In order to study the influence of openings of door, window and roof on the tsunami force on low-rise houses, physical model experiments were conducted under different wave heights of tsunami bores which were generated by dam-break method. The influence mechanisms and rules of the opening rate and opening position were investigated, based on which, the influence coefficients of the opening rate and position are proposed. Results show that an opening on walls makes the peak value of the horizontal tsunami force occur at the fluctuation stage. The occurrence time is delayed and the peak value of the horizontal tsunami force becomes smaller when the opening rate of the walls increases. Also when the opening is closer to the high-energy zone of tsunami bore, the horizontal tsunami force becomes smaller. The openings on the roof can release the entrapped air, thus reducing the pressure on the roof bottom and finally reducing the positive vertical force in the quasi-stable stage. However, the openings on the roof can increase the horizontal tsunami force on structure by 20%, which should receive attentions.
