---------------------------------------------------------------------***--------------------------------------------------------------------1.1 Bracing Abstract - Steel-concrete composite-structures are important in modern building because of their synergistic benefits. These constructions provide outstanding load carrying capacity, structural efficiency, and design flexibility by combining the high tensile strength of steel with the compressive strength of concrete. They are resistant to dynamic loads such as earthquakes and wind forces, making them excellent for resilient and safe construction. So when compared to RCC Structures, steel concrete composite -structures are being more-popular. In this paper, an-attempt was made to evaluate and compare the performance of G+25 storey’s RCC and Composite- Structures subjected to seismic-load using ETABS 2020 Software. A total of six models were prepared, 3 models are of RCC and 3 models are of composite buildings, in which lateral load-resisting systems, such as bracings and shear walls are installed. The buildings-are located in seismic zone-V and soil is medium. Response-spectrum Analysis is used for both RCC and Composite-Structures. Displacement, StoreyDrift, Base-shear and Time Period are considered as parameters. When compared to RCC, composite structures performed better.
A Bracing system is a structural element to resist lateral forces like-wind, and other loads that can cause the building to sway or collapse.

1. INTRODUCTION The seismic-performance of structures is a crucial factor in structural engineering, especially in earthquakeprone areas. The choice of building materials and construction techniques has a big impact on how resilient a structure is to seismic pressures. Seismic resilience of structures is a major challenge in earthquake-prone areas. Because of their various characteristics and engineering properties, reinforced concrete (RCC) and compositestructures have emerged as two key competitors for withstanding seismic loads.

Composite constructions combine the advantages of many materials to improve performance. They often involve the combination of concrete with steel or other highstrength elements. This combination improves structural efficiency by allowing the structure to benefit from the strengths of each constituent material. Composite-structures have higher rigidity and ductility than typical RCC structures.
