| Outline of Final Research Achievements |
Ventilated exterior wall systems are commonly used for low-rise buildings. Because the net wind force on the external wall is the difference between external pressure and vent-layer pressure, the load may be reduced due to the effect of pressure equalization. On the other hand, the vent-layer pressure acts on the internal walls such as drywalls, which is not considered in the conventional design of walls. The present investigation discusses this subject based on a wind tunnel experiment of the external pressures on a low-rise building as well as on a numerical simulation of the vent-layer pressure. Based on both of the experimental and analytical results, wind force on each member is evaluated and a design guide is proposed for the ventilated exterior wall systems.
