Nonlinear seismic response analysis of steel-concrete composite frames (2008)

Barbato, Michele

Frame finite-element models permit obtaining, at moderate computational cost, significant information on the dynamic response behavior of steel-concrete composite (SCC) frame structures. As an...

Finite element response sensitivity analysis using three-field mixed formulation: General theory and application to frame structures (2007)

Barbato, Michele, Zona, Alessandro, Conte, Joel P

This paper presents a method to compute response sensitivities of finite element models of structures based on a three-field mixed formulation. The methodology is based on the direct differentiation...

FINITE ELEMENT STRUCTURAL RESPONSE SENSITIVITY AND RELIABILITY ANALYSES USING SMOOTH VERSUS NON-SMOOTH MATERIAL CONSTITUTIVE MODELS (2006)

Barbato, Michele, Conte, Joel P

This paper focuses on the effects upon the design point search of gradient discontinuities caused by non-smoothness of material constitutive models in the context of finite element reliability...

Finite element response sensitivity analysis of steel-concrete composite beams with deformable shear connection (2005)

Zona, Alessandro, Barbato, Michele, Conte, Joel P

The behavior of steel-concrete composite beams is strongly influenced by the type of shear connection between the steel beam and the concrete slab. For accurate analytical predictions, the structural...

Finite Element Response Sensitivity Analysis: a comparison between force-based and Displacement-Based Frame Element Models (2005)

Barbato, Michele, Conte, J P

This paper focuses on a comparison between displacement-based and force-based elements for static and dynamic response sensitivity analysis of frame type structures. Previous research has shown that...

Finite element response sensitivity analysis using force-based frame models (2004)

Conte, Joel P, Barbato, Michele, Spacone, Enrico

This paper presents a method to compute consistent response sensitivities of force-based finite element models of structural frame systems to both material constitutive and discrete loading...

Infectious diseases: Further evidence that infection is an infrequent cause of first trimester spontaneous abortion (1996)

Leigh Simpson, Joe, Gray, Ronald H., Queenan, John T., Barbato, Michele, Perez, Alfredo, Mena, Patricio, ...

A previous cohort study found no clinical evidence that infection occurred more often in subjects experiencing pregnancy loss compared with those experiencing success ful pregnancy [Simpson et al...
