In the current frame structure desi

In the current frame structure design, the horizontal design usually ignores the vertical frame design. The current building anti-seismic design code requires that the horizontal seismic action should be calculated separately in the two main axis directions, and all aspects of the seismic action should be borne by the lateral force-resistant members in this direction. In the frame structure design, the vertical frame and the horizontal frame have the same importance. Some structures require designers to take non-seismic considerations, and the longitudinal design is based on ordinary continuous beams. The configuration of the beam-column nodes and the longitudinal reinforcement and stirrups in the frame cannot meet the structural requirements of the frame. Because the longitudinal effects of earthquakes are not considered, in the actual design, there are often insufficient reinforcements of the beam supports, the longitudinal reinforcements and the stirrups in the mid-span.
