This study offers numerical simulation results using the ABAQUS/CAE version 2019 finite element computer application to examine performance, and residual strength of eight recycle aggregate RC one-way slabs. Six strengthened by NSM CFRP plates were presented impact several parameters on their structural behavior. The experimental four selected slabs under monotonic load, plus one slab repeated ...

In this paper the parametric study is carried out to investigate the effect of number of cells in optimal cost of the non-prismatic reinforced concrete (RC) box girder bridges. The variables are geometry of cross section, tapered length, concrete strength and reinforcement of the box girders and slabs that are obtained using ECBO metaheuristic algorithm. The design is based on AASHTO standard s...

Reinforced concrete (RC) submerged floating tunnels (SFTs) represent a possible solution for crossing wide, deep fjords, and is considered the E39 highway route along Norwegian west coast. With regard to SFTs, specific accidental scenario that under investigation combined action of fire subsequent internal explosion, as this crucial safety design condition type structure. To assess structural p...

This paper describes a method of performance evaluation and remaining life prediction for an aged reinforced concrete (RC) T-girder bridge by J-BMS RC version via close visual inspection data, and also verifies the assessment results obtained as outputs from the Bridge Rating Expert System (RC-BREX) which is a subsystem of the J-BMS, to evaluate the effectiveness of the system. The Bridge Manag...

Abstract Flexural shear behavior, which mainly concerns reinforced concrete (RC) slabs without reinforcement, is usually investigated by means of simply supported, beam‐shaped specimens. Only few tests are available where the cross‐section properties correspond to a slab ( b ≫ h ) or support conditions lead moment and force distributions multi‐span systems. The distribution in vicinity inner su...
