As a rule, the experimental research was done at small format reinforced concrete slabs with span widths of 1.60m and slab thicknesses of 0.10m strengthened with TRC. At the same time calculation models were developed to predict the maximum bending load capacity of the reinforced components ...
The method predicts the flexural capacity and crack growth of large-scale concrete slabs with different geometries and materials by inserting cohesive surface elements on the expected crack path in the 3-D finite element model that represents the slab. The cohesive elements were defined by the ...
The behavior of two reduced-scale concrete bridge decks subjected to simulated wheel loads was evaluated in a series of tests. One slab was reinforced in accordance with AASHTO requirements; the other had three areas with varying amounts of isotropic reinforcement. Results show that with either rei...
This paper proposes a novel simplified analytical approach, named the slab strip model, to assess the ultimate bearing capacity of reinforced concrete (RC)... Matteo Colombo,Paolo Martinelli,Marco di Prisco - 《Structural Engineering International》 被引量: 0发表: 2020年 New analytical method for ...

In order to research the load-bearing capacity of pre-stressed concrete hollow slab in single slab load bearing state,the load-bearing capacity of existing hollow slab bridge is evaluated based on the test data of the pre-stressed concrete hollow slabs which have been used for 10 a.The resist...
This paper presents a literature survey of roof and floor slab systems constructed of assembled concrete blocks as manufactured in the 1940s, 1950s, and 1960s with a retrospective on load capacity considerations and serviceability. Assembled concrete blocks were formed by assembling a row of lightwe...
Hello all,I am trying to verify the load carrying capacity of a concrete beam reinforced with only longitudinal reinforcement at the bottom. For the analysis, I used nonlinear concrete (which has Drucker-Prager strength parameters defined) and nonlinear
SummaryThe lateral stiffness and strength required of supporting beams and exterior panels of continuous reinforced concrete slab-and-beam floors in order to ensure membrane action in the panels at ultimate load is considered. It is shown that tie reinforcement may be required in the supporting beams...
The joint of prefabricated concrete pavement slab is an important structural part of the prefabricated pavement slab. The joint damage will reduce the pavement function and accelerate the plate damage. The joint treatment technology is also a problem that puzzles engineering researchers. How to ensure...
