実物超高減衰ゴム支承の曲げせん断変形に起因した取付ボルトの引張挙動

抄録

This research aims to understand the tensile force acting on the fixing bolts caused by the bending-shear deformation of an actual super-high damping rubber bearing. Loading tests were conducted on a developed loading system that allows bending-shear deformation of an actual rubber bearing for simulating tensile behavior of the fixing bolts. The tests achieved the bending-shear deformation on an actual rubber bearing. The tensile force acting on the fixing bolts increased nonlinearly from the bolts on the loading side caused by the tensile force generated at the rubber end. The maximum value was reached at the end bolt farthest from the loading side. In addition, numerical analyses were performed to grasp the effect of tensile force generated at the rubber end on the tensile behavior of the fixing bolts.
