Comprehensive experimental and numerical studies are carried out on the dynamic characteristics of 3 dimensional (D) reinforced Concrete (RC) frame with Masonry Infill (MI). MI though considered as non-structural element largely affect strength, stiffness and ductility of the framed structure during the application of lateral loads such as wind and earthquake loads. This paper is a part of a collaborative research project between CPRI and BARC focusing on the influence of MI on the natural frequencies of 3D RC frame and comparison of the results with the design codes. A 3D RC frame having two bays and three storeys is designed and detailed as per the relevant Indian standard codes. A simple numerical model is being formulated to obtain the natural frequencies in the FE analysis and Tri-axial shake table of 3m × 3m is used for the experimentation. The details of the numerical analysis and experiments carried out in the research work are brought out in this paper.

Abstract


Comprehensive experimental and numerical studies are carried out on the dynamic characteristics of 3 dimensional (D) reinforced Concrete (RC) frame with Masonry Infill (MI). MI though considered as non-structural element largely affect strength, stiffness and ductility of the framed structure during the application of lateral loads such as wind and earthquake loads. This paper is a part of a collaborative research project between CPRI and BARC focusing on the influence of MI on the natural frequencies of 3D RC frame and comparison of the results with the design codes. A 3D RC frame having two bays and three storeys is designed and detailed as per the relevant Indian standard codes. A simple numerical model is being formulated to obtain the natural frequencies in the FE analysis and Tri-axial shake table of 3m × 3m is used for the experimentation. The details of the numerical analysis and experiments carried out in the research work are brought out in this paper.
