Structural Behavior of Normal and High Strength Concrete ...

The deflections of concrete wall panels depend on the slenderness ratio (H/t), aspect ratio (H/L) and concrete strength. The failure mode of the concrete wall panels is greatly affected by the aspect ratio (H/L); the panels with low aspect ratio tend to fail by crushing, while panels with high aspect ratio tends to fail by buckling. concrete ...

Lateral strength and ductility of reinforced concrete ...

May 03, 2019 · In general, the compressive strength of concrete has an inverse relationship with its ultimate strain, meaning that high-strength concretes are less ductile than those of lower strength. As shown in Fig. 14 b, the increased compressive strength of the concrete led to a significant reduction in the ductility of the column.

Compressive Strength Properties Perpendicular to the Grain ...

of the compressive strength perpendicular to the grain of CLT must be performed because timber- and wood-based materials generally have a lower measure of compressive strength perpendicular to the grain. Serrano and Enquist (2010) calculated the compressive strength perpendicular to the grains of three-layer CLT (spruce) compression test specimens.
