Building anti-seismic risk detection method

The embodiment of the invention discloses a building anti-seismic risk detection method, and the method comprises the steps: obtaining a first shear force borne by a reference position when a whole building is in a vibration risk environment shown by an anti-seismic standard parameter according to a building design parameter and the anti-seismic standard parameter; obtaining a second shear force applied to the reference position when the single limb is in a vibration risk environment shown by the anti-seismic standard parameters, wherein the reference position is the position, located on the same floor as the designated position, of the single limb; the designated position is a connection position between the single bodies of the building. According to the difference value between the first shearing force and the second shearing force and the relative position relation between the reference position and the designated position, the bending moment caused by the single limb to the designated position is determi
