Based on GB50010-2010, ACI318-08, and CSA-04, three different shear models were established, and the calculated values of shear capacity are quite different, and the analysis of the shear strength of RC in the strengthened seismic-damaged SRC column …
WebbBecause of the lack of reliable and realistic theoretical or empirical relations and the difficulties in obtaining and testing representative samples, engineers rely on judgment and often consider the shear strength of the infilled material itself as … WebbThe theoretical shear strength was evaluated by Frenkel (1926). [19] where ds is the atomic distance along the slipping direction, dm is the distance between the row of atoms, and G is the shear modulus. As for the (111) plane of silicon, the theoretical shear strength becomes 13.7 GPa.
The theoretical yield strength of a perfect crystal is much higher than the observed stress at the initiation of plastic flow. That experimentally measured yield strength is significantly lower than the expected theoretical value can be explained by the presence of dislocations and defects in the materials. Indeed, whiskers with perfect single crystal structure and defect-free surfaces have been shown to dem…
