This study presents a study on the ductility performance of hybrid fibre reinforced concrete. The influence of fibre content on the ductility performance of hybrid fibre reinforced concrete specimens having different fibre volume fractions was investigated. The parameters of investigation included modulus of rupture, ultimate load, service load, ultimate and service load deflection, crack width...

Are structural engineers designing concrete structures with greater capacity and safety than they realize? By exploring effects of confinement in order to incorporate them in usual design procedures of engineering consulting companies, concrete structures will possibly in the future be both stronger, thinner and have a greater ability to deform prior to failure – three properties that are highl...

in this paper, moment-curvature behavior and ductility of prestressed concrete members based on nonlinear analysis is investigated. influence of various design parameters on ductility of flexural members is determined according to appropriate materials models for stress-strain curves of concrete, prestressing steel and conventional reinforcements. parameters studied include reinforcing index (ω...

The present study examines the new generation of concrete. Concrete has long been a major problem, is its ductility. Traditionally, remembering the words of concrete, compressive strength also comes to mind. Compressive strength is not only parameter of necessary and sufficient for a material. Concrete is basically brittle material. By adding the steel in this material is an attempt to ductile ...

Flanged shear walls are used extensively in moderate- and high-rise buildings to resist lateral loads induced by earthquakes. The seismic performance of many buildings is, therefore, closely linked to the behavior of the reinforced concrete walls. They must be carefully designed to provide not only adequate strength, but also sufficient ductility to avoid brittle failure under strong lateral lo...

This paper evaluates the behavior of channel shear connectors, embedded in a concrete slab, with different concrete materials. The results of a series of limited push-out specimens were presented and discussed. The push-out tests comprise of channel shear connectors in different types of concrete. Reinforcement was included in some specimens, as well. The results showed that using reinforcement...

Recently, steel fibre reinforced polymers (SFRP) sheets have been introduced for the repair and rehabilitation of concrete structures. Few researchers studied the behaviour of the concrete columns wrapped with SFRP sheets; however, several critical parameters such as the cost and ductility effectiveness of the SFRP wrapped concrete columns have been lightly addressed. Thus, the main objective o...

This paper is concerned with the inelastic behavior of axially loaded concrete-filled thin-walled steel tubular columns subjected to local buckling. A nonlinear fiber element analysis program accounting for local buckling effects is developed for predicting the ultimate strength and ductility of concrete-filled thin-walled steel tubular columns. The effects of local buckling are taken into cons...
