A finite element based numerical model is developed in ABAQUS for tracing response of UHPC beams throughout the loading range; from preloading to collapse stage. The model accounts for detailed stress strain response of UHPC in both compression and tension and strain hardening effect. Response parameters generated from the model namely deflections, crack propagation, and failure mode are validated against measured data from experiments on UHPC beams. The developed model is applied to study the response of beams with varying shear reinforcement ratio to explore the feasibility of eliminating stirrups in UHPC beams. Results indicate that unlike conventional concrete beams, UHPC beams perform well under dominant shear loading even when no stirrups are provided. In other words, eliminating stirrups does not result in reduction of ductility and load carrying capacity of UHPC beams.","PeriodicalId":170570,"journal":{"name":"Second International Interactive Symposium on UHPC","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124932887","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Evaluation of UHPC as a Repair Material for Corroded Steel Bridge Girders UHPC作为腐蚀钢梁修复材料的评价

{"title":"Evaluation of UHPC as a Repair Material for Corroded Steel Bridge Girders","authors":"K. McMullen, A. Zaghi","doi":"10.21838/uhpc.9641","DOIUrl":"https://doi.org/10.21838/uhpc.9641","url":null,"abstract":"Corrosion damage of steel girder ends is a prevalent problem throughout the United States. This damage is often caused by leaking expansion joints, which deposit water and chlorides on the girders. Section loss at these critical locations can be detrimental to the bearing capacity of the girder. Current repair methods are costly, time consuming, and disruptive to traffic. A new repair method has been proposed by the University of Connecticut and the Connecticut Department of Transportation using ultra-high performance concrete (UHPC) to repair these corroded steel girder ends. The repair consists of welding headed shear studs to the undamaged portions of the web and encasing the girder in UHPC. The shear studs provide an alternate load path from the girder to the UHPC panels to bypass the corroded region. A series of full-scale 54-in. (1.37-m) deep plate girder specimens were tested to evaluate the load-carrying performance of the UHPC repair with different panel heights, stud layouts, and UHPC materials. The experimental program included a baseline corroded girder with no repair and three corroded girders repaired with UHPC. Conventional forming and casting techniques were used for each of the repairs in order to establish standard procedures that could be adopted for field implementation. One of the girders was exposed to simulated service-level vibrations during curing to demonstrate the ability to implement the repair without interrupting traffic. The results show that the UHPC repair presents a viable option for restoring the load bearing capacity of damaged girders with reduced plate thicknesses due to corrosion.","PeriodicalId":170570,"journal":{"name":"Second International Interactive Symposium on UHPC","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122298683","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
