Abstract

The aim of this thesis is to reach in conclusions about the response of existing multistorey reinforced concrete structures, retrofitted by reinforced condrete infill wall and also analytically approach that response computing the characteristic properties of stiffness, strength and deformation capacity of the new composite wall. Moreover, the effectiveness of the connection between the web and the surrounding frame members is under investigetion. For the aforementioned purposes, a 4-storey RC frame converted into slnder wall is constructed and tested by pseudo-dynamic method with substructures. In order to compare the experimental with the analytical results, a non-linear dynamic analysis is conducted and the deformation and stiffness of the specimen are determined by the use of some computtional assumptions, which derive from the computational procedure of the characteristic response parameters of the composite wall. Finally, the overall reliability and correctness of those assumptions is examined through the analytical procedure of a different exprimental project.
