heal.abstract	Masonry infill walls are commonly used in the frames of reinforced concrete (RC) buildings around the world. However, their contribution to the seismic analysis is ignored since they are defined as “non-structural” elements by modern codes. Masonry infill walls have a direct impact on the seismic response of RC frames but that impact cannot be assumed as purely positive or negative. Distribution of infill walls plays an important role on the resistance of the frame under seismic loads. Non-uniform distribution along the length or the height of the building may lead to undesirable seismic performance of the structure. In 2008, mr. Stathopoulos Charalampos, civil engineer NTUA, investigated the seismic performance of a typical 5-storey RC frame designed following the 59 Seismic Code ([2]). The length of the infill wall bay was 3.20m and the height was equal to 2.5m. Motivated by this, the present thesis focuses on the evaluation of the effect of infill walls on seismic performance of two 7-storey RC frames of different dimensions and different infill wall bay length. More specifically, the first frame considered, is designed following the 85 Seismic Code, while the second one following the Greek Seismic Code (E.A.K). The dimensions of both RC frames differ along the frame height. Regarding the frame of 70s, the infill wall length of the 1st and 4th bay in the ground floor is equal to 4.975m, while of the 2nd and 3rd is equal to 5.10m. Regarding the frame of 90s, the infill wall length of the 1st and 4th bay in the ground floor is equal to 5.20, while of the 2nd and 3rd is equal to 5.30m. The reinforcement used in both frames was stronger coMPared to the frame studied by Stathopoulos. For both RC frames, the performance under the action of seismic loads is investigated applying Pushover Analysis. The results of the analysis for both frames of the 70s and the 90s are coMPared as well as the results for the cases of a) bare frames b) fully in-filled and c) PILOTIS. The implementation of all the above is achieved applying a general purpose finite element program (LS DYNA). LS DYNA has been developed by the former Livermore Software Technology Corporation (LSTC) and it is used by researchers as well as by industry individuals.	en
