Uniaxial compression and tension tests were used to determine the mechanical properties of HPFRCC materials. In order to investigate the effects of HPFRCC...

...Keke Peng; Banfu Yan In order to improve the performance of wet joints in prefabricated ultra-high-performance concrete (UHPC) bridges, a comparative study was conducted to investigate the flexural behaviour of UHPC joint beams. Experimental tests were implemented on a complete beam and on five...

...Xian Li; Yu Xiao; Tao Zhou; Yu-Ming Xu; Chun-Hui Li To facilitate construction and on-site quality testing, a new type of panel joint using cast-in-place connecting beams was developed and studied. The proposed connecting beams consist of overlapping vertical U-shaped steel bars stretching out...

Slip of the beam longitudinal reinforcement in the joint and shear deformation of the joint panel significantly decrease the rigidity of the joint and make a significant contribution to the lateral response of RC buildings...

... beams) are tested. Based on the experiments, the flexural strength of the segmental beams is found to be approximately 0·75 of that of the monolithic beam, and the joint types of CSWs are found to have a little effect on the load-bearing capacity of the segmental beams. Moreover, the load-bearing...
