   Author : Hamid Movaffaghi; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; finite element method; Earthquake excitation; global and local optimization; viscoelastic passive dampers; stochastic simulation; structural earthquake response analysis;

   Abstract : AbstractEarthquakes are one of the most dangerous natural phenomena causing damage to buildings and other structures as well as injury and death of people. These destructive processes can never be prevented to happen, but their impact on the structures can be minimized. READ MORE

4. 2. Analysis of underground concrete pipelines subjected to seismic high-frequency loads
