“…There are many types of systems available to reduce these ground motion. Structural isolation method, active control system, passive control system to name a few [1][2][3][4]. Energy dissipating devices are effective but may increase the cost in any structure, various structures all around the globe are using these methods with a view of increasing the structures resistance towards ground forces and wind forces with an aim of reducing vibration [5][6][7].…”

Earthquakes can be devastating for cities due to mid and high-rise buildings, as these structures are vulnerable to shaking due to earthquake forces. The effects of earthquake magnify when buildings are constructed with plan or elevational irregularities. To address this issue, in this study, building models with plan and vertical irregularities are analyzed using nonlinear time history analysis. Further, uid viscous dampers are designed for both types of buildings using Performance based methodology. The response of buildings during seismic events for all models with plan and vertical irregularities is checked with and without dampers. The storey displacements, base shear, element forces and energy dissipation of dampers is compared for the various time history earthquake records. It was observed that, the design of uid viscous damper changes drastically when irregularities comes into picture. Also, an increase in base shear, axial force values while decrease in storey displacement, shear forces, bending moment values was observed due to inclusion of dampers. It is found that the dampers in structures are effective in resisting earthquake forces.

“…Moreover, the need for developing fragility models that account for soil-structure interaction and specific structural and ground conditions, data gathered from Mexico-Puebla 2017 earthquake has also been studied (Román-De La Sancha et al, 2019) to ensure a more reliable risk characterization. The efficient placement of friction dampers on building structures with and without the effects of soil-structure interaction has also been executed (Sanghai & Pawade, 2019, Sanghai & Pawade, 2021, Bagchi et al, 2021. Nonetheless, the consequences that the local site effects might have on the performance of friction dampers have been overlooked.…”

The local site conditions and the geological properties of soil materials on which buildings are constructed might play a pivotal role in changing the characteristics of input seismic ground motions, and subsequently affect the seismic performance of the structures. These effects should be considered in the seismic evaluation of structures, especially those equipped with damping devices. As a matter of fact, these devices are designed to increase the energy dissipation capacity of the buildings through certain inelastic mechanisms, which are highly dependent on the input ground motions. Friction dampers are one of the cost-efficient controlling devices in which whose performance mostly depends on the story displacements. Hence, the variation in seismic excitations caused by the local site effects might have an impact on how they mitigate the earthquake hazard in addition to their efficiency. Shedding light on the above facts, this paper evaluates the influence of site effects on the seismic performance of a 10-story intermediate friction-damped steel moment frame under near-field excitations. Nonlinear timehistory analyses are done using ten ground motions, which have been originally recorded at bedrock, while variation in their properties is calculated by passing them through a soil profile, which is modelled using the equivalent linear method. The result indicates that considering the site soil effects has a major consequence on ground motions as well as the performance of dampers insofar as it leads to a rise in the amount of input energy and the story drifts. Nevertheless, the seismic performance of the dampers remain quite efficient and reliable. D D

“…Gandelli et.al [9] retrofitted hospital building. Sanghai et.al [13] studied the available literature on combine effect of soil structure interaction and friction dampers and put forth effectiveness of friction dampers changes as soil condition changed. Wang et.al [10] upgraded 35 storeys steel moment-resisting frame by using three different dissipation devices and found none of them performs best under seismic consideration.In this paper attempt is made to seismic retrofit the reinforced concrete (RC) frames by use of performance based design of friction dampers.…”

India suffered from many earthquakes over last some decades. Analysis of those earthquake showed that large number of existing structures needs to be upgrade for seismic actions. Performance based earthquake engineering is recent focus of researchers. Present study focused on the seismic retrofitting of existing structures which are previously designed for gravity loads only, by using performance based design philosophy of friction damper. Storey displacement, inter-storey drift, axial force, maximum moment, maximum shear force, base shear variation and effectiveness of dampers are observed for each model and in each direction for seven records of time history earthquakes. Results showed that response of structure are well within the limits of codes provisions. Thus friction damper can be used effectively for seismic retrofitting of structures.Keyword -Retrofitting, Pushover analysis, Friction damper, Time history analysis, Inter-storey drift. I. INTRODUCTIONEarthquake is natural disaster phenomenon in which the motion of the tectonics plate under the earth crust causes the ample amount of energy to be liberated in the form of vibrations. Earthquakes are highly unpredictable and occur suddenly without any prior warning. Approximately 50,000 earthquakes occur in a year over the globe. During the earthquake large amount of energy is transmitted into structure which causes the damage to structures. Amount of damage is depends on pattern by which the energy gets transferred in the structure. India has series of earthquake history, Koyana earthquake strikes the koyana dam with magnitude 6.5 at 10 december 1967, causes 200 peoples deaths and 1500 injuries. Nepal and Bihar earthquake with magnitude 6.6 leads to 1004 people deaths and 16,000 injuries and lots of structural damage. Utterakshi earthquake (1991) of a magnitude 6.6 with PGA as 0.31g, causes 768 deaths and 5066 injuries. Several structures were damage with RC frame and load bearing. Mainly brick infill was damage and slabs got cracked. 30september 1993 killari earthquake with intensity of VIII, more than 30% population was suffered from impact of earthquake. Bhuj earthquake (2001) at Gujrat occurred on 26 january 2001 of magnitude 7.7, destroyed nearly 400000 structures. Divesting effect of earthquake leads to develop and modify the earthquake design codes, which demands higher ductility requirements for safety of the structures. Day by day modification made under code, leads to that the structures become vulnerable which was designed by previous code. Such structures need the retrofitting for updated structural requirement.India has population nearly 130 corers which creates the pressure on government agencies for fulfilment of their basic needs such as shelter, food, health services, and educational services. All such services needs infrastructure such as house for shelter, hospitals for medical services and schools for quality educational services. Large investment is concurred for developing infrastructure facilities so it becomes very important to increa...
