In order to improve the seismic performance of long-span double deck steel truss continuous girder bridge. taking Dao Qing Chau Bridge in Fuzhou as an engineering background. the isolation scheme of friction pendulum bearing (FPB) and friction pendulum bearing combined with viscous dampers is applied to study seismic performance. A three-dimensional dynamic model of the bridge is esta... https://unitedssports.shop/product-category/ball-glove-softball-catcher-senior/
