Efficient Nonlinear Time History Analysis of California Bridges
| 项目名称： | Efficient Nonlinear Time History Analysis of California Bridges |
| 摘要： | Pacific Earthquake Engineering Research Center (PEER) report 2008/03 described modeling guidelines specific to both SAP2000 and Open System for Earthquake Engineering Simulation (OpenSees), with a comparison of the differences between the observed bridge responses. The report provided analysis guidelines and suggestions for optimal selection. Recently completed work by researchers at University of California, San Diego (UCSD) led to the development of a graphical user interface (GUI) for a set of OpenSees-based tools, named MSBridge. The GUI allows rapid model building for a broad range of typical bridge configurations, and graphically displays output. However, the work did not interpret results obtained via MSBridge, e.g., through parametric studies that could be used as a tool for establishing reasonable bounds on bridge response to seismic loading. This made it difficult to move forward with implementing nonlinear time-history analysis of ordinary California bridges. |
