Although a common option where punching strengthening is concerned, few studies exist regarding how the bolt's anchorage dimensions and its embedment in the concrete slab affect the strengthening efficiency. This work presents an analytical approach that is able to predict the punching capacity of slabs strengthened with post\u2010installed vertical steel bolts, taking into account the anchorage dimensions and positioning plus the material properties. This approach results from the combination of two physical models: one provided in the <jats:italic>fib<\/jats:italic> Model Code for Concrete Structures 2010 regarding the punching capacity estimation, and another that allows the deformation (crushing) of the concrete beneath the head of the anchorage to be taken into account. The predicted values are compared with experimental results, showing that the analytical approach is able to simulate correctly the anchorage behaviour and its influence regarding a slab's loadbearing capacity. A parametrical analysis is carried out in order to study the importance of different factors such as concrete compressive strength, longitudinal reinforcement ratio and steel bolt length, always accompanied by the effect of anchorage head size and embedment.<\/jats:p>","DOI":"10.1002\/suco.201200051","type":"journal-article","created":{"date-parts":[[2013,10,15]],"date-time":"2013-10-15T08:19:26Z","timestamp":1381825166000},"page":"389-400","source":"Crossref","is-referenced-by-count":9,"title":["A physical approach for considering how anchorage head size influences the punching capacity of slabs strengthened with vertical steel bolts"],"prefix":"10.1002","volume":"14","author":[{"given":"Ricardo","family":"Silva","sequence":"first","affiliation":[]},{"given":"Duarte M.
