Zielsetzung und Themenschwerpunkte (Objectives and Key Themes)

The primary objective of this report is to investigate the dynamic behavior of a building structure designed for the looms industry, particularly focusing on the impact of vibrations generated by the looms machines. The study aims to understand how varying the sizes of structural components like beams and columns affects crucial dynamic parameters such as frequency and amplitude. Additionally, the report explores the effectiveness of various remedial measures, such as cross-bracing, jacketing, tie-beams, and haunches, in mitigating resonance conditions and improving the overall performance of the building structure.

• Dynamic analysis of structures in the looms industry
• Impact of machine-induced vibrations on structural performance
• Parametric study on the effects of structural component sizes
• Evaluation of remedial measures for vibration control
• Assessment of resonance conditions and their mitigation strategies
