Abstract - This paper presents an experimental
particularly under lateral loads and also to investigate the effects of masonry infills on the strength and stiffness of steel frames and to explore various repair and retrofit techniques that can enhance their performance during seismic events. The conclusion driven are frames are significantly affected by the presence of infills, which enhance their lateral load capacity. Proper design and reinforcement strategies are essential to mitigate the risk of failure, particularly in the compressive corners of infill panels. And, it has been shown that the modulus of elasticity of the brick work material Ein obtained from the couplet tests grossly underestimates the overall stiffness of an infilled frame. An analytical approach for evaluation of a more accurate value for Ein has been put forward. The repair techniques, such as the application of concrete covers, are effective in restoring and enhancing the strength of damaged infill panels.
investigation on the behaviour of a 2D single bay two storey steel frames with Vertically and Horizontally folded ferrocement infill. Steel frame with flat and horizontally folded ferrocement infill is casted in the laboratory to a scale down of 1:3.3; the dimension of frame is 2.3 m height and 1m width. Channel Section ISLC 75 is used as beams and columns for the frame. The proposed model is subjected to lateral load at each storey level and their performance was assessed based on load carrying capacity and deflection. Experimental results are tabulated, compared with each other and conclusions are drawn. Key Words: Lateral Loading Frame, 2D Steel Bare Frame, Behaviour of Bare Frame.
1.INTRODUCTION
[2] N.Jayaramappa 2016, present study is aimed at determining the behaviour of ferrocement panel elements under lateral load. Sample size used were 1000 mm X 2000 mm X 30 mm size FERROCEMENT elements for lateral load test containing single, two, three and four layers of hexagonal chicken mesh and skeletal reinforcement were cast using cement mortar 1:3 (w/c= 0.5) and cured for 28 days. The elements fixed at base were progressively tested under inplane lateral load applied at top up to failure and their behaviors are compared. The results obtained were,
Ferrocement is not an unknown material now a days, ferrocement is multifaceted material made up of wire mesh, sand, water and cement which is different from reinforced cement concrete. Ferrocement has different quality of strength and unique serviceability. In this type of construction not required skilled labour. Ferrocement is not only used in building construction, even it can be used in water supply section like pipe, irrigation purposes, sanitation etc. various studies shows that ferrocement has good seismic resistant. Ferrocement is a very thin layer of mortar, covering reinforcement material such as steel bar, steel wire mesh. The thickness of ferrocement generally ranges to 25 mm to 50 mm. Ferrocement is an environment friendly sound technology and possesses excellent unique properties such as good tensile strength, improved toughness, water tightness, lightness, fire resistance, resistance to cracking and cost, time and material effective construction technology. The following definition was adopted by the ACI Committee "Ferrocement is a type of thin wall reinforced concrete commonly constructed of hydraulic cement mortar reinforced with closely spaced layers of continuous and relatively small size wire mesh. The mesh may be made of metallic or other suitable materials".
The load-deformation behaviour of Ferrocement panel acting as cantilever can be idealized to consist of three zones, Elastic zone, elastoplastic zone and plastic zone. The ultimate load, ultimate lateral displacement, modulus of elasticity and ductility of ferrocement panels subjected to Inplane lateral load increases with increase in volume fraction. As Vf increases by 1.52 times, the ultimate load and ultimate displacement increase by 1.23 and 1.64 times respectively. The modulus of elasticity of ferrocement panels acting as cantilever increase 1.32 times with increase in volume fraction of 1.52 times. The ductility of FERROCEMENT panels subjected to lateral loads increase 1.52 times with an increase in volume fraction of 1.52 times. [3] Somasekhar 2020, this researcher has explained the performance of plain and folded ferrocement panels under axial stress and to assess their load bearing capacity. Both the panels were cast and tested using the same dimensions and
