Eriksson Wall offers the use of a beam-spring model to perform the analysis of insulated wall panels. The model is based on Dr. Maguire’s research presented in “Generalized beam-spring model for predicting elastic behavior of partially composite concrete sandwich wall panels.’ Note that this paper does not propose a new modeling method, but instead verifies an existing analysis procedure for use with insulated wall panels. The current analysis feature is only valid for uncracked panels. Any paneling cracking will have to be checked by the user.
This procedure uses data obtained from the double shear test, or 5-layer shear test, to model the composite connectors. The double shear test results in a bi-linear curve relating the shear deformation in the connector to the force generated in the connector. The connector producer will provide the bi-linear curve data, strength reduction factors to be applied to the data, and allowable limit states for the connectors.
