Investigation of punchout distress of continuously reinforced concrete pavement
… in terms of transverse and longitudinal bending stresses under load. One of the models, the ILLI-SLAB program, was found to be versatile and provide accurate results. Other comparisons were also made with the structural response models on the basis of crack width, steel stresses, and concrete …

Study of Internal Strains Developed in Concrete Decks at Early Ages in Steel Continuous Bridges
… identified bridge deck cracking shortly after concrete decks are placed and prior to applying traffic loads. Previous researchers have confirmed improper construction practices and design methods can lead to deck cracking. Currently, many contractors throughout Arkansas are using continuous …

Numerically Modeling Steel Continuous Bridges for Early Age Concrete Deck Cracking
… relatively short bridges, 180 to 190 ft. long. Concrete cracking occurs when concrete tensile stresses exceed the concrete’s tensile strength. Therefore, early age bridge deck cracking is evaluated in this thesis be monitoring induced concrete tensile stresses and comparing these values with the …

Early-age behavior of CRCP and its implications for long-term performance
Continuously Reinforced Concrete Pavement (CRCP) is the most widely used rigid pavement type in Texas. The advantages of CRCP over other rigid pavement types include the absence of transverse contraction joints. With the increased use of CRCP, a vast amount of information has been collected on …

Structural modelling and earthquake analysis of a hospital building located within the Tjörnes fracture zone in Iceland
… is not satisfactory for earthquake excitation. Concrete stresses are generally found to be low. The density ratio of walls compared to the floor area was calculated to be 7% total experiments have shown that this is a indicator of a good seismic performance.
