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.
EK599
Plastic analysis is based on the idealization of the stress-strain curve aselastic-perfectly-plastic. It is further assumed that the width-thickness ratio of plate elements is small so that local buckling does […]
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.
EK396
The deflection and rotation of the beam due to its loading will cause a concentration of bearing at the front edge and, depending upon the load from above the bearing, […]
EK314
For limit design to be valid, four conditions must be satisfied: Mechanism condition: Sufficient plastic hinges must be formed to transform the whole or part of the structure into a […]
EK172
A joint may be classified as nominally pinned if its design moment resistance is not greater than 0,25 times that required for a full strength joint, provided it has sufficient […]
EK152
The simple joint should therefore have sufficient rotation capacity to permit member end rotations to occur without causing failure of the joint or its elements.
