Seismic Support Bracket

Seismic Support Bracket

1. Seismic bracing objectives: minor earthquakes cause no damage, moderate earthquakes can be repaired, and major earthquakes do not result in collapse.

2. Seismic bracing objective: Under the influence of frequent earthquakes with a magnitude lower than the local seismic fortification intensity, the main structure should remain undamaged and continue to be usable without repair.

3. Seismic bracing objective: Repairable after moderate earthquake, meaning that when affected by an earthquake equivalent to the local seismic fortification intensity, damage may occur, but the structure can still be used after general repairs.

4. Seismic bracing objective: To prevent collapse or severe damage that poses a threat to life during rare earthquakes with magnitudes exceeding the seismic fortification intensity of the local area.

5. Seismic fortification categories: Special fortification, Key fortification, Standard fortification, Moderate fortification.

6. Special Seismic Support Structures: Refers to buildings equipped with special facilities for use, involving major construction projects and potentially causing severe secondary disasters during earthquakes, which require special defense measures.

7. Seismic Bracing - Key Defense Category: Refers to buildings related to lifelines that cannot have their functions interrupted or need to be restored promptly during an earthquake, as well as buildings that may cause heavy disaster consequences such as significant loss of life during an earthquake, requiring an enhanced defense standard.

8. Seismic bracing standard defense category: Refers to buildings that are fortified according to standard requirements, excluding those with special, key, or moderate defenses.

9. Seismic Support Systems with Moderate Defense: Refers to buildings with sparse occupancy and where seismic damage will not lead to secondary disasters, allowing for moderate relaxation of requirements under certain conditions.
