Traditionally, reinforced concrete (RC) walls have long been adopted as an efficient lateral load resisting systems to enhance the stability and integrity of the buildings against dynamic actions such as wind, earthquakes etc. Later, steel plate walls were proposed as a promising alternative of concrete walls. Thin steel plate walls contributed in weight reduction of the structure with greater ...

Timber–concrete composite systems are widely used in Europe, North America, and Australasia, primarily due to their good mechanical performance terms of statics, dynamics, seismic response. In addition, the concrete slab provides excellent protection timber, making such suitable for outdoor application. The timber–concrete composites is normally governed by ductility energy dissipation capacity...

This report deals with the experimental investigation of using large deformable FRP, ± 45° oriented fibers, in concrete-filled fiber tubes (CFFT) under axial cyclic compressive loading. In addition, this report presents finite element modeling (FE) of CFFTs with large rupture strain FRP (LRS-FRP). The LRS-FRP is made with polyethylene naphthalate (PEN) and polyethylene terephthalate (PET) fiber...

The (brittle) behavior of concrete, although used in many fields, impedes its use some applications that require (flexible) behavior, wherefore several types fibers were utilized among them polypropylene fiber (PPF), enhances pre-crack tensile strength, toughness, ductility performance, impact resistance, flexural strength and failure mode. This paper submits a comprehensive review previous stu...

Currently, ordinary concrete and steel bars are mostly used in frames, but there is no systematic research on the impact of high toughness low yield point seismic performance frames. The low-cycle repeated load test three 1/3 ratio two-story two-span cast-in-situ frame specimens carried out. resilience model hysteresis characteristics, displacement ductility, energy dissipation capacity studied...

Abstract:   The use of Concrete beams reinforced with a combination of fiber reinforced polymer (FRP) and steel bars has increased dramatically in recent years, due to improvement in strength and flexural ductility simultaneously. In this paper, we proposed a new equation for estimating the effective moment of inertia of hybrid FRP-steel reinforced concrete (RC) beams on the basis of the...
