Parameters:

Dmax (float) – Maximum displacement of the pushover.
Dincr (float) – Increment in the displacement.
IDctrlNode (int) – control node for the displacements.
IDctrlDOF (int) – DOF for the displacement.
elements (list) – beam and column elements in one single list to record rotations.
norm (list, optional) – List that includes the roof displacement and the building weight to normalize the pushover and display the roof drift vs V/W plot. The default is [-1,1].
Tol (float, optional) – Norm tolerance. The default is 1e-8.

Returns:

techo (float) – Numpy array with the roof displacement recorded during the Pushover..
V (float) – Numpy array with the base shear (when using an unitary patter) recorded during the Pushover. If pattern if not unitary it returns the multiplier.
PRot (float) – Numpy array with the rotation at the specified elements.

opseestools.analisis.pushover2T(Dmax, Dincr, IDctrlNode, IDctrlDOF, norm=[-1, 1], Tol=1e-08)

Dincr (float) – Increment in the displacement.
IDctrlNode (int) – control node for the displacements.
IDctrlDOF (int) – DOF for the displacement.
norm (list, optional) – List that includes the roof displacement and the building weight to normalize the pushover and display the roof drift vs V/W plot. The default is [-1,1].
Tol (float, optional) – Norm tolerance. The default is 1e-8.

Returns:

techo (numpy array) – Numpy array with the roof displacement recorded during the Pushover.
V (numpy array) – Numpy array with the base shear (when using an unitary pattern) recorded during the Pushover. If pattern is not unitary it returns the multiplier

Function to calculate the pushover

Parameters:

Dmax (float) – Maximum displacement of the pushover.
Dincr (float) – Increment in the displacement.
IDctrlNode (int) – control node for the displacements.
IDctrlDOF (int) – DOF for the displacement.
elements (list) – elements to record forces and stresses.
norm (list, optional) – List that includes the roof displacement and the building weight to normalize the pushover and display the roof drift vs V/W plot. The default is [-1,1].
Tol (float, optional) – Norm tolerance. The default is 1e-8.

Returns:

techo (numpy array) – Numpy array with the roof displacement recorded during the Pushover.
V (numpy array) – Numpy array with the base shear (when using an unitary pattern) recorded during the Pushover. If pattern is not unitary it returns the multiplier
T (numpy array) – Numpy array with the building period recorded during the Pushover.
Eds – Numpy array with the forces in the elements (columns and beams). The order is determined by the order used in the input variable elements. The array has three dimensions. The first one is the element, the second one the pushover instant and the third one is the DOF.
Strains – Strain at the macrofibers of the wall. Records eight.
cStress – Concrete stress at the macrofibers of the wall. Records eight.
sStress – Steel stress at the macrofibers of the wall. Records eight.
