Seismic Analysis of Steel Diagrid Structures Using Triple Friction Pendulum Isolator (TFP)
Today new technique of construction as well as aspect of design is coming to forefront as method of conventional design has failed to give the proper result. Base isolation is one of the most widely accepted seismic protection system used in earthquake prone areas. The base isolation system separates the structure from its foundation and primary moves it relate to that of the super structure. Diagrid structure is new trending concept in the field of structural engineering taking into account the factors of structural stability, aesthetic appearance and economic consideration. The scope of the paper is related to the seismic analysis of steel diagrid structure in combination with base isolation. Here Triple Friction Pendulum Isolator is used for base isolation. Dynamic linear response spectrum analysis and dynamic linear time history analysis is performed in the isolated diagrid building. Further a comparative study of performance of base isolated diagrid building has been carried out by response spectrum and time history analysis by changing the bracings and bracing arrangement pattern. i.e., X, V, inverted V, eccen forward and eccen backward bracings in whole, alternate, horizontal and vertical pattern arrangements. For this a 22 storey and 11 storey steel diagrid building is designed and the above mentioned analysis is carried out. Base shear and top storey displacement are used as parameters for this study. From the results it concluded that for both 22 storey and 11 storey diagrid building, building having V bracing with alternate arrangement pattern showing better results.
