Slabs punching shear capacity for normal strength concrete (NSC) and high has been investigated in this paper. Due to the significance of technology construction industry, more attention paid Then, detailed comparison is carried evaluate outcome by referring several existing standards. tests have collected from reported results literature. Forty-seven tested slab specimens grouped available pub...

In this paper, a novel sonoelastographic technique for estimating local shear velocities from propagating shear wave interference patterns (termed crawling waves) is introduced. A relationship between the local crawling wave spatial phase derivatives and local shear wave velocity is derived with phase derivatives estimated using an autocorrelation technique. Results from homogeneous phantoms de...

Seismic analyses of concrete structures under maximum-considered earthquakes require the use of reduced stiffness accounting for cracks and degraded materials. Structural walls, different to other flexural dominated components, are sensitive to both shear and flexural stiffness degradations. Adoption of the gross shear stiffness for walls in seismic analysis prevails particularly for the design...
