The approach followed in this study consists of a mathematical model based on the centre of mass of the human body, the inertia of a person in motion and the human gait speed. Moreover, the study includes the representation of a building using graph theory and emulates the presence of a person inside the building when an emergency takes place. The optimal evacuation route is obtained using the breadth-first search (BFS) algorithm, and the evacuation time prediction is calculated using a Gaussian process model. Then, the risk of the building is quantified by using a non-sequential Monte Carlo simulation. The results open up a new horizon for developing a more realistic model for the assessment of civil safety.<\/jats:p>","DOI":"10.3390\/s20102899","type":"journal-article","created":{"date-parts":[[2020,5,20]],"date-time":"2020-05-20T10:37:38Z","timestamp":1589971058000},"page":"2899","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Body Mass Index in Human Gait for Building Risk Assessment Using Graph Theory"],"prefix":"10.3390","volume":"20","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3999-9769","authenticated-orcid":false,"given":"Washington","family":"Vel\u00e1squez","sequence":"first","affiliation":[{"name":"Escuela Superior Polit\u00e9cnica del Litoral, Campus Gustavo Galindo Km 30.5 V\u00eda Perimetral, P.O.
