Wang and Belarbi  reported that the addition of polypropylene fibers to concrete resulted in small crack widths and adequate ductility indices in beams reinforced with carbon FRP (CFRP) and Experimental and analytical investigation of high This paper investigates the flexural performance of engineered cementitious composite (ECC) concrete beams reinforced with innovative hybrid bars. Hyb FRP materials for the rehabilitation of tubular steel Oct 01, 2007 · The beams were part of a structural frame of a historic building dating back to 1903 and needed to be strengthened because of loss of flexural capacity due to corrosion damage and to accommodate an anticipated increase in floor loading. In both applications, composites showed very good potential for use in the rehabilitation of metal structures
Ductility is the one of the major property in the construction of structural elements. Especially in beams, the ductility plays a vital role to sustain the loads. In reinforced cement concrete, steel will possess a good ductile behaviour comparatively than the concrete. Concrete is generally brittle material and Full Proceedings - Free Online Publishing56 (b) Test 1 beam (a) Test 2 beam Fig. 7 Beam mid-span deflection with respect to beam bottom flange temperature of Tests 1 and 2 4 CONCLUSION A 3D finite-element model of unprotected axially-restrained tubular steel beams was developed using ABAQUS software (2008).

Nayera Ahmed Abdel-Raheem Mohamed A - DocShareas beams, one-way and two-way slabs, and, recently, columns (Kassem et al. 2011, Bakis et al. 2002, El-Salakawy et al. 2005, Sharbatdar and Saatcioglu 2009, Tobbi et al. 2012). Constructing a multistory building with adequate stiffness using FRP reinforcement calls for investigation into the behavior of shear walls totally reinforced with FRP.
In general, the FEA predicted with very good results the de-bonding of the GFRP-to-concrete interface of T-beams externally bonded with GFRP composites. Non-linear analytical model of composites based on basalt textile reinforced mortar under uniaxial tension , Larrinaga, Pello, Chastre Carlos, San-José José T., and Garmendia Leire Seismic Strengthening Strategies for Heritage Structures Moreover, although European and national codes (e.g., Italian Ministry of Cultural Heritage and Activities 2006) suggest the use of various systems for the strengthening of connections, for example, ring beams, no detailed reference is made to specific procedures for the dimensioning and checks of such elements.The only indication in this sense can be found in Section 6.1 Retrofit Design Sprayed glass fiber reinforced polymers in shear Shear failure of reinforced concrete (RC) beams is often sudden and catastrophic. A timely shear strengthening of deficient RC beams is therefore critical in view of maintaining public safety. In this dissertation, the effectiveness of externally bonded sprayed glass fiber reinforced polymer (Sprayed GFRP) in shear strengthening of RC beams under both quasi-static and impact loading was

Structural systems notes - LinkedIn SlideShareJun 11, 2018 · Accordingly, special concentrically or eccentrically braced frames were later developed with extensive design requirements, and are frequently used in areas of high seismic risk. The purpose of the concentrically- or eccentrically-braced design is to ensure adequate ductility (i.e., to stretch without breaking suddenly). We can work on Performance Analysis of New Hybrid Beams This work is published as a dissertation sample and a free dissertation example 1.1 Introduction Worldwide developments in civil engineering construction have created the need for new construction materials to support the structural progress, particularly in the case of severe construction requirements like large span girders or high-rise buildings.
Dec 01, 2013 · The failure loads of beams R, G2 and G3, predicted according to a plastic analysis, were in very good agreement with experimental data obtained for all beams. 6. In the parametric study performed using non-linear FE models of full-scale beams, for all cases analysed, linear elastic analysis provided conservative predictions of the design load
