Reverse Engineering of existing reinforced concrete slab bridges

Most bridges in the Western European road networks are ageing. The vast majority of about 90% of these bridges have reinforced concrete as a building material. The traffic intensity, as well as the axle, and the average vehicle weight have increased since these structures were opened to traffic. Furthermore, the structural (design) codes have...

Validation of Nonlinear Finite Element Analysis on Reinforced Concrete Slab under Concentrated Out-of-plane Load Combined with Uniaxial In-plane Load Based on Case Study

Finite element analysis is becoming a popular tool for engineers recently. Nonlinear finite element analysis is more advanced due to that it can deal with the nonlinearity of structures, which leads to more accurate approximation of structural behaviour. In Model Code 2010, nonlinear finite element analysis, which belongs to the higher level of...

Plastic model for asymmetrically loaded reinforced concrete slabs

Most methods for the design and analysis of reinforced concrete slabs for punching are based on experiments on slab-column connections, reflecting the situation in building slabs. Slab-column connections with unbalanced<br/>moments have also been studied in the past. Experiments indicate that the accuracy of models for asymmetrically loaded...

Beam Experiments on Acceptance Criteria for Bridge Load Tests

Loading protocols and acceptance criteria are available in the literature for load tests on buildings. For bridges, proof load tests are interesting when crucial information about the structure is missing, or when the uncertainties about the structural response are large. The acceptance criteria can then be applied to evaluate if further loading...

Nonlinear finite element analysis of reinforced concrete slabs: Comparison of safety formats

According to the new fib Model Code 2010 the design shear resistance of a reinforced concrete (RC) structure can be evaluated through analytical and numerical calculation methods that fall into four different levels of approximations; the complexity and the accuracy of the calculated shear resistance increases with increasing the level of...
