Evaluating and upgrading concrete slab bridges is an important issue. A large part of the existing infrastructure has been built about 50 years ago and the design life has been reached or will be reached in the near future. Also traffic loads have increased significantly over the last 50 years...
In a previous study, the performance of UHPC slab under blast loads had been investigated through free air explosion tests. The blast resistance capacity of UHPC had been demonstrated through comparison with normal strength concrete. In the present study, the dynamic performance of UHPC slab under ...

The existing methods are rely on improving the Lagrangian or Eulerian methods to simulate projectile penetration into the reinforced concrete slab. The Lagrangian method is traditionally used to solve the penetration problem. Two solutions have been developed to avoid cell distortion in the large deforma...
PROBLEM TO BE SOLVED: To maintain proper accuracy, and prevent the occurrence of an overturn or the like at the time of a precast concrete slab erection work by applying the constitution that the lower side of a precast concrete slab and the floor of a story immediately below a story for ...
The prestressed and steel-reinforced concrete slab (PSRCS) is an innovative composite structural member offering high load capacity and stiffness and exceptional anti-crack performance, making it a leading trend in composite structures. This paper presen
Aiming to assess the actual slab-interaction effects on the overall response, a full 3D Finite Element (FE) model representative of a beam-to-column composite joint taking part of a braced frame is described in ABAQUS and validated towards past full-scale experiments. A parametric study is ...
Reuse Concrete Existing Structures Footbridge Arch Structural Design Life Cycle Assessment Circular Economy 1. Introduction 1.1. Context Concrete, currently the most ubiquitous construction material on earth, is made of sand and gravel bonded together by cement reacted with water. To produce the cement...
(I am not sure what the reason is, we do not have any existing calculations). The future opening would therefore cut through what seems to be the main bottom bars. Can anyone please provide consultation on what should be done to reinforce the slab, and confirm that the diagonal bars are...
