Wooden House

Thousands of wooden houses were destroyed by the 2016 Kumamoto Earthquake. A seismic damage prediction function for wooden houses taking into consideration the consecutive strong earthquake motions, the amplification effect of ground surface layer, and the rupture propagation effect of seismic fault was proposed in this paper. Relationship between three ground characteristics above mentioned and the seismic damage for wooden house in the 2016 Kumamoto earthquake was analytically investigated by 3-D collapsing process analysis. The maximum drift angle was evaluated in this collapsing analysis of two-story wooden house.

Wooden House

In general, the evaluation of a site amplification effect is very important in earthquake engineering when a seismic damage to wooden house with a low seismic performance against a strong earthquake will be predicted by an accurate estimation of the seismic intensity at surface ground. In this paper, both horizontal and vertical microtremors at 51 measuring sites in the west district in Maizuru city were measured by servo type accelerometers, and also the predominant periods at 727 sites in the same area were numerically estimated from the predominant periods measured at 51 sites using the Inverse Distance Weighting method. Moreover, a seismic damage prediction of wooden house against a strong earthquake ground motion was conducted by a relationship between a seismic damage function and a maximum drift angle of wooden house.
