres. While doing some practical research on concrete which invigorate the fibre development in order to shrinkage, which resulted in fibre reinforced concrete. The

Development and Hybridity Made Concrete in the Colonies [PDF]

Environment and Planning A: Economy and Space, 2008
The concept of hybridity has been discussed chiefly in relation to cultural issues and interpreted as a challenge to dominant power. It is equally relevant to the interpretation of economic and social change (for example, in the field of international development), while its political significance is properly a subject of investigation.

HYBRID FIBER REINFORCED CONCRETE

2007
This paper describes the mechanical performance of hybrid fiber concrete with a maximum fiber dosage of 0.75 Vol.%. Two types of fibers were used: short straight steel fibers and long hooked-end steel fibers. The concrete compressive strength (fc,cub150) varied between 55 and 65 MPa, dependent on the fiber mixture.

Behaviour of concrete beams with hybrid reinforcement

Construction and Building Materials, 1994
Hybrid reinforcement for concrete members consists of rods made with an FRP (Fibre-Reinforced-Plastic) skin over a steel core. The FRP skin is made of braided, epoxy-impregnated aramid or vinylon fibre. This paper presents experimental and analytical results for beams reinforced with hybrid rods for the evaluation of the flexural behaviour of the ...

Hybrid NDE for Rebar Corrosion in Concrete

2016
Corrosion of reinforcing steel-bar (rebar) is modelled phenomenologically as corrosion losses of three phases. Corresponding to these phases, high AE activities are characteristically observed twice during the corrosion process. It is shown that the 1st AE activity corresponds to the onset of the corrosion in rebar and at the 2nd period of high ...

HISTORY OF CONCRETE APPLICATION IN DEVELOPMENT OF CONCRETE AND HYBRID ARCH BRIDGES

2008
Young engineers live in a permanent state of now and today without any connection to the past, which is missing even in their lifetime. This makes the historians and their task to remember what others have forgotten even more important. In this overview development of concrete as a material and contribution of the concrete application history in ...
