Abstract - In this study, the construction industry in India is
viable solution for both residential and commercial developments. Additionally, recent advancements have highlighted the significance of accounting for dynamic loads in structural design. Unlike static loads, which remain constant over time, dynamic loads—such as those generated by wind, seismic activity, or moving vehicles—fluctuate in intensity and direction. Addressing these forces requires sophisticated analytical techniques to maintain structural integrity. Methods such as modal analysis and time-history analysis enable engineers to assess how structures respond to varying loads. This dissertation investigates the performance of prefabricated buildings with different span configurations under both static and dynamic loading conditions, aiming to optimize structural efficiency and ensure safety in practical applications.
undergoing a significant transformation with the growing adoption of prefabricated building techniques. While conventional construction remains dominant, prefabrication offers notable advantages such as reduced construction time, improved quality control, and enhanced safety. This study focuses on evaluating the effectiveness of different spans in prefabricated buildings under varying static and dynamic loading conditions. Dynamic loading, which includes forces such as wind and seismic activity, has become a crucial factor in modern structural design due to its impact on building stability and safety. A comprehensive literature review reveals that most existing studies emphasize single-story or industrial prefabricated structures, often overlooking the influence of span variation under dynamic effects. Addressing this research gap, the present work aims to analyze the performance of prefabricated buildings across different spans and heights using structural analysis software. Both static and dynamic analyses are performed, considering variations in bracing systems to enhance structural response. The outcomes of this study include non-dimensional charts that correlate span effectiveness with building height, providing valuable design insights for engineers and architects. The findings support the feasibility of multi-story prefabricated construction and contribute to optimizing structural performance under realworld loading conditions.

Buildings and houses are essential to human life, and construction methods have evolved significantly since ancient times. Modern construction demands not only structural strength but also aesthetic appeal, speed, costefficiency, and quality. Pre-engineered buildings (PEBs) have emerged as a practical solution to meet these needs, offering faster construction and lower costs compared to traditional methods. To gain deeper insight into PEB design and performance, various research studies and journal articles were reviewed, with key findings summarized for reference.
The construction industry plays a crucial role in India's economic growth and has traditionally relied on on-site, conventional building methods. Recently, however, there has been a notable shift toward prefabricated construction, which is emerging as a more modern and efficient alternative. This approach involves producing building components in a controlled factory environment and subsequently assembling them at the project site. Such a method enhances quality control, accelerates construction timelines, and promotes better safety standards. With rapid urbanization and the increasing need for quick and reliable infrastructure, prefabricated structures are becoming a
