Assessment of Unreinforced Masonry Structures Under Extra Ordinary Horizontal Action

Masonry is a heterogeneous, discontinuous and anisotropic material with preferable rupture or stress surfaces. The mechanical properties of such a system are largely influenced by its forming materials and by construction method. Thus, the type of masonry units, construction method and material properties influences the performance of URM against lateral loads. Masonry failure due to lateral loads is characterized by the heavy weight, high stiffness and low tensile strength. The global stability of URM depends on the behavior of individual elements in a structure.

The aim of this project is to introduce the participants into advanced requests in the field of URM buildings under horizontal monotonic action causing damages (like earthquake and tsunamis). The studies will be concentrated on a URM building under 3D action.

Participants will get in touch with the theory of equivalent frame approach, definition of non-linear properties for different failure types, evaluation of damage grades according to EMS-98 and other limit state definition as well as check of drift limits under the consideration of different vertical and horizontal load pattern. The participants will assess performance of a 3D multi-story building (using SAP2000) and evaluate its resistance with respect to the different types of applied horizontal action. Participants will also discuss the difficulties, advantages and disadvantages of equivalent frame approach in correlation to building information models (BIM).

This course will be intensively assisted by the staff of the Chair of Advanced Structures.
