The stronger the foundation is, the stronger the earthquake resistance is, the anti earthquake is said
Building materials for a house. Whether the concrete mark is enough or not, whether the steel bar is qualified or not, is it important to cut corners and so on.
Construction quality of the house. Map construction, technology in place, the quality of housing is good. Otherwise, better design, poor construction quality will also be a problem.
The structure of a house. The seismic capacity of brick concrete structure is weaker than that of reinforced concrete frame and frame shear wall. The bottom frame of the upper brick, with the transfer layer of the house, the bottom of the open house, column column system houses, seismic capacity is relatively poor. The bottom layer is weak and easy to sit down.
The shape of a house. Regular, uniform and symmetrical houses have strong seismic resistance. The big head heavy housing shape called vertical irregular plane, local convex L shaped, T-shaped shape is irregular plane, a head of a heavy head light is called irregular torsion, irregular buildings have poor seismic capacity.
