举一反三

The main failure modes of inclined section of flexural members can be ordered as ( ) from high to low according to the corresponding shear capacity. A: inclined tension failure > shear-compression failure> inclined compression failure B: shear-compression failure > inclined tension failure > inclined compression failure C: inclined compression failure > shear-compression failure> inclined tension failure D: shear-compression failure> inclined compression failure > inclined tension failure
The failure modes of foundation include general shear failure, local shear failure and punching shear failure（）
The main difference of the failure characteristics between the large and small eccentrically compressed reinforced concrete members is whether the reinforcement on the far-side from the axial force is in tension or compression at the failure.
The most effective measure to avoid the inclined compression failure for a beam is by ( ). A: increasing the amount of stirrups B: increasing the section size C: increasing the amount of web reinforcements D: increasing the amount of bent-up reinforcements
Progmatic failure can be categorized as pragmalinguistic failure and sociopragmatic failure.

If [img=46x23]1803b95368d5b28.png[/img], the concrete fiber strain at the edge of the compression zone at the failure of the beam satisfies the condition [img=59x19]1803b95371d436c.png[/img], and at the same time, the tensile strain of the tensile reinforcements satisfies the condition [img=53x22]1803b95379d4907.png[/img], i.e., the tensile reinforcement has yielded at the failure of the beam, and the failure mode of such beam belongs to the over-reinforced failure.

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.
3
In Mohr-Coulomb failure criterion, failure occurs when the ______ is achieved and not when the maximum shear stress is achieved.
