[automatically translated] The behavior of the frame buffered mesh is influenced by many factors, which make problematic the prediction of the response variables under lateral loads, from the difficulty of selecting information from the experiments to define parameters useful to a calculation model. The models based on the definition of equivalent diagonal struts to the rear-end collision simplify the problem as long as we are content to predict the response of the system in global terms, having under observation such significant quantities the lateral stiffness, strength and ductility (ch. 3). However, all the experimental experiences, including those described in the previous chapter, show that even in a simplified model must be defined: - the section of the strut; - The initial stiffness consequent to its elastic property and a law that describes the cyclic degradation; - The initial resistance of the system and an envelope curve that will reduce the value of displacement in relation to the level reached; The following describes the procedures followed for the definition of an equivalent strut model showing how the data collected from the experiment are used for its calibration.
