For concrete specimen subjected to uniaxial compression, the stress reaches the maximum when the strain reaches the ultimate compressive strain.
举一反三
- The common failure characteristic for the large and small eccentrically compressed reinforced concrete members is that the concrete in compression zone reaches the concrete ultimate compressive strain at the failure.
- When the soil reaches the limit equilibrium state, the location of shear failure surface must be on the maximum shear stress surface（ ）
- What is the ratio of vertical stress to vertical strain for soil under zero lateral strain condition? A: Constrained modulus of compression B: Deformation modulus C: Young’s modulus D: Coefficient of compression
- Under a certain long-term load, concrete would creep. In the reinforced concrete axial compressive members: A: Creep increases the compressive stress of concrete. B: The compressive stress of concrete and steel bar keeps unchanged. C: Creep decreases the compressive stress of concrete and increases the compressive stress of steel bar. D: Creep increases the compressive stress of concrete and decreases the compressive stress of steel bar.
- The cross section of a straight beam remains plane when the beam deforms due to bending. This causes ( ) on one side of the beam and ( ) on the other side. The neutral axis is subjected to ( ) .? normal stress; shear stress; zero stress|tensile stress; compressive stress; zero stress|compressive stress; tensile stress; maximum normal stress|shear stress; normal stress; zero stress
