Behaviour of two storey RC frame subjected to lateral load

Abstract

Reinforced concrete (RC) bare frames are being used to resist lateral loads.These frames behaviour is depending on stiffness of frames and materials used.A two storey RC bare frame with single bay is tested for lateral loading at beam column joint in each storey.The dimension of the specimen such as beam, column and exterior, interior and top corner beam – column joints were designed as per IS: 13920-1993 recommendations. The test specimen was reduced to 1/4th scale to suit the loading arrangement and test facilities. Prototype specimen had beam dimensions of 230 mm x 350 mm including the slab thickness and column dimension of 300 mm x 300 mm. The dimensions of beam and column were made as 170 mm x 120 mm and 200 mm x 120 mm respectively. The length of the beam for the test specimen was 1200mm. The height of the column for test specimen was 1000mm.RC frame was cast, as bare frame. The RC frame was subjected to lateral load and the behaviour of frames was studied till failure.Important parameters such as capacity of frame, energy absorption and ductility were determined.
