Event Time

Times at which yielding takes place in the members defined with inelastic hinges are produced in a table.

Table Tool in MIDAS/Gen offers a variety of powerful built-in functions. Refer to Usage of Table Tool for detail directions:

From the Main Menu select Results > Result Tables > Inelastic Hinges > Event Time

Upon executing the Event Time function, Records Activation Dialog prompts. Click after selecting nodes and elements, load cases, eigenmodes, etc. for which the results are to be produced.

Note

Refer to Results Table of "Usage of Table Tool" for the usage of Records Activation Dialog.

Refer to Usage of Table Tool and check the following data:

Event Time Tables

Elem: Element Number

Hinge Location: Locations where inelastic hinges are assigned. For Lumped Type, it displays as i, j, i & j, FX. For Distributed Type, it displays according to the number of hinges.

Load: Time History Load

DOF: Degree of freedom

1st Yield

Dx: Time at which the Dx component reaches the state of cracking

Dy: Time at which the Dy component reaches the state of cracking

Dz: Time at which the Dz component reaches the state of cracking

Rx: Time at which the Rx component reaches the state of cracking

Ry: Time at which the Ry component reaches the state of cracking

Rz: Time at which the Rz component reaches the state of cracking

2nd Yield

Dx: Time at which the Dx component reaches the state of yielding

Dy: Time at which the Dy component reaches the state of yielding

Dz: Time at which the Dz component reaches the state of yielding

Rx: Time at which the Rx component reaches the state of yielding

Ry: Time at which the Ry component reaches the state of yielding

Rz: Time at which the Rz component reaches the state of yielding

3rd Yield

Dx: Time at which the Dx component reaches the ultimate state

Dy: Time at which the Dy component reaches the ultimate state

Dz: Time at which the Dz component reaches the ultimate state

Rx: Time at which the Rx component reaches the ultimate state

Ry: Time at which the Ry component reaches the ultimate state

Rz: Time at which the Rz component reaches the ultimate state

Note

It produces the time at which the third yielding is reached in Tetralinear.

Note

If the time is indicated as “0”, it means that the state of yielding was never reached. In case of base isolator devices, Event Time is always indicated as “0” regardless of the state of yielding, due to the characteristics of the elements.
