Investigation of structural irregularities of reinforced concrete buildings according to 2018 Turkish Building Earthquake Code

In this study, analyses and designs of three different building and structural system groups with the same floor plan and spans have been carried out according to the Turkish Building Earthquake Code 2018 (TBDY 2018). Preliminary sizing has been performed for all three examples. In the first example, a 10-story building with a pure frame structural system, the column and beam dimensions were adjusted to reduce the dominant vibration period, making the system compliant with the conditions specified by the Equivalent earthquake load method. In the second example, a 11-story reinforced concrete frame and shear wall mixed system were analyzed according to the equivalent seismic load method. In the third example, a building with a height class (BYS) of 1, according to TBDY 2018, was analyzed using the modal superposition method. All three examples' modeling, and analysis were done using the SAP2000 software package.
