Ferrocement-Timber Composite Beams Loading capacity

Abstract

This paper presents an experimental study of simply supported ferrocement timber composite members. An adherently bound link is investigated. As a shear connector layer, an appropriate length for this type of composite beam was chosen to study the effect of shear strength on the impact of one point load (1.2 m). Sikadur 31 thixotropic epoxy resin adhesive is used. The research's primary goal is to collect data and provide information on the structural behavior of proposed ferrocement timber composite (FTC) beams. The thickness and width of timber beams, the presence and absence of a bonding layer on the shear connector, and the influence of sagging and hogging bending moments were also investigated. FTC beams are a relatively new civil engineering solution, and their behavior should be investigated to develop relevant methods for calculating their resistance. Two push-out tests were used to tentatively resolve the connector's slip and pinnacle load limits. The stiffness and strength of the connection utilized to bind a ferrocement slab to a timber beam were investigated by the authors. These criteria are critical for composite beam planning because the solidity and quality of a composite beam framework's connections determine its performance. A three-point loading test was performed on the composite beam specimens. Measurements also demonstrate that the connection is near-perfect because the slide is minimal during the test (except at failure). Converting from sagging to It has been witnessed that converting from sagging to hogging bending reduces the ultimate load by up to 24%. The suggested beams' loading It has been witnessed that Converting from sagging to hogging bending reduces the ultimate load by up to 24%.shown to be excellent when compared to their weight in tests. Epoxy resin (Sikadur 31) can be used to provide adequate bonding between the components. The highest gain in the loading capacity was 48% when the timber thickness was increased from 90 to 190 mm.
