building categories to ensure safety and structural integrity.
and significant improvements in the fields of engineering and technology, high-rise structures are increasingly common. As the height of buildings increases, their response to seismic and wind loads also intensifies. According to Indian standard codes, the displacements and forces experienced by a structure are directly proportional to its height. Ongoing research focuses on mitigating these responses during extreme horizontal loading due to seismic activity and wind forces. One effective solution involves the use of passive control devices, such as various types of dampers, to manage and reduce the impact of these loads.
Seismic load is the horizontal force exerted on a building due to ground shaking during an earthquake. These loads are classified as "dynamic loads." Unlike other types of loads, which generally act slowly on a structure, seismic loads act rapidly and cause the structure to vibrate intensely.

Various types of loads act on reinforced concrete (RC) buildings. In India, the major loads considered are dead load, live load, seismic load, and wind load (for buildings taller than 10 meters, as per IS 875 Part 3). However, according to IS 456 Table 18, when considering the effect of earthquakes, the wind load is substituted by the earthquake load in the specified load combinations. This substitution reflects the prioritization of seismic effects over wind effects in structural design under earthquake conditions.
Dead Load:
Dead load is mainly caused by the individual weight of the structure and the completion of the structure. Dead loads are carried out only in the vertical direction. We can only assume that no tipping occurred due to static properties.
Live Load:
Live load in a building is due to occupants, furniture, vehicles, and other movable objects. The value of live load varies depending on the type of building, as specified in IS 875 Part 2. This standard provides guidelines for determining the appropriate live load values for different

Earthquake Load (Seismic load):
What is earthquake resistant building?
An earthquake-resistant building is designed to withstand various levels of seismic activity without significant damage. In a weak earthquake, no damage is allowed in structural members, and no major damage is permitted in non-structural members. During a moderate or moderately strong earthquake, some structural damage is allowed, but it should be repairable, and no major damage should occur. In a strong earthquake, major damage is allowed, but the structure must not collapse. This type of design ensures the building maintains its integrity and provides safety for occupants during and after an earthquake.
What is damper?
“Dampers are energy dissipation system”. Dampers are devices used to dissipate or absorb vibrations resulting from an earthquake, thereby increasing the damping and stiffness of a structure. These devices help to control and reduce the seismic response, enhancing the overall stability and safety of the building during seismic events.
