摘要

A methodology for building 3D non-linear finite element models has been defined, validated and applied, to simulate the longitudinal sliding failure mechanisms of composite slabs, for several commercial and own designs. Sensibility of shear resistance is analysed, mainly in relation to: friction coefficient, embossing depth and slope, shell thickness, inclination angle and length of embossment and profiling angle of rib shape. The model simulates locally the longitudinal shear failure in "pull-out" test. Concrete is treated as a rigid contact surface; steel is implemented using a multilinear plasticity model. Predominant effect is sliding with friction; so contact elements are implemented with appropriate friction coefficient. Conclusions of the parametrical analyses are summarized, regarding to as design as general behaviour matters.
