Comparative analysis of building with shear wall & diagrid structure

The rapid growth of urban population, the lack of spaces in the cities and the high cost of land have already forced the developers to focus on the high-rise buildings. As the height of the building increases, the lateral load resistant system become more important than gravity load resistant system. That’s why it is important to define lateral load resistant system in high rise buildings. So the lateral load resistant systems such as shear wall and diagrid are introduced since they are better in terms of cost, aesthetic and performance. However, the diagrid structural system has become more popular these days due to its efficiency and aesthetic look provided by the unique geometric configurations of the system.

In this study, a comparative analysis has been done on the buildings with different lateral load resisting systems. Five different building model of G+9 story building has been modeled with shear wall and diagrid structure to compare their performance. The design is analysed for seismic zone V and medium soil condition as per IS 1893:2016 using ETABS software. The building is kept the same except for the lateral load resisting system. From the patterns of the results, it was concluded that building models with the combination of shear wall and diagrid module has better performance in term of the maximum story displacement, story stiffness, story drift, base shear, and time period.
