| Abstract | Tall buildings face challenges in windy or seismic areas. Shear wall-frame systems are common but costly. Concrete belt walls in flat slab-shear wall systems aim to improve performance. This study examines their impact in high wind and seismic regions using a 50-story building in Mandaluyong, Manila, comparing two models.A comparative study between the shear wall-frame system and the flat slab-shear wall with belt wall system has been proposed. The study focuses on high seismic and wind forces and initial design utilizes high wind analysis following ASCE 7-16 standards, with subsequent evaluation under Service-Level Earthquake (SLE) and Maximum Considered Earthquake (MCE) conditions. Various analysis methods, including Response Spectrum Analysis, Linear Time History Analysis and Nonlinear Static Analysis, compare base shear results to the Nonlinear Time History Analysis. The research underscores the importance of accurate modeling and acceptance criteria in seismic-prone regions.Furthermore, the nonlinear analysis shows the effectiveness of the belt wall in enhancing the global and local performance of the structure. Even though the results might not be clearly better than the wall-frame model, the belt wall still makes the structure remain in the range of acceptance criteria. From the analysis, the belt wall can be utilized to reduce the story height of the structure as well. |
