Substantial cost savings can often be achieved on large bridge construction projects by using advanced structural analysis techniques. There are generally three methods of analysis used to determine the seismic response of bridges:
- Equivalent static analysis—an approximate linear elastic static analysis method most often used on simple bridges,
- Linear dynamic analysis—response spectrum analysis and/or linear elastic time history analysis both of which can often misrepresent the seismic response of a bridge,
- Nonlinear analysis using performance-based design—a more advanced approach that includes static pushover analysis and/or nonlinear time history analysis both of which produce a more accurate structural response of a bridge.
Over the past fifteen years, SC Solutions has successfully incorporated advanced nonlinear analysis using performance-based design procedures into a highly reliable, production environment. This has resulted in significant construction cost savings for many of today’s high profile bridge projects.
