To Model a RC residential structure using TSD
Above Screenshot shows that " Summation of first three modal frequency constituting modal mass greater than 90% of Modal Mass.
2. Difference b/w first three Fundamental Natural frequency in three principal direction differ by more than 10% of Fundamental Natural Frequency in Direction1.
This show that " There is no irregular modes of vibration in this model."
First Floor Layout Plan
Centre of Rigidity is shown by Red Colour in above screenshot.
Center of Mass is shown above by this colour.

At Mummy level, two points are coinciding to each other as shown in above screenshot.

Layout Plan of Column :
Column at Grid (D4 & D3) only are of dimensions ( 300*450)mm, while
Rest of the Columns are of (450*450)mm.
================================================================================
all Beams consist of (300*600) mm configuration while beams under stair case plan are of (300*450)mm.
Rest of the modal frequency corresponding with modal participation Factor is shown in Excel fiile attached under.

Deflection Dia. under vertical deflection: serviceabiliy criteria
================================================================================
As this model is nearly 10m height, therfore Lateral Load application is not of much consideration, even after Screenshots of Drift in two directions are represented below:
Deflection along the width of the building (i.e. along Y axis)
===========================================================================
Deflection Diagram in X axis along the length of the building.
