Description
Technical Field
The invention relates to the technical field of building structures, in particular to a reinforced concrete mixed shear wall with replaceable earthquake damage parts.
Background
The earthquake-proof idea at the present stage of China is that 'small earthquake is not damaged, medium earthquake can be repaired, and large earthquake is not fallen'. This seismic concept requires that the major structure should not be significantly damaged and repaired after the structure encounters a seismic event with a fortification intensity. However, due to the uncertainty and complexity of seismic action, the structure may be subjected to seismic action greater than the intensity of the fortification, which can severely damage the structural members. In addition, although the structure may not collapse after suffering from an earthquake with fortification intensity, part of components cannot be repaired due to overlarge residual deformation, and finally, the whole structure can only be overturned and rebuilt, so that huge waste is caused, and the normal life of people is also influenced. Therefore, a recoverable functional structure is designed, so that the structure can recover the normal use function of the structure after an earthquake as soon as possible. Therefore, the building can not only protect the life and property safety of people in an earthquake, but also help people to recover normal life as soon as possible after the earthquake. Therefore, it is still necessary and meaningful to develop a reinforced concrete hybrid shear wall form capable of reducing residual deformation and replacing the damaged parts with the conventional reinforced concrete shear wall with poor repairability.
