The invention discloses a building structure instant internal pressure measuring device considering wind induced interference, and is applied to the field of wind tunnel test devices. The device comprises a test bench fixed in a wind tunnel and a building model arranged on the test bench. According to the building structure instant internal pressure measuring device considering the wind-induced interference, conditions that doors, windows and glass curtain walls and the like of a building are destroyed suddenly can be automatically controlled and simulated, effects of manual operation on testresults are reduced; meanwhile, positions and sizes of crevasses can be controlled autonomously, simulation of a multi-building structure arrangement in one set of test device can be realized, wind-induced interference factors in the building group are taken into account; meanwhile, relative positions of all the building structures, that is, distances between the buildings and the included anglesrelative to wind directions can be conveniently adjusted; research of influence of azimuths and positions of different buildings on a wind field can be carried out in a set of test devices to providesupport for theoretical studies provided in the field of instant internal pressure measurements.
