ANALYSIS OF DAMAGE TO AN SRC APARTMENT BUILDING DUE TO THE FUKUOKA PREFECTURE WEST OFFING EARTHQUAKE
The non-structural walls of a 14 story apartment building of steel reinforced concrete suffered severe damage due to the 2005 Fukuoka Prefecture west offing earthquake. The cause of damage is clarified by the damage investigation results and a comparison with the analysis of response results of this building. We found that the level of damage to the non-structural walls can be evaluated with good accuracy from response analysis of a rigidity zone model and 3-way slit model, considering the seismic wave amplification from the subsurface ground. Also, deformation is particularly great in steel reinforced concrete structures, and a width of approximately 1/100 of the wall height is insufficient for the slit width in the case of using 3-way splits in non-structural walls, and approximately 1/50 is necessary. Furthermore, innovations to improve the deformation performance of non-structural walls are necessary.
