This paper presents the state of art of demolition techniques used worldwide, highlighting their impact and the advancements required for enhanced safety and efficiency. The study covers four primary demolition methods: wrecking ball, machine demolition, pulling and pushing with steel ropes, and simulated controlled demolition using explosives. As urbanization increases, so does the need for the safe and efficient demolition of structures that have reached the end of their service life or are no longer functional. Moreover, the urgency of controlled demolition is underscored by severe seismic events, which have necessitated the rapid and safe demolition of numerous non-earthquake-resistant structures in urban areas. Therefore, the study reviews current practices and offers research recommendations for progress. Recent innovations in numerical methods in mechanics of solid bodies, particularly the applied element method and finite element method (explicit nonlinear analysis), have significantly advanced the understanding of destruction mechanisms in large-scale structures similar to the methodologies explored in progressive collapse. Furthermore, a new approach for safely monitoring demolitions is introduced, utilizing stationary cameras or drones to capture and segment footages, track point displacements, and validate simulation results with real damage photographs. This comprehensive examination method enhances the accuracy of demolition simulations and ensures safer demolition practices. Overall, the paper provides insights for professionals and researchers in the field of controlled demolition, suggesting improvements to better understand the demolition mechanism.
