Abstract In wind disasters, the closed structures will become open structures after being destroyed, and the internal pressure of the structures will suddenly increase, which has greater damages to the structures. At present, the researches on wind-induced internal pressure mainly focus on the structure with opening on windward wall, but ignore the situation of leeward wall with opening. Firstly, the calculation method of wind-induced response of structure with opening on leeward wall was deduced theoretically. Then the natural frequencies of the internal pressure system and the internal pressure responses obtained from the field measurement and the theoretical calculation method were compared to verify the accuracy of the theoretical method. After that, a rational method about the opening area on the leeward walls was explored and established, which was demonstrated to have obvious effects on improving the load conditions of roofs under strong wind.
