The application of carbon-,ber-reinforced polymer (CFRP)sheets for strengthening deteriorated concrete structures is be-coming widely accepted around the world ,Bakis et al. 2002;Teng et al. 2003,.The system uses high-strength, light-weight,and corrosion-resistant materials.Bene,ts of this type...
Prestressed concrete bridge girders (PCBG) are susceptible to damage when exposed to overheight vehicle collisions. This paper presents high-fidelity finite element models developed using LS-DYNA software. Thirteen models were validated against experimental data from the literature. The validated models ...
Steel strands for use in prestressed concrete structures, also known as PC-strand Hjulsbro Steel’s PC-strand product range consist of 3- and 7- wire strands made from high-quality wire rod in various steel grades depending on application. The detailed specifications of each PC –strand, such...
