What are the seismic design measures for steel houses?

Seismic design measures for steel-framed houses include the following aspects:

1. Selection of appropriate structural form: steel structure houses should select appropriate structural forms according to different heights and uses, such as frame structure, frame-supported structure, frame-core structure, and so on. Meanwhile, structural forms unfavorable to seismic resistance, such as single-span frames and irregular plane structures, should be avoided.

2. Strengthen the structural integrity and stiffness: by increasing the sectional size of members, adopting high-strength steel, setting supports and connectors, etc., the integrity and stiffness of the steel structure house can be improved, to enhance its ability to resist seismic effects.

3. Adopt seismic isolation and damping technology: Setting seismic isolation bearings or damping devices between the foundation and the main structure of the steel structure house can reduce the influence of seismic waves on the main structure, and lower the dynamic response and damage degree of the structure.

4. Optimize the design of nodes: nodes are the key parts of steel structure houses, and their design should fully consider the force and deformation performance under the action of an earthquake. Reasonable connection methods and strengthening measures should be adopted to ensure that the nodes will not be damaged or fail in the earthquake.

5. Improve the ductility performance of components: steel has good ductility performance, but in an earthquake may still occur brittle damage. Therefore, measures should be taken to improve the ductility performance of components, such as the use of reasonable cross-section form, control of the carbon content of steel, and low-temperature impact toughness test.

6. Strengthen the construction quality control: the construction process should strictly control the production and installation quality of components, to ensure that the connection of components and weld quality are in line with the specification requirements. At the same time, quality inspection and acceptance should be carried out to ensure that the construction quality of steel structure houses meets the design requirements.

It should be noted that the above measures are not isolated but should be considered and applied in an integrated manner to ensure the safety performance of steel structure houses in earthquakes. In addition, individualized design and construction should be carried out according to specific engineering conditions and needs to achieve the best anti-seismic effect.
