Abstract

This study explores the integration of low-cost earthquake-resisting techniques into regular building structures, focusing on the implementation of mass irregularity, bracing systems, and belt walls. Regular structures, while efficient in design, can be vulnerable to seismic forces, necessitating affordable and effective methods to enhance their resilience. The research investigates how introducing mass irregularity can modify the dynamic characteristics of a building, potentially reducing its susceptibility to seismic damage by altering natural frequencies and modes of vibration. Bracing systems, known for their simplicity and effectiveness, are analyzed for their ability to improve lateral stability and reduce inter-story drifts, making them a viable option for seismic reinforcement. Belt walls, which act as horizontal diaphragms, are also examined for their effectiveness in redistributing seismic forces across the structure, thus reducing localized stress concentrations and improving overall structural integrity. Through a combination of analytical modeling and comparative analysis, the study assesses the performance of these techniques in various seismic scenarios. The findings highlight the potential of these low-cost solutions to significantly enhance the earthquake resistance of regular buildings, providing valuable insights for engineers and architects working in earthquake-prone regions, particularly where budget constraints limit the use of more advanced seismic mitigation technologies. The research contributes to the development of practical, cost-effective strategies for improving the safety and resilience of regular structures in the face of seismic hazards. The study proves the idea that cheap earthquake resisting strategies can have considerable influence on seismic behavior of usual structures. Belt walls prevent lateral displacement the best, enhance storey-stiffness, and decrease bending moments and axial forces, and will play a major role in enhancing stability of the structure. Bracing systems are very useful in reducing shear and mass irregularity is efficient in countering torsion but it has more lateral movements. It goes to suggest that there is great potential in the application of low-cost means of increasing seismic resilience, in appropriately built structures that provide cost-effectiveness in terms of safer building design.
