The purpose of this investigation is to determine the design loads for a structure that will be subjected to seismic loads in a specific area. It is well knowledge that seismic loads can be estimated in a certain zone using a zone factor. The seismic load of that zone can then be calculated depending on the magnitude of the earthquake and other characteristics unique to that region. However, Earthquake load is stochastic and time dependent. The structure should be constructed to meet the target demand for the duration of its life. The main goals of structural design are to create a structure that provides total resonance while maintaining safety in terms of strength, stability, and structural integrity, as well as acceptable serviceability in terms of stiffness, longevity, and cost. Key Words – Analysis and Design, Earthquake Resistant, Seismic Load, Stability, Stiffness, Staad Pro. INTRODUCTION – Seismic design for high-rise buildings has grown increasingly essential in recent years. For structures of small height subjected to low-intensity earthquakes, traditional methods based on the fundamental mode of the structure and the distribution of earthquake forces as static forces at various stories may be sufficient, but as the number of stories increases, seismic design becomes more rigorous. A design for a R.C.C building with a G+25 storey frame is being considered. The design is done with structural analysis design software (staad-pro). The structure was subjected to vertical as well as horizontal loads. The dead load of structural components such as beams, columns, and slabs, as well as living loads, make up the vertical load. The seismic forces make up the horizontal load, hence buildings are constructed for dead load, live load, and seismic load, according to IS 1893 - 2016. The structure is constructed as a two-dimensional vertical frame that is trial-and-error assessed for maximum and minimum bending moments and shear forces in accordance with IS 456-2000. The assistance is provided via software available at the institute, which allows for the computation of loads, moments, and shear forces. OBJECTIVES - The project's major goal is to improve knowledge of multistory RCC building structural design and architectural works. This project teaches us how to examine field difficulties and how to arrive at a reasonable solution, as well as refresh our knowledge of structural member design. Working in a real-world setting improves theoretical and practical knowledge, as well as confidence, which will be useful in professional activity in the near future. The following are the precise objectives of the project's work: 1. Identification of the plan's structural organization. 2. Determination of criticality and vulnerability in seismic performance. 3. Research into seismic codal provisions. 4. Use of Staad Pro to model the building for structural analysis. 5. Components are designed in sections. 6. Structural detailing for members. LITERATURE SURVEY 1. Vikrant Trivedi.et.el; (2018): This research compares wind loads in order to determine the design loads of a G+11 structure. The purpose of this investigation is to determine the design loads for a structure that is exposed to wind loads in a specific area. It is well knowledge that the wind load in a specific zone can be approximated using a zone factor. The wind load of that zone can then be calculated using the fundamental wind speed and other elements unique to that region. The wind velocity, on the other hand, is stochastic and time dependent.
