PBO textile embedded in FRCM for confinement of r.c. columns
2014
Results of experimental tests on two reinforced concrete columns confined with PBO-FRCM jacketing subject to axial load and bending moments are presented, showing the effectiveness of the confinement system. Comparison of test results against theoretical results derived by a fiber model stress the ability of the confinement system to enhance both strength and deformation capacity of the confined concrete
SHEAR STRENGTH DEGRADATION DUE TO FLEXURAL DUCTILITY DEMAND IN R.C. ELEMENTS
2014
A proposal is formulated that allows to evaluate the residual shear strength of reinforced concrete columns and beams for an assigned flexural ductility demand by limiting the range of the deviation angle between the inclinations of the yield and the crack lines. In order to take into account the degradation due to cyclic loads, the reduction of the range of the deviation angle is related to the value of cinematic ductility
Seismic response of steel frames with reduced beam sections
2003
This study concerns the effectiveness of weakening on the beams of fully and partially restrained connection steel frames in order to locate plastic hinges far from the joints. Two types of non-linear analysis, for geometry and constitutive law are developed: static pushover analysis, in which the structure is subjected to constant vertical loads and to horizontal loads linearly increasing up to collapse; and incremental dynamic analysis, in which the structure is subjected to uniformly scaled ground motions. Applications for four-bay frames with three and nine stories designed according to the EC3 code and for Italian 1st-category seismic areas are developed in order to evaluate the influe…
Un sistema Jurídico más sofisticado en el Neoconstitucionalismo
2011
El texto aborda la evolución y algunas de las alteraciones que ha experimentado el sistema jurídico en el neoconstitucionalismo, relacionadas en buena medida con la ductilidad que viene a presentar su legislación, pero también con la complejidad que adquiere la tarea judicial, la aplicación e interpretación de las normas del Derecho, en este modelo diferente de Estado de Derecho que representa el actual Estado Constitucional.ABSTRACT This text analyzes the evolution and alterations in legal system of Constitutional State. These alterations consist in ductility in the legislation. But, also, these alterations consist in complexity assumed by the judicial function, application and interpretat…
