摘要

For reconstruction of multi-layer concrete panels special bonded anchors are used to secure the outer leaf. If those sandwich walls (see fig. 1.) are reconstructed without an additional insulation, thermal induced constraining stresses have to be considered. A static model will be suggested, which enables the calculation of the thermal constraining forces by considering the concrete stretch stiffening's positive effect. Different fixings are used for taking compression caused by negative wind tension. The buckling model is based on the permissible pressure loads of the respective approvals. Both static models serve as base for the proofs of the ultimate limit states and are applied on a recent refurbishment of a office building. The figure below shows the build-up of the existing sandwich wall where the reason of the required refurbishment is obvious.
