Calculate bridge-specific fragility curves

1. Number of spans

Number of bridge spans

2. Span Lengths (m)

Complete the length of every span from left to right in (m) separated with semicolon. e.g. for a bridge with 3 spans having lengths 25m, 45m, 25m complete with the following : 25;45;25

3. Meshsize for every span

Select meshsize for every span. e.g. for a bridge with 3 spans if the meshsize for every span is 10 complete with the following : 10;10;10

4. Distributed Span Load (G+0.2Q) (kN/m²)

Assign the distributed load at every span (combination G+0.2Q). e.g. for a bridge with 3 spans if the distributed load for the G+0.2Q combination is 30.3kN/m2 complete with the following : 30.3;30.3;30.3

5. Pier Height

For all piers from left to right complete the pier heights in (m). e.g. for a bridge with 3 spans and 2 piers with heights 20m(left pier) and 25m(right pier) complete with the following : 20;25

6. Deck Geometry

Complete the deck geometry first at span and then at support location. The sequence should be the following:
A(m²)_,span ; J(m⁴)_,spanx0,1 ; Iz(m⁴)_,span ; Iy(m⁴)_,span ; E(kN/m²) ; A(m²)_,supp ; J(m⁴)_,suppx0,1 ; Iz(m⁴)_,supp ; Iy(m⁴)_,supp
e.g.
6.32 ; 0.15 ; 2.82 ; 80.51 ; 35000000 ; 9.08 ; 1.5 ; 3.73 ; 111.76

7. Number of eigenmodes

Complete the number of eigenmodes to be considered.

8. Direction of loading

Select the direction of loading, x-longitudinal or y-transverse based on the figure.

9. Damping

Select the damping value e.g. for ζ=5% write 0.05.

10. Pier to Deck Connection

11. b_tot (LS1, LS2, LS3, LS4)

Complete the dispersion value for every limit state (LS1, LS2, LS3, LS4) as described in: Stefanidou S, Kappos A (2017) Methodology for the development of bridge-specific fragility curves Earthq Eng & Struct Dyn 46:73-93, DOI: 10.1002/eqe.2774 , separated with semicolon e.g. 0.55;0.65;0.75;0.85.

12. Component Threshold Values

Select default (according to Stefanidou Kappos, EESD, 2017) values for component thresholds, or used defined (to be competed in the relevant forms for every component)
