A project is an octave earthquake resistant, and the bottom of the balcony side beam is reinforced i

The anchorage length is directly related to the seismic grade of frame beams, columns and shear walls, but not directly related to the fortification intensity.

Seismic anchorage is a seismic structural measure, which is not a frame beam and plate, and there is no seismic structural measure.

Therefore, the bottom reinforcement of the covering beam of the balcony is anchored into the lifting beam for 12d, and the negative reinforcement is bent downward for 15d to the opposite side of the lifting beam.

Anchoring means that the reinforcement is wrapped in concrete, which strengthens the connection between the concrete and the reinforcement and makes the building stronger, with the aim of enabling the two to work together to bear various stresses (working together to withstand pressure, tension, bending moment, torque, etc. from various loads). The position and form of anchoring, can be used hook, bending and other forms, can also refer to the length of the reinforcement anchored into the component, if there is not enough anchorage length, the reinforcement force can not be effectively transmitted to the anchor solid, in order to ensure the effect of reinforcement force transmission, the specification stipulates that the anchorage length is not less than 200mm.

The inscription 'Octave Earthquake Resistance' is the fortification intensity, not the seismic rating.

The anchorage length is directly related to the seismic grade of frame beams, columns and shear walls, but not directly related to the fortification intensity.
