The investigation will involve the creation of geometric models of two buildings one exhibiting rotational symmetry and another lacking such symmetry. These models will be subjected to various loading conditions, and their structural responses will be analyzed using ETABS, a popular program for structural design and analysis. By comparing the behavior of these structures, we aim to discern the effect of rotational symmetry on structural performance and identify any significant differences in behavior attributed to symmetry considerations
urbanization and economic growth, a large demand is created on innovative constructions, in this paper a comparative analysis and influence of rotational symmetry on the structural behavior of buildings using ETABS software. Rotational symmetry structures are examined to determine how it affects load distribution, stiffness, and overall stability in building structures. Two geometric models one with rotational symmetry and another without are subjected to various loading conditions, and their structural responses are analyzed. Findings show that rotational symmetry can significantly affect structural behavior, with implications for both aesthetic and functional aspects of building design. This research contributes to advancing knowledge in architectural and structural engineering, offering valuable insights for practitioners seeking to enhance the performance and visual appeal of building structures.
This study is expected to contribute to corpus of information in architectural and structural engineering by shedding light on the mutual influence between symmetry and structural behavior in building design. The findings may inform design practices, allowing architects and engineers to leverage rotational symmetry as a tool for enhancing both the structural integrity and visual harmony of buildings.

1.1 HORIZONTAL/PLAN IRREGULARITY When it comes to building design, there's a tricky concept to consider: horizontal irregularities. These are basically differences in how weight, strength, or stiffness are spread out across a building's floors. They can mess with a building's stability and safety. In this paper, we're going to dig into what these irregularities are, how they affect buildings, and what we can do about them. By blending ideas from both building design and engineering, we hope to make it easier for architects and engineers to deal with these challenges.
1.INTRODUCTION In the realm of architectural and structural engineering design, symmetry has long been regarded as a fundamental principle contributing to both aesthetic appeal and structural efficiency. While axial and bilateral symmetries are commonly explored in architectural compositions, the potential impact of rotational symmetry on structural behavior remains an intriguing area of investigation. Rotational symmetry, characterized by repetitive patterns around a central axis, presents unique challenges and opportunities in building design and analysis.

This paper aims to explore the affect of rotational symmetry on the structural behavior of buildings through a comparative analysis utilizing ETABS software. By systematically examining buildings with and without rotational symmetry, we seek to elucidate the role of symmetry in governing structural performance, including load distribution, stiffness, and overall stability. Through this analysis, we endeavor to provide valuable insights for architects and engineers in optimizing the design and functionality of the architectural structures

a) The walls and columns are as strong as their necessity to be where the weight is. b) The floors are strong and not too big. But if: One end of a floor moves a lot more sideways than the other. It takes longer for building to twist than to move side to side, Then, it's called twisted or torsion.
