Study of Dynamic Properties of Building with Varying Plan Area and Height

In this topic Effect of height of building on time period natural frequency and mode shapes are evaluated by using ETABS software. For this purpose response spectrum method is taken into consideration and results are obtained in ETABS. The study includes the modelling of two buildings having plan areas 15 m x9 m and 25mx15m and the height is varied from G+3, G+6, G+9 and G+12 storey. The study is conducted by varying the geometrical properties of the structure but the seismic properties are kept constant. The buildings are located in zone III region. Spring mass model with the lateral forces are also plotted for the different buildings. Variation in bending moment and shear force are also evaluated.
