Member Forces

Internal member forces are returned for positions along each member based on the number of evaluation points specified in the request settings.

Result Key Type Description
member_forces Object Each key within this object corresponds to the member ID which holds an object of member forces.
Each key within the member object is the percentage along the member (i.e. 0-100%).

The member forces object is structured as shown in the table below.

Result Key Type Unit Description
axial_force Object Force Axial Force (in the member's local x-axis).
shear_force_y Object Force Shear Force in the member's local y-axis.
shear_force_z Object Force Shear Force in the member's local z-axis.
bending_moment_z Object Force-Length (Moment) Bending Moment in the member's local z-axis.
bending_moment_y Object Force-Length (Moment) Bending Moment in the member's local y-axis.
torsion Object Force-Length (Moment) Torsion in the member's local z-axis.
