Accepting the challenge of the future in the field of civil engineering smart structure applications, the province of Manitoba is undertaking the responsibility of constructing the first bridge in Canada totally prestressed and reinforced for shear by cru:bon fibre reinforced plastic (CFRP) reinforcement. Portion of the concrete deck slab is also reinforced exclusively by FRP reinforcements. Th...

Continuous tunneling using a tunnel-boring machine is very popular method when it comes to the construction of large tunnel projects. The use precast reinforced concrete elements, called tubbings, highly economical way secure post excavation. Unfortunately, loss load-bearing capacity has been observed in past joints between tubbings. Reasons for that are among others required reduction cross se...

Abstract A bulk volume of waste tires, an underrated global resource, is disposed in landfills worldwide. Extracting recycled steel fibers from these tires evolving trend nowadays. The outcomes concrete having sourced end-of-life are alike industrial fibers. Accordingly, the attention researchers focused nowadays on using alternative place concrete. In current study, review focuses recycle tire...

This study deals with the numerical modeling of symmetrical water entry of tunneled sections. In this study, firstly, the water entry problem of a wedge section without tunnel in four different deadrise angles was numerically modeled. The obtained results related to the pressure distribution on these sections and the maximum pressure have been compared with the experiment results. In the next s...
