The effects of fiber reinforced on resisting the upward movement of flexural cracking and increasing the concrete tensile strength are incorporated to the design equation. The fitting factors to match the predictions to experimental data are not employed by the approach. A depth correction is, however, used to account for the size effects. The proposed design equation is applied to predict the ultimate punching shear strength of 62 slab column connections tested involving a wide range of fiber variables, concrete type and strength, tension steel ratio, size of slab and loaded area. The paper presents the comparisons between computed values and the experimentally observed values.","PeriodicalId":400110,"journal":{"name":"SP-216: Innovations in Fiber-Reinforced Concrete for Value","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2003-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115068923","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}

The goal was to determine if this otherwise very brittle seismic response of HS-LWA concrete columns could be changed to a more desirable behavior, comparable to that of seismically designed normal weight concrete columns. Obtained data show a seismic response comparable to that of seismically designed columns made using conventional concrete filled tube or reinforced concrete members. Specimen response was stable until failure of the steel tube.","PeriodicalId":400110,"journal":{"name":"SP-216: Innovations in Fiber-Reinforced Concrete for Value","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2003-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123583946","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}

Investigated in this study is the effect of dispersion of fibers on the multiple cracking behavior of fiber reinforced composites. To record the location of crack initiation, sequence of multiple cracking and corresponding cracking stresses, the study used electronic speckle pattern interfometry technique. Microstructural parameters are statistically quantified by the theory of point processes at each crack location. The study calculated the size of the fiber free areas and fiber clumping at the crack cross sections. Also calculated was the fracture toughness of the matrix by using linear elastic fracture mechanics. The study results indicate that the toughness of the composite depends on the fiber clumping at the first crack cross section.","PeriodicalId":400110,"journal":{"name":"SP-216: Innovations in Fiber-Reinforced Concrete for Value","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2003-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124693847","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}

Contoured double-cantilevered beam specimens were subjected to one rate of quasi-static loading and three rates of impact loading by using a fully instrumented drop weight impact machine.

The comparison between steel and polypropylene fibers indicated a superior performance of the steel fiber under quasi-static loading, but under impact loading, the polypropylene fiber appears to come up to the level of steel fiber.","PeriodicalId":400110,"journal":{"name":"SP-216: Innovations in Fiber-Reinforced Concrete for Value","volume":"118 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2003-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123221605","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}

Lange","doi":"10.14359/12897","DOIUrl":"https://doi.org/10.14359/12897","url":null,"abstract":"The study reveals that additional steel fibers with a volume fraction of 0.50% influences the individual components of tensile creep in different manners. Steel fibers reduce the initial rate of tensile basic creep, but increase long term basic creep capacity. That suggests that fibers provide more stress relaxation in time. The study attributes this to the ability of the fibers to control microcracking, distribute internal stresses more uniformly and engage greater volume of the matrix in stress transfer. To avoid confusion in interpreting the stress relaxation of FRC from total tensile creep and drying creep test results, the study suggests dividing the stress relaxation mechanisms into beneficial and detrimental components. This study demonstrates an approach for testing tensile creep of concrete in order to isolate the mechanisms responsible for basic and drying creep.","PeriodicalId":400110,"journal":{"name":"SP-216: Innovations in Fiber-Reinforced Concrete for Value","volume":"254 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2003-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124181215","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}

The Imam calculates the contribution of the stirrups in the same way as the RILEM.
