Details of longitudinal rebars in characteristic areas of the beam

The longitudinal rebars are placed in order to resist the flexural tensile stresses that appear along the beam axis while stirrups are used to carry the diagonal tensile stresses caused by shear. Moreover, stirrups help in the critical areas confinement.
The number placed in front of the beam b1 indicates the floor that this beam belongs to. In this case, it is the number 0 which corresponds to the ground floor.

Frame node behaviour under seismic ground motion

A seismic ground motion causes reverse bending moments to the beam.


Fully anchored reinforcement in the joint area

In the joint area of an earthquake resistant frame both the upper and the lower reinforcement are fully anchored.
