強震観測・強制振動実験・常時微動計測に基づく隣接する中低展延物の振動特性

抄録

In order to comprehend dynamic characteristics of adjacent 3-story RC building and 6-story Steel Reinforced Concrete (SRC) building, earthquake observation, forced vibration experiment and microtremor observation were carried out. The following results are obtained. The adjacent buildings are affected by both of Soil-Structure Interaction (SSI) and Dynamic Cross Interaction (DCI). The input loss of earthquake motion is not clear for both of adjacent buildings. The dynamic characteristics of smaller building are much affected by larger one. DCI effects are shown to be transmitted by soil, including rocking and torsion of buildings.
