verifying the behavior of shear walls in a tall building requires reliable response results. this paper examined nonlinear fiber element modeling of a slender reinforced concrete shear wall during large-scale shaking table testing. the goal was to understand and validate the inelastic responses given by fiber models using time history analysis. reasonable agreement was found between the numeric...

Concrete is the most used construction material in world; however, its deficiency shrinkage and low tensile resistance undeniable. Used as secondary reinforcement, fibers can modify concrete properties various ways. Carbon-fiber-reinforced highly suitable to maintain longevity of infrastructure where corrosion steel shorten useful service life structure while polypropylene mostly improve concre...

In recent years many research on composite beams with innovative shear transmission with composite dowels have been conducted and innovative composite constructions have been built. One of the common types of shear connection is the method of rolled girders encased in a concrete slab. The combination of such method and pcb (precast composite beam) technology is called pcb-W (precast composite b...

Self Compacting concrete (SCC) is a flowing concrete that is able to consolidate under its own weight without any need for vibration. The high fluid nature of SCC makes it suitable for placing it in difficult conditions and in sections with congested reinforcement. Use of SCC overcomes the difficulties pertaining to casting conditions and reduces the man power required. Self compacting concrete...

frps (fiber reinforced polymer) possess many favorable characteristics suitable and applicable for construction industry when compared with steel reinforcement. there are new ideas to use frps as longitudinal or transverse reinforcement for new concrete elements particularly for bridge decks or beams. although high tensile strength of frp is main characteristic for applications at both areas, i...

This paper addresses the static properties and impact resistance of a ‘‘green’’ Ultra-High Performance Hybrid Fibre Reinforced Concrete (UHPHFRC). The design of concrete mixtures aims to achieve a densely compacted cementitious matrix, employing the modified Andreasen & Andersen particle packing model. The flowability, static mechanical properties and impact resistance capacity of UHPHFRC are m...

This paper presents the findings of an experimental program aimed at investigating the strain distribution between Carbon Fiber Reinforced Polymer (CFRP) sheets and concrete. CFRP is used as externally bonded reinforcement for concrete structures to improve flexure and shear strength and confinement of concrete. The effects of bonded length, concrete strength, and number of plies (or stiffness)...

In engineering design, the strength analysis of concrete structures heavily depends on compressive hybrid fiber reinforced (HFRC), which also has an impact stability and safety structure. The objective this study is to develop a unified empirical model that can quickly estimate under multiaxial compression. To measure concrete, 108 cylindrical specimens 225 cubic were designed for conventional ...
