Applying Fixed Support in Model.
Supports are a crucial part of your structural analysis model.

Floor Diaphragms – Semi Rigid & Rigid Diaphragms
Rigid diaphragms have infinite in-plane stiffness properties, and therefore they neither exhibit membrane deformation nor report the associated forces, whereas semi-rigid diaphragms simulate actual in-plane stiffness properties and behavior. For most reinforced-concrete slab systems, in which the slab is sufficiently thick and membrane deformation due to lateral loading is negligible, rigid diaphragms produce results nearly identical to those of semi-rigid diaphragms, while taking advantage of faster computation. Semi-rigid diaphragms should be modeled when significant in-plane deformation does occur, or when required by code. Floor diaphragms can only be assigned to elements in the same X-Y (i.e. Horizontal) plane.

Earthquake Checks for Lateral Statabilty of the Building.
To ensure that a building can withstand loads (in this case, lateral forces of the ground as it shakes), structural engineers carefully design structural elements.
Earthquake loads are quantified and this value helps in determining the design lateral force the building has to resist; this is used to determine sizes of beams, columns, walls, and other structural elements. These lateral forces are often pretty large; to be able to design buildings that can resist these forces, itâ€™s essential for engineers to understand soil behavior. This is because the soil on which a building is constructed impacts the response of the building to the ground shaking. The softer the soil, the larger the lateral forces and vice versa. Engineers use several methods to determine the soil type and its nature

A soft story check.
A soft story check in ETABS is a stiffness irregularity check that can be performed to determine if a building level is more flexible than the stories above and below it. A soft story is a level of a building that has a lateral stiffness that is less than 70% of the stiffness of the story above it, or less than 80% of the lateral stiffness of the stories above it. This can lead to undesirable building performance, and in recent earthquakes, buildings with soft stories have sustained severe structural damage and collapsed.
