limit state sensitivity analysis of gravity type quaywalls according to AYGM Technical Code for Coastal and Port Structures in Seismic Zones (2008)
Öz
In this study, stability of a monoblock gravity type quaywall was
studied based on the traditional pseudo-static approach as suggested by AYGM
Technical Code for Coastal and Port Structures in Seismic Zones (2008).
Sensitivity of design parameters to the stability of a generalized structure is
analyzed. Variability of the critical structure dimensions to the variability
of the design parameters in terms of sliding and overturning is studied.
Controlled (CD) and Minimum Damage (MD) performance levels were considered in
the evaluation of the results. Results indicated that overturning criteria
limits the structure dimensions for relatively small horizontal seismic
coefficient (kh) values, while the structure dimensions are limited
by the sliding criteria for relatively high values of kh. Friction
coefficient is found to be effective on the critical failure mode. Higher
values of friction coefficient causes a transition from overturning mode to
sliding mode at higher values of kh which results with smaller
structure dimensions.
