Stability Analysis of the Historic Masonry Storefront

Since 1910, the building "Römischer Hof" has been shaping the cityscape with its neo-classical multi-leaf sandstone-brick-masonry at the Berlin Boulevard "Unter den Linden". According to the construction plan, the historic core of the building was deconstructed and replaced by a modern reinforced concrete structure. The landmarked facade was integrated in the new load bearing system. Using high quality non-linear finite-element-computations, Dynardo could prove the stability of the multi-leaf facade. Detailed 3D models and powerful elasto-plastic material models obtained a design particularily regarding an optimal load distribution between the new and old structures as well as an economic space management.

Dynardo constructed detailed 3D-models of the single areas of the facade in which the multi-leaf construction of the historic masonry was taken into account. Furthermore, the creep deformation of the new construction was determined in the 3D-model.

The specific material parameters as a prerequisite for the computation were based on extensive material testing. Dynardo developed high-capacity elasto-plastic material models for close to reality description of material and crack behaviour of single-leaf and multi-leaf masonry.
