Abstract - This project aims to study the seismic
performance of the steel plate shear wall system in a (G+6) story building. The building drawings are prepared in AUTOCAD. Equivalent static analysis is carried out with the help of ETABS. For the shear wall, we are using a steel plate of 8 mm thickness, bounded by a beam of ISHB 550. Here we are studying various responses such as bending moment, story displacement, story drift, and shear wall stress.
To develop simplified models for the analysis of steel plate shear wall system using ETABS.
Study the behavior of building with steel plate shear wall.
Nowadays most Highrise buildings have RCC shear walls which under earthquakes are prone to more damage and are irreparable. Whereas in steel plate shear wall (SPSW), the steel plate tends to buckle and deform and dissipate energy. As a result, it can be easily replaceable.
Key Words: Steel plate shear wall, ETABS.
1.INTRODUCTION
3. METHODOLOGY
Engineers can do nothing but increase vertical development because the population is growing while the amount of available land is staying the same. As they got taller and thinner, tall structures were more vulnerable to seismic damage. An earthquake can be described as any kind of seismic event which may be either natural or initiated by humans, which generates seismic waves. Earthquakes are caused commonly by the rupture of geological faults; but they can also be triggered by other events like volcanic activity, mine blasts, landslides, and nuclear tests.[1]
1.1 Shear Wall Seismic load resisting systems are one of the many seismic mitigation strategies that have been advocated to lessen the damage. It improved the performance of the structure in the earthquake. Shear walls are frequently utilized in systems that resist the lateral load. A shear wall is a vertical structural element used to resist horizontal forces such as wind and earthquake forces. One of the breakthroughs in the steel plate shear wall.[2]

3.1 Geometric Characteristics
1.2 Steel Plate Shear Wall Steel plate shear wall known as SPSW consists of vertical infill steel plates with one bay length and one-story height. These infill plates are placed in all stories or selected stories and are connected to the beam-column boundary.[2]
