All opinions, findings, and conclusions stated in this paper are those of the authors and do not necessarily reflect the views of the supporting institutions.Unbonded post-tensioning (PT) monostrands have traditionally been used in buildings to sustain monotonic loads on members subjected mainly to gravity loads. As a result, most of the technical information on commercially available unbonded PT anchorage systems focused only on applications for gravity-loaded members. Despite the recent experimental research efforts on the behavior of PT anchorages under earthquake-simulated demands, this information has not been well quantified in design documentation. Consequently, further research is needed on unbonded PT anchorages for their use in members subjected to seismic loads. This paper presents the results of a comprehensive experimental evaluation on the ultimate capacity of monostrand anchorages subjected to high-amplitude concentric and eccentric cyclic loads. In addition, this paper addresses the influence of anchorage type, loading patterns and strand size on the ultimate deformation capacity of these anchorages. Specimens consisted of monostrands assembled with anchorages at both ends. Two types of anchorages were tested. Moreover, seven-wire, uncoated, low-relaxation PT monostrands in two sizes were considered. Several cyclic loading conditions were applied, in order to evaluate the behavior of anchorages under different scenarios. The ultimate capacity of the specimens was dominated by a premature fracture of one or few wires inside the wedges and two types of wire fractures were recognized: (1) with little reduction in the wire cross-sectional area and (2) with a notable reduction in the wire cross-sectional area prior the fracture. It was also observed that increased number of wire fractures correlated with larger strain capacity in some specimens. In addition, it was observed that eccentric loads reduced the strain capacity by about 18% for eccentricities of 6% in some cases. The fracture of the specimens occurred at relatively small strains, with values as low as 1.4%. Therefore, strains in unbonded post-tensioned strands should be limited to about 1.0% when designing for seismic loads. Furthermore, an analytical model was proposed to evaluate the influence of anchorages in unbonded post-tensioning precast structures.Consejo Nacional de Ciencia, Tecnología e Innovación Tecnológica - ConcytecengElsevier LtdEngineering Structuresinfo:eu-repo/semantics/openAccessWireAnchorages (foundations)-1Cyclic loads-1Fracture-1Joints (structural components)-1Seismology-1Strain-1Eccentric loads-1Inelastic strain-1Monostrand-1Posttensioning-1Strain capacities-1Structural design-1cyclic loading-1elasticity-1seismic design-1seismic design-1seismic response-1strain analysis-1structural analysis-1structural component-1tension-1https://purl.org/pe-repo/ocde/ford#2.01.04-1Evaluation of the behavior and ultimate capacity of unbonded monostrand-anchorage systems under concentric and eccentric inelastic cyclic loadinginfo:eu-repo/semantics/articlereponame:CONCYTEC-Institucionalinstname:Consejo Nacional de Ciencia Tecnología e Innovacióninstacron:CONCYTEC#PLACEHOLDER_PARENT_METADATA_VALUE##PLACEHOLDER_PARENT_METADATA_VALUE##PLACEHOLDER_PARENT_METADATA_VALUE#20.500.12390/605oai:repositorio.concytec.gob.pe:20.500.12390/6052024-05-30 15:22:25.835http://purl.org/coar/access_right/c_14cbinfo:eu-repo/semantics/closedAccessmetadata only accesshttps://repositorio.concytec.gob.peRepositorio Institucional CONCYTECrepositorio@concytec.gob.pe#PLACEHOLDER_PARENT_METADATA_VALUE##PLACEHOLDER_PARENT_METADATA_VALUE##PLACEHOLDER_PARENT_METADATA_VALUE#<Publication xmlns="https://www.openaire.eu/cerif-profile/1.1/" id="1a68909e-8669-4829-bb3c-0009dae46b87"> <Type xmlns="https://www.openaire.eu/cerif-profile/vocab/COAR_Publication_Types">http://purl.org/coar/resource_type/c_1843</Type> <Language>eng</Language> <Title>Evaluation of the behavior and ultimate capacity of unbonded monostrand-anchorage systems under concentric and eccentric inelastic cyclic loading</Title> <PublishedIn> <Publication> <Title>Engineering Structures</Title> </Publication> </PublishedIn> <PublicationDate>2018</PublicationDate> <DOI>https://doi.org/10.1016/j.engstruct.2018.09.036</DOI> <SCP-Number>2-s2.0-85053814008</SCP-Number> <Authors> <Author> <DisplayName>Bedriñana L.A.</DisplayName> <Person id="rp01197" /> <Affiliation> <OrgUnit> </OrgUnit> </Affiliation> </Author> <Author> <DisplayName>Zhang K.</DisplayName> <Person id="rp01198" /> <Affiliation> <OrgUnit> </OrgUnit> </Affiliation> </Author> <Author> <DisplayName>Nishiyama M.</DisplayName> <Person id="rp01196" /> <Affiliation> <OrgUnit> </OrgUnit> </Affiliation> </Author> </Authors> <Editors> </Editors> <Publishers> <Publisher> <DisplayName>Elsevier Ltd</DisplayName> <OrgUnit /> </Publisher> </Publishers> <Keyword>Wire</Keyword> <Keyword>Anchorages (foundations)</Keyword> <Keyword>Cyclic loads</Keyword> <Keyword>Fracture</Keyword> <Keyword>Joints (structural components)</Keyword> <Keyword>Seismology</Keyword> <Keyword>Strain</Keyword> <Keyword>Eccentric loads</Keyword> <Keyword>Inelastic strain</Keyword> <Keyword>Monostrand</Keyword> <Keyword>Posttensioning</Keyword> <Keyword>Strain capacities</Keyword> <Keyword>Structural design</Keyword> <Keyword>cyclic loading</Keyword> <Keyword>elasticity</Keyword> <Keyword>seismic design</Keyword> <Keyword>seismic design</Keyword> <Keyword>seismic response</Keyword> <Keyword>strain analysis</Keyword> <Keyword>structural analysis</Keyword> <Keyword>structural component</Keyword> <Keyword>tension</Keyword> <Abstract>Unbonded post-tensioning (PT) monostrands have traditionally been used in buildings to sustain monotonic loads on members subjected mainly to gravity loads.
