Avaliação da não linearidade fisica na estabilidade global de edificios de concreto armado

TL;DRAbstract

In this work, are presented the mathematic expressions necessary for determinate the moment of inertia in function of the curvature for rectangular cross-section the reinforced concrete submitted to mono-axial eccentricity.The expressions are determinate by the integration of analytic parabola rectangle stress strain diagram of concrete.Based in these expressions a computer system was developed to calculate the inertia of moment curvature.The objective is to get the moment of real inertia to be used in the verification of the deformations.It is necessary that the computer system know: geometry, the disposal of the bars, the characteristics of the materials and operating requests in the section.When the database is imputed it is possible to have a control over the method of partial factors of materials and solicitations.For the elasticity model may be adopt the NBR6118's values, or another value that must be informed.The resistance tension of concrete was rejected.To make the validation
