Computer Aided Seismic Analyses for Power Products Computer Aided Mechanical Engineering - conference in Cracow January 1, 2011. ) for static loads or dynamic loads , in case of linear or non-linear analysis ; You have knowledge of nuclear domain and safety. Two stages of analysis were conducted for finite element models, including elastic analysis and nonlinear analysis. There is a tool to convert acceleration in time function to spectrum, it is function of aceleration depending on vibration periods. Three values of the wall overstrength factor were selected in the dynamic analysis using ABAQUS: 1. Time history dynamic seismic analysis for the through-wall cracked piping was performed using ABAQUS. Our approach benefits clients by: Accelerating the process of analysis and modelling using our in-house templates. This section presents an application of the user-defined element developed earlier. Free Online Library: Analysis of cylindrical tunnels under combined primary near fault seismic excitations and subsequent reverse fault rupture. 92 ''Combining Modal Responses and Spatial Components in Seismic Response Analysis'' was last revised in 1976. ·Response spectrum analysis with seismic load E1 and E2 according to Chinese bridge seismic specifications ·Dynamic time-history analysis by using the design data from response spectrum analysis (E1&E2) according to random vibration theory ·”Pushover” method to acquire the maximal lateral displacement of the bridge. The use of finite element techniques is no longer limited to large companies and research laboratories.
