Corrugated steel plate energy dissipation device
The invention discloses a corrugated steel plate energy dissipation device. The corrugated steel plate energy dissipation device comprises two energy dissipation columns, a corrugated steel plate and channel steel. The two energy dissipation columns are arranged in parallel. The channel steel and the corrugated steel plate are both installed between the two energy dissipation columns. The corrugated steel plate is installed between the two pieces of channel steel which are arranged up and down. The two ends of each energy dissipation column are each connected with a support with rotating friction. The two ends of each energy dissipation column are connected with the supports with rotating friction, on one hand, the contact faces of the energy dissipation columns and the supports are increased, stress concentration is effectively avoided, and the lateral rigidity of the energy dissipation device is improved; and on the other hand, when a component generates small back-and-forth lateral displacement, the ends of the energy dissipation columns rotate, rotating friction energy dissipation is conducted, the energy dissipation device can conduct energy dissipation under small displacement, the energy dissipation device and the corrugated steel plate conduct energy dissipation cooperatively when the component generates large displacement, and the energy dissipation efficiency is improved. Additional damping is provided for a main body structure.
本发明公布了波纹钢板消能器，包括有消能柱、波纹钢板和槽钢，所述消能柱为两根，两根消能柱平行设置，所述槽钢和所述波纹钢板均安装在两根消能柱之间，所述波纹钢板安装在上下设置的两个槽钢之间，所述消能柱的两端各连接一个带有转动摩擦的支座。消能柱的两端连接有带有转动摩擦的支座，一方面，增加了消能柱与支座连接的接触面，有效避免应力集中，并提高消能器的侧向刚度；另一方面，在构件产生较小往返侧向位移时，消能柱端部产生转动，进行转动摩擦耗能，使得消能器在小位移下即可进入耗能，在构件产生较大位移时与波纹钢板协同耗能，提高耗能效率。为主体结构提供附加阻尼。
