Seismic Assessment of Tall Buildings Designed According to the Turkish Building Earthquake Code

For the first time, 2018 edition of Turkish Building Earthquake Code has added a dedicated chapter for design high-rise buildings in earthquake-prone areas. Keeping view widely practised option rigid shear walls at centre structure, latest code additionally defined limits shear-wall axial forces buildings. The new force have not been independently investigated optimal and criticality. This calls detailed investigation newly Turkey, where seismic activity historically remained high. study, therefore, investigates effect variation limit values wall on collapse prevention such A building designed entirely according to was chosen as base model. location is Istanbul, which highest number tall compared other cities Turkey. total 7 alternative models were created by changing concrete material class thickness walls. approach allowed us quantify its criticality against another important consideration, i.e., compressive strength concrete. Forty different earthquake ground motion records used analyse determine how critical ratio terms probability. method proposed Federal Emergency Management Agency (FEMA) document FEMA P695 followed levels structures. nonlinear analysis performed failure safety models. Results indicate that an increase or decrease ratios more than 15% renders structure either overdesigned deficient. Doi: 10.28991/CEJ-2022-08-03-011 Full Text: PDF
