| Abstract | The bonding behavior of reinforcing bars embedded in Ultra-high Strength Concrete (UHSC) with steel fibers is discussed. Ten steel-fiber-reinforced UHSC specimens including three UHSC beams and seven lap-spliced UHSC beams were fabricated to investigate the bonding behavior. The compressive strengths of these specimens ranged from 130 to 150 MPa along with volume of steel fibers from 0 to 2%. The tensile behavior enhanced by different amounts of steel fibers was also compared using small-scale bending tests. In the UHSC beam tests, considerable bonding strength was identified in that the specimen with a lap-splice length of 10 d $_{ b }$ exhibited flexural responses equivalent to those from the specimen without lap splices. In addition, the ductile failure was ensured when a moderate amount of steel fibers was incorporated by compensating the brittleness of UHSC. These experimental results indicate that remarkably short splice length is applicable to the UHSC structure by incorporating sufficient amount of steel fibers. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
