Combined effects of infill walls and steel bracings in seismic response of rc buildingsCombined effects of infill walls and steel bracings in seismic response of rc buildings Πλήρης Δημοσίευση σε Συνέδριο Conference Full Paper 2015-10-082014enThe present study is focused on seismic vulnerability assessment and retrofitting of typical reinforced concrete (RC) buildings that were designed and constructed according to the common practice and simplistic provisions in 60's and 70's in Greece as well as in other seismic prone European countries. For this purpose, the characteristic SPEAR building was chosen that has been extensively examined experimentally and numerically. The examined modes of this structure include infill panels and additional steel bracings in selected bays of the frame, thus, several modelling scenarios were considered consisting of variant arrangements of infill panels and brace members. Response parameters are analysed (mainly concerning the global behaviour of the structure) to investigate the sensitivity of the results when adopting various values of the mechanical parameters of infill walls which have many inherent uncertainties, hence, creating difficulties in obtaining realistic results. The impact of the combined action of infill walls and steel bracings is thoroughly investigated through non-linear static (pushover) analyses. http://creativecommons.org/licenses/by/4.0/2nd European Conference on Earthquake Engineering and Seismology Yiannis Tsompanakis Anastasios Andreadakis Networks, Seismic seismic networks networks seismic Waves, Seismic seismic waves waves seismic
