Study on Earthquake Response Characteristics and Effects of Orthogonal Walls of Japanese Traditional Wooden Aparttment Called Nagaya

Abstract eng:
This paper presents the fundamental earthquake response characteristics of two-dimensional wooden-framed house models, Nagaya, with the uni-axial eccentricity. Differences of earthquake responses between the oneand four-unit Nagaya models are shown. The effect of wall quantity variation of the orthogonal direction on the vibration control is examined. It is found from the analytical results that the displacement responses of the one-unit model are larger than those of the four-unit one; therefore scrapping Nagaya consisted of several houses leads to the bad amenity during earthquake. When setting the orthogonal wall quantity of the models to one and half times as much as eccentric directional wall quantity, torsional vibration would be rarely caused. wooden-framed Nagaya, eccentricity, torsional vibration, effect of orthogonal wall
