Reinforced concrete (RC) frames subjected to seismic loading often depict localized member-end deformations due to strain penetration effects between adjacent members, such as beam-column and column-footing joints. Past experimental programs indicate that the bond-slip deformations occurring at the interface between the reinforcement and the surrounding concrete can contribute up to 40% of the ...

Flat slab concrete buildings are widely found in infrastructure such as office and residential buildings or industrial facilities. The susceptibility of progressive collapse of such structures due to accidental loads is highly dependent on the structural performance of the slab-column connections. This paper presents a framework for a simplified reliability analysis and derivation of safety fac...

The majority of columns are subjected to a combination of an axial load and a bending moment in one or two directions. With a few exceptions, most of the research in the area of FRP wrapped columns have concentrated on the behaviour of concentrically loaded columns. This paper presents results of testing nine reinforced high strength concrete columns. The column specimens are circular in shape ...

Accurate assessment of demand and capacity of structures is critical in developing performance-based design methodologies. In this research, new methods are presented towards quantifying demand and capacity of RCFT frames and members. An experimental database was compiled documenting local damage levels of RCFT members. The quantified information collected from the experiments was utilized in c...

The main objective of the study is to determine behavior built-up cold-formed steel (CFS) stub columns infilled with washed bottom ash (WBA) concrete and also their failure mode. Five proportions WBA as sand replacement in five specimens CFS are produced this study. There four parts testing conducted: material properties CFS, concrete, mechanical connection, columns. result shows that specimen ...

a r t i c l e i n f o Keywords: Concrete-filled steel tube (CFST) Confinement effect Fuzzy logic Modified learning from example (MLFE) Axial load capacity A circular concrete-filled steel tube (CFST) has several advantages compared with the conventional reinforced concrete member or hollow steel tube, since the tri-axial state of compression of the concrete infill increases its strength and str...

The steel-concrete composite column comprises a steel core and surrounding concrete. purpose of the system is to provide analysis design techniques for newly invented class laced short columns cyclic axial loads. To minimize increasing density issues associated with nominal strength concrete in consideration depletion natural resources required produce concrete, factory-obtained lightweight sin...

The principal objective for this work was to extend the field of application FEM space frame beam-column connections under static loading and with lateral displacements. A four-storey building modelled load condition. Horizontal vertical structural elements were designed according Eurocode 2. In order understand behavior external node made by column, two beam upper models using correct boundary...

This paper explores the effects o f adding synthetic reinforcing fibres to highstrength reinforced concrete columns and in particular only to the cover o f the columns. An experimental program was conducted where seven circular reinforced concrete columns were tested with varying fibre content one contained no fibres, two contained fibres throughout the cross-section and four contained fibres o...
