This research also intended to assess both ultimate capacity and adequate serviceability of the local anchorage zone when reducing the concrete cross section and the confining reinforcement, both specified by the anchorage device supplier, by using an HPFRC. The experimental program included ORC prismatic specimens with 305\u2009mm\u2009\u00d7\u2009305\u2009mm\u2009\u00d7\u2009650\u2009mm reinforced with spirals and a combination of spirals and stirrups, and HPFRC specimens with 210\u2009mm\u2009\u00d7\u2009210\u2009mm\u2009\u00d7\u2009420\u2009mm reinforced with stirrups. The reinforcement steel strains were measured to monitor the steel yielding, to assess the relation between the strains of the inner (spiral) and outer (stirrups) levels of reinforcement and the uniformity of the confinement forces along the confined length. A comparison between the bearing strength obtained by experimental tests and by models found in the literature is also presented. From the strain measurements, it can be concluded that in the case where there are, simultaneously, two types of confinement reinforcement, the outer reinforcement is not as effective as the inner one. Therefore, when computing the bearing strength, the linear superposition of contributions of both spiral and stirrups for confinement can be nonconservative, leading to too high estimated load capacity.<\/jats:p>","DOI":"10.1002\/suco.201800238","type":"journal-article","created":{"date-parts":[[2019,1,9]],"date-time":"2019-01-09T07:28:43Z","timestamp":1547018923000},"page":"1182-1198","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":20,"title":["Efficiency of the confinement reinforcement in anchorage zones of posttensioning tendons"],"prefix":"10.1002","volume":"20","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3576-5690","authenticated-orcid":false,"given":"Carla","family":"March\u00e3o","sequence":"first","affiliation":[{"name":"Civil Engineering Department, Faculty of Sciences and Technology Universidade NOVA de Lisboa  Caparica Portugal"}]},{"given":"V\u00e1lter","family":"L\u00facio","sequence":"additional","affiliation":[{"name":"CERIS, Civil Engineering Department, Faculty of Sciences and Technology Universidade NOVA de Lisboa  Caparica Portugal"}]},{"given":"Hans R.","family":"Ganz","sequence":"additional","affiliation":[{"name":"Ganz Consulting  B\u00f6singen Switzerland"}]}],"member":"311","published-online":{"date-parts":[[2019,1,8]]},"reference":[{"key":"e_1_2_7_2_1","unstructured":"BreenJE FenvesG BurdetO.
