Abstract

Construction sites are one of the most dangerous workplaces because of the variety of hazards and according to the procedure in which they are classified as hazardous work sites and mortality in construction sites with a large distance is among the most important causes on the list of occupational deaths. Safety is changing as a concept and method of coping with the risks to protect the lives of people and prevent damage as it the beginning of process. In this study, 15 story structure has been modeled and in 8 blast models by applying high heat to the columns, this modeling has been completed. The demolition of the upper floors does not lead to the destruction of the lower floors. Destruction of corner columns will destroy the whole structure and also it will cause the deflection of it, and the blast is better if it is symmetrical. An asymmetry in the loading does not affect the structure to exit the centrality. The destruction of the middle and bottom columns is suggested for the progressive failure of the best state
