Analytical Studies on the Behaviour of 3d Rc Frame with Ferrocement Panel as Infill

Masonry is a major infill material which is used in RC frames throughout the world; we have accepted that the masonry increases the stiffness of structure. The vertical live load and dead loads due to masonry do not pose much of problems to the RC frame in the absence of lateral forces of wind or earthquake, but concentrated masses of masonry accelerates the lateral forces during the affect of wind forces and earthquake forces. The frame exhibits diagonal crack failure at brick infill at a relatively slow rate of increase before they started to break down. After collapse of masonry infill, the infill frame shall act as a soft story so that the infill didn‘t take any load after collapse. In the present study Ferrocement panel is used as infill in place of masonry, because of its major advantages such as light weight, thin section, easy of construction, economy of materials total mass is less than masonry per length, better utilization of human resources and architectural flexibility in addition to these advantage it also create monolithic action. RC frame of four story, single bay, with Ferrocement panel as infill is generated using ETAB software. Assigned material properties, sectional properties, boundary conditions, dead load and lateral force in terms acceleration to the model, displacement controlled pushover analysis is carried out, the seismic performance of a buildings are evaluated in terms of i) Pushover curve, ii) Performance point and Capacity–Demand spectrum, iii) Plastic hinge formation etc
