This study aims to examine the efficacy of a Tuned Mass Damper (TMD) in reducing the vibrations, encompassing both frequency and amplitude, of a high-rise structure. The procedure was executed utilizing Ansys Workbench (Design Modeler, Mechanical). The evaluations conducted included Modal Analysis and Harmonic Response assessments for both the building independently and in conjunction with the TMD. The TMD shown efficacy in diminishing the peak amplitude and its associated frequency of the structure.

This study aims to analyze the impact of wind on two distinct structures—one constructed of steel and the other of concrete—when subjected to varying wind angles. We utilized ANSYS Workbench to evaluate the structural response of these buildings during wind exposure at angles of 0°, 45°, and 90°. We employed modal analysis to determine the natural frequencies and mode shapes of both structures, followed by static and harmonic response evaluations to assess their deflection, stress levels, and safety under wind pressure. The objective is to evaluate the response of the two materials to wind originating from various directions. The findings indicate that the steel structure exhibits superior wind resistance, characterized by enhanced flexibility and safety, whereas the concrete structure is more rigid but has a greater propensity for failure at specific wind angles.

This study aims to evaluate the dynamic response of two buildings with different heights and materials—one a taller steel structure and the other a shorter concrete structure—under wind-induced harmonic loading using ANSYS Workbench. Modal analysis is conducted to identify natural frequencies and mode shapes, while harmonic response analysis assesses behavior under a 50 MPa wind load. The objective is to assess how material composition and geometric differences influence structural performance and resilience under dynamic wind loading. The results indicate that the steel building exhibits better dynamic performance and higher safety margins compared to the concrete building under wind-induced excitation.

This article conducts a Response Spectrum Analysis (RSA) of a G+3 reinforced concrete framed structure utilizing STAAD Pro. The natural frequencies for the initial three vibration modes, total base shear, inter-story drift ratios, and roof-level displacement are extracted and analyzed. The RSA is performed in accordance with IS 1893:2016 (Part 1) for Seismic Zone V, utilizing medium soil, an importance factor of 1.0, a response reduction factor of 5.0, 5% damping, and CQC combination methodology. The findings indicate that the initial three natural frequencies are 2.933 Hz, 5.056 Hz, and 9.372 Hz, the cumulative base shear is 243.86 kN, and the maximum roof displacement is 4.050 mm. These values offer insight into the building's dynamic performance.

This project presents the structural analysis of a G+7 reinforced concrete (RC) framed building located in Ahmedabad, which lies in Seismic Zone III as per IS 1893 (Part 1):2016. The building is modeled and analyzed using STAAD.Pro CONNECT Edition to evaluate its performance under seismic and wind loading. The total height of the building is 26.365 meters, including a foundation depth of 1.524 meters and floor heights as per architectural design. The structure is designed with Special Moment Resisting Frames (SMRF) to ensure ductile behavior during seismic activity. Dead loads such as floor finish, slab, and terrace loads are included based on IS 875 (Part 1):1987, with values like 5.75 kN/m² for floor slabs, 6.5 kN/m² for the terrace, and 15 kN/m² for the water tank. Live loads are considered as 2.0 kN/m² on typical floors, 1.5 kN/m² on the terrace, and 8.64 kN/m on landing beams. The structure consists of 0.45 m × 0.30 m beams, 0.30 m × 0.23 m plinth beams, and 0.60 m × 0.30 m columns. Wind load is applied based on a basic wind speed of 39 m/s as per IS 875 (Part 3):2015. Seismic analysis is carried out using the response spectrum method with a zone factor of 0.16, importance factor of 1.0, and response reduction factor of 5. The results show that the first three natural frequencies are 1.099 Hz, 1.593 Hz, and 3.004 Hz. Maximum base shear values are 201.61 kN and 195.83 kN in the X and Z directions respectively. The building shows a maximum storey drift of 10.99 mm at the fifth storey and a top displacement of 39.46 mm in the X direction, all within IS 1893 permissible limits. This confirms the structure’s adequate seismic and wind performance.
