The functional requirements and structural safety of a structure can be obtained from building laws, building codes and by adopting appropriate design methods. But in a developing country like India, the economy of construction is also of major importance. A frame system becomes structurally less efficient when subjected to large lateral loads such as a strong wind, earthquake or explosion. The situation becomes worse when the structural height is increased. In the current study the focus is on the investigation of the effect of infill in building and their behaviour in structure. There are different types of infill materials used in buildings, like brick infill, AAC block infill, Hollow concrete blocks infill etc. In this study focus is on behaviour of structure with different types of infill materials used. In this study four different types of model used- (1) RCC frame taking infill masonry weight, neglecting effect of stiffness. (2) Effect of stiffness is considered in addition to taking weight of infill (3) (Effect of stiffness is considered in addition to weight of infill excluding soft ground storey (4) (Effect of stiffness is considered in addition to weight of infill including soft ground storey effect. For each infill four cases studied. In this study three types of infill material used first is brick infill, second is AAC block infill and third is Hollow concrete block infill. So there for three types of infill material in which models have been prepared in ETABS. In this study 10 storey building is considered for analysis which is located in zone 4 earth quake region. Static analysis is done using ETABS software, soil conditions are to be medium and importance factor is to be taken as 1.2. Various parameters studied like lateral displacement of building, axial load in column, storey drift, storey shear, base shear, and moment’s diagrams for a particular beam for all three types of material a nd for all four cases. Results are represented in graphical as well as in tabular form. The structural members are modelled with the ETABS software package. Rigid end conditions are assumed for the frame members and the floor slab is assumed to act as diaphragms which ensure integral action of all the lateral load-resisting elements. The floor finish is taken to be 1.5 kN/m2 on the floors. The live load on floor is taken as 2 kN/m2. In the analysis, 25% of the floor live load is considered in seismic weight calculations as per code IS 1893:2002. Key Words: Soft storey, masonry infill, RC frame, earthquake, displacement, drift, base shear AAC blocks, Hollow concrete blocks. 1. INTRODUCTION 1.1 Introduction Reinforced concrete structures with masonry infill’s are very common type of construction in India. Masonry walls provide good architectural finish as well as it is quite useful with functional point of view. They are considered to be nonstructural elements. It is considered that these in fills do not have bonding with the frames in the design. Although an infill panel interacts with the frame when it is subjected to the lateral forces. As per now a days designs for the calculations of the seismic behavior of the RC frames the infill are not considered as their structural part and only as a load providing element but this leads to an inaccurate results and hence actual seismic behavior of structure is not guessed properly. The infill walls could be filled with various elements some of them are conventional bricks, AAC blocks, solid concrete blocks, hollow concrete blocks etc. Still this field has to go through a lot of study and research to understand properly the use of the various infill. In present study focus is about the response of various infill to the seismic activities. Hollow concrete, AAC blocks, and clay bricks have been used as the infill in the RC frames. AAC blocks are light- weight building material and provide insulation and fire resistance; they also have lower impact on the environment. Hollow concrete blocks are also very light weight but not light as AAC blocks .Hollow concrete blocks provide much better insulation to the building and is a good material to construct a green structure. The experimental results have shown that the hollow concrete blocks infilled RC frame exhibits better performance subjected to lateral loads than that of AAC and conventional bricks infilled frames. Infill materials improve the performance of the RC frame structures as they somehow participate in frame structural part also. An infill wall decrease lateral deflections, storey drift, and the bending moment in the frames, and it also increase the axial loads in the columns hence the possibility of collapse of the structure decreases.
