The reverse shear force below the flexural plastic hinge (the hinge at the location above the podium level) may be much larger than the base shear above the flexural hinge, […]

With sufficient concrete cover, a multi-axial stress state develops in the concrete surrounding the reinforcing bar at both sides of the cracked interface. After increasing interface displacement, the concrete plasticizes […]
EK602
Mechanism condition: The ultimate or collapse load is reached when amechanism is formed. The number of plastic hinges developed should bejust sufficient to form a mechanism.
EK601
The cross section is not capable of resisting any additional moment but may maintain this moment for some amount of rotation in which case it acts like a plastic hinge.
EK586
Provided the section can also sustain the moment during the additional plastic hinge rotation till the failure mechanism is formed. Such sections are referred to as plastic sections.

The response of the beam remains linear and elastic almost to the stage when the stress in the extreme fibre has reached the value of the yield stress. From there […]

When steel bars or rods are placed across the joint, shear forces can be transferred between elements by dowel action. The dowel is loaded by shear at the joint interface […]
EK149
If the beam was statically indeterminate, the plastic hinge does not reduce it to a mechanism, and it can support any additional load. This additional load causes a redistribution of […]
EK148
If the beam was originally statically determinate, plastic hinge reduces it to a mechanism, and prevents it from supporting any additional load.
EK147
As the load on a ductile steel beam is increased, the stresses in the beam also increase, until the yield stress is reached. With further increases in the load, yielding […]
EK126
The yield zone is developed over a certain length, normally called the plastic hinge length, depending on the loading, boundary conditions, and geometry of the section. Plastic hinges are developed […]
EK124
A plastic hinge is said to form in a structural member when the cross-section is fully yielded.
EK80
Inelastic analyses can be generalized into two approaches. The first approach is known as plastic hinge analysis. The analysis assumes that structural elements remain elastic except at critical regions where […]
