Abstract - A comprehensive three-dimensional model of the RC buildings, including all structural and architectural details, is first created as part of the investigation. In order to find out how the structure reacts dynamically to seismic stimulation, ETABS software is used to do the response spectrum analysis. The response spectra that correlate to the site's location and the seismic hazard level that has been established are used in the study.
the pioneering skyscraper, setting the stage for other renowned landmarks such as the Eiffel Tower, the Empire State Building, and the Chrysler Building. The construction of record-breaking structures such as Taipei 101 and the Petronas Towers has been made possible by advancements in structural engineering. As the highest building in the world right now, the Burj Khalifa is a symbol of how far humans are willing to go in their quest for architectural perfection.
The use of belt and outrigger trusses improves the structural performance. These supplementary systems for lateral load resistance are positioned at appropriate heights throughout the building. The trusses improve the building's stability by reducing inter-story drift, redistributing lateral pressures, and supporting the structure. Material qualities, seismic characteristics, and code requirements are just a few of the design aspects that are considered during the process. By analysing the structure's response spectra, one may learn about its dynamic properties, such as its basic period, mode shapes, and spectral accelerations. Base Shear, Natural Period, Storey Stiffness, Maximum Storey Displacement, and Storey Drift are terms that come out of the study. The efficiency of the extra lateral load-resisting devices is evaluated by comparing the structures with and without the belt and outrigger trusses. Incorporating such truss systems improves structural performance under seismic loads, as shown in the research. Key Words: G+30, reinforced concrete (RC) structure, belt truss, outrigger truss, response spectrum analysis, ETABS, seismic loads.
1. INTRODUCTION Tall buildings have been around for a long time because people have always been interested in building things that reach new heights. An enduring example of the aweinspiring towering buildings built by ancient civilizations like the Mayans and Egyptians is the Great Pyramid of Giza. Impressive heights were shown by monumental and religious buildings in mediaeval Europe, such Gothic cathedrals. Nevertheless, the idea of skyscrapers came into existence in the 19th century, propelled by advancements in technology and the expansion of metropolitan areas.

1.1. Increase Performance of High-Rise Structure To enhance the performance of a high-rise structure, several key considerations should be addressed. Firstly, implementing advanced structural analysis techniques and materials is crucial to ensure optimal load distribution and resistance to external forces. This involves employing cutting-edge engineering technologies and materials with high strength-to-weight ratios. Additionally, incorporating intelligent design features such as damping systems and tuned mass dampers can effectively mitigate vibrations and sway, improving overall stability. Moreover, the integration of energy-efficient systems and sustainable technologies not only reduces operational costs but also aligns the structure with environmental standards.
