This paper investigates the behaviour of hybrid fibre, i.e. a combination E glass and basalt added in reinforced concrete column. A total 6 columns were cast with Conventional Concrete (CC) Hybrid Fibre Reinforced (HFRC) to study structural performance The was made cement, manufacturing sand (m-sand), coarse aggregate as major ingredients. In column, 2% Basalt fibre along E-Glass 1% make HFRC. ...

The present study addresses optimal design of reinforced concrete (RC) columns based on equivalent equations considering deformability regulations of ACI318-14 under axial force and uniaxial bending moment. This study contrary to common approaches working with trial and error approach in design, at first presents an exact solution for intensity of longitudinal reinforcement in column section by...

This paper presents a study that forms part of an ongoing project on the seismic retrofit of reinforced concrete (RC) structures with fibre-reinforced polymer (FRP). In this study, a stress-strain model for FRP-confined concrete subjected to cyclic loading was implemented into OpenSees to support the performance-based design of FRP jackets for the seismic retrofit of RC columns/structures. Init...

fiber reinforced polymers (frp) have widely used for the purposes of enhances strength and ductility of concrete columns. proper design of such hybrid columns, however, requires a better recognition of the behavior of concrete columns confined with frp. in this paper, the influence of frp thickness, concrete compressive strength, and column size on the performance of eccentrically loaded reacti...

Nowadays, concrete with strength higher than 50 MPa is utilized due to the ever increasing need for higher strength and prolonged healing properties. Despite the widespread use of high-strength concrete, only a few research projects have been conducted on the punching shear strength of high-strength concrete slabs. Reinforced concrete flat slabs are widely employed in structural systems. The lo...
