Abstract: Modern structures must be designed for satisfactory serviceability over a long lifespan: 100 years or more. The camber or the deflection must not be excessive during the design lifespan. The present paper concerns the ...

Abstract: This paper analyzes bridge decks and two-way horizontal slabs with or without beams or drop panels using a grid analogy. The grid members are beams with a horizontal centroidal principal axis. The nodal displacements are ...

Abstract: ACI 318-05 considers that unbalanced moment,

Abstract: The paper presents an up-to-date procedure to design shear-resistant concrete flat plates of optimum thickness. Excessive long-term deflection is avoided by the reliable prediction of probable deflection while accounting ...
