Abstract

This study examines the response characteristics and damage mechanisms of masonry wall structures subjected to multi-cloud explosion conditions, emphasizing structural vulnerability and risk under explosive loads. Through numerical modeling and experimental analysis, pressure, displacement, stress, and damage distribution are investigated across various explosion regions. The results indicate that the complex partitioning of over-pressure fields in multi-point cloud explosions leads to distinct response patterns in single-peak wave zones, multi-peak wave zones, and Mach zones. In the single-peak wave zone, the over-pressure peak reaches 0.4 MPa with minor oscillations, while the multi-peak wave zone exhibits a complex pressure pattern with intensified impact. The Mach zone is characterized by pronounced Mach reflection effects. Additionally, the study identifies damage patterns in masonry walls positioned at the periphery of the cloud zone and under single-point cloud explosion conditions, providing valuable insights into blast-resistant design and structural safety assessment.
