Abstract: Based on the limited information on the tensile stress–strain relationship of ultra-high-performance concrete (UHPC) with treated fibers, the objective of the present research is to experimentally investigate the flexural ...

Abstract: Ultrahigh-performance concrete (UHPC) is a type of concrete that has gained attention from researchers for its potential use in various structural applications to improve the behavior of concrete structures. Despite this ...

Abstract: Ultra-high-performance fiber reinforced concrete (UHPFRC) exhibits strain hardening and multiple cracking behaviors when subjected to tension load. There are limited studies on the effect of steel fiber aspect ratios on ...

Abstract: Recent research on ultrahigh-performance concrete (UHPC) for connection elements in highway bridges indicates an improvement in the performance of the overall bridge superstructure. However, there is limited information ...

Abstract: Adjacent box-girder bridges have become a popular choice as they can be constructed quickly, easily, and economically. In spite of their good performance during many years of service, one major problem has been recurrent ...

Abstract: Precast adjacent box girder bridges have become a preferred solution in several states due to their simple structure, economy, and ease of construction. However, longitudinal cracks often appear along the shear keys between ...

Abstract: This research aims to experimentally investigate the flexural behavior of ultra-high-performance concrete (UHPC)–steel composite beams with joints under a negative bending moment in order for the results to be used in the ...
