Fatigue reliability of a stiffened panel subjected to correlated crack growth
Fatigue reliability Stiffened panel Crack growth Inspection Reliability updating
2012/4/26
The objective of this work is to analyze the fatigue reliability of a stiffened panel subjected to the growth of correlated cracks. A probabilistic crack growth model is applied, allowing for the exis...
Stiffened Coupled Shear Walls on Elastic Foundations with Flexible Connections and Stepwise Changes in Width
Coupled shear wall Elastic foundation Stiener flexible connection Continuous connection
2009/10/13
The exceedingly large top drift and bottom bending moment due to the weakening of shear walls in tall buildings by door, window and corridor openings is one of the most frequently encountered problems...
Development of a Set of Simple Formulae for Estimation of Ultimate Strength of a Continuous Stiffened Panel under Combined Loads
Simple Formulae Continuous Stiffened Panel Combined Loads FEM
2009/4/30
The authors proposed a set of closed-form simple formulae to estimate the ultimate strength of a continuous stiffened panel under combined biaxial thrust and lateral pressure. This paper extends the a...
A study on fatigue crack propagation in longitudinal stiffeners of ship structures-An analysis of multiple cracks propagation in 3-dimensional stiffened panel structures
fatigue crack propagation longitudinal stiffeners ship structures 3-dimensional stiffened panel structure
2009/4/30
In ship structures, fatigue cracks may initiate at the intersection between face plates of the longitudinals and web stiffeners attached to the transverse girders. These cracks may propagate in web pl...
General Buckling Strength of Ring-Stiffened Cylindrical Shells under External Pressure and Effective Breadth of Ring-Stiffeners
External Pressure Effective Breadth
