Review of IS 1893-1(2002): Effect of Unreinforced Masonry Infill Walls on Seismic Response of Framed Structures
Earthquake, its occurrence and effects, its impact and structural response have been studied for many years in earthquake history and is well documented. The structural engineers have tried to examine the various method, with an aim to determine the complex dynamic effect of seismically induced forces in structures, for designing of earthquake resistant structures in a advanced and easy manner. From the study conducted it was found that more precise results are found from nonlinear static analysis method. An overview of the past researches conducted on the modelling of masonry infilled frame issues, it was found that macro model which consider the effect of masonry weak links is used for modelling the infill panels. Different factors governing the period of vibration was checked, and the result shows the effect of stiffness of the building is the most important factor influencing the period of vibration. Parametric study was conducted to determine the most influential factor that affects the period of vibration of a structure. From the observations it was clear that the effect of stiffness is the most important factor influencing the period of vibration. Therefore a curve with dimensionless height and lateral displacement were plotted using nonlinear static analysis obtained from SAP2000. From the above mentioned curve, the effective stiffness of the building under consideration is calculated, which route to find the period of vibration of the structure that is considered for the seismic analysis [1].
