Abstract
An in-plane finite element model of infilled frame systems is formulated. A frame–infill interface capable of transferring only normal compressive contact forces is defined. The complex phenomenology affecting these systems is explored, with a focus on the contact/separation conditions at the interface. Comparisons with previously reported experimental and numerical findings are made, and the model is validated. Parametric analyses are performed. Interpolation formulae are determined, which estimate frame–infill contact lengths and global stiffness in the elastic regime.File in questo prodotto:
