Experimental Investigation of Utilizing Steel Fiber as Concrete Reinforcement in Bridge Decks

An Investigation on Transversely Prestressed Concrete Bridge Decks

This study is concerned with the development of design specifications for the use of transverse post-tensioning in concrete bridge decks. The ultimate goal behind this proposal is to improve the durability of concrete bridge superstructures. Experimental results from previous studies are used to validate the analytical models implemented in the development of the design specifications. It is fo...

Experimental Investigation of Behavior of Glass Fiber Reinforced Concrete (GFRC)

The paper presents the results of casting and testing of 264 GFRC specimens. The glass fibers were 25 mm long, with the aspect ratio (L/D) ranging between 1250 and 3570. The parameters studied were the ratio (by weight) of fibers to cement, i.e. F/C=0%, 1.5%, 3%, and 4.5%, and the ratio of coarse to fine aggregates (gravel to sand), i.e. G/S=1.1, 0.7 and 0.2. In total, 12 mix designs were selec...

Experimental Investigation of Multihazard Resistant Bridge Piers Having Concrete-Filled Steel Tube under Blast Loading

This paper presents the development and experimental validation of a multizard bridge pier concept, i.e., a bridge pier system capable of providing an adequate level of protection against collapse under seismic and blast loading but not acting simultaneously . A multicolumn pier-bent with concrete-filled steel tube CFST columns is the proposed concept, and the adequacy of this system is experim...
