A LMM-based seismic fragility analysis method for bridges
نویسندگان
چکیده
The common seismic fragility analysis methods are mainly inaccurate due to assumptions made in derivation process or time consuming because of large sample analysis. A new approach based on lognormal mixture model (LMM) is presented for long-span bridges, where LMM used calculate the structural demand distributions and obtained through cumulative distribution function. To demonstrate feasibility present approach, carried out a suspension bridge with main span 1200m. results show that has higher accuracy than classical approach.

A methodology for Determining the Seismic Vulnerability of Old Concrete Highway Bridges by Using Fragility Curves
Past earthquakes have demonstrated that old RC bridges may be seismically vulnerable. Bridge responses during the last decades illustrated the necessity of the seismic assessment of bridges especially those which were designed with old codes. In this research an existing concrete bridge representative of the most common bridges in the highway system in Iran are studied. Push over and nonlinear ...

متن کاملA Superelastic Retrofitting Method for Mitigating the Effects of Seismic Excitations on Irregular Bridges
Irregularities in bridge pier stiffness concentrate the ductility demand on short piers; while not operating on the longer and more flexible ones. The existence of non-uniform, ductility demand distribution in bridges significantly influences seismic response. As such, this paper proposes a new approach for balancing the ductility demand in irregular bridges by utilizing shape memory alloys (SM...
متن کاملRetrofitted Bridge Fragility Analysis for Typical Classes of Multispan Bridges
Retrofitted bridge fragility curves provide a powerful tool for assessing the effect of retrofit measures on the seismic performance of different bridge types under a range of loading levels. Traditional methods for retrofit assessment typically evaluate the effectiveness of retrofit based on the performance of individual components. However, the use of fragility curves for retrofitted bridges ...
متن کاملAnalytical Fragility Curves for Multispan Continuous Steel Girder Bridges in Moderate Seismic Zones
of bridges are typically based on simplified analyses or empirical data from recent earthquakes. Since earthquake damage data are very scarce in the central and southeastern United States (CSUS), using analytical methods is the only feasible approach to obtain fragility curves. In 1990, bridges in the CSUS began incorporating seismic details. Some of the changes included the component design fo...
