Comparison of TEC (2007) and TBEC (2018) Earthquake Codes in terms of Section Damage Limits

Abstract

In order to determine the earthquake safety of an existing or new structure, it is necessary to first determine the cross-sectional damage level of each bearing element. For this purpose, the structure to be determined for earthquake safety is first analyzed with one of the nonlinear assessment methods. The damage level of the section is obtained by comparing the strain value of the cross section with strain upper limit values which is the value corresponding to the level of cross-sectional damage in the code in force. Therefore, it is extremely essantial to obtain accurate cross-sectional damage limit values in determining earthquake safety of buildings. In this study, Turkish Building Earthquake Code (TEC, 2007) which was used to evaluate earthquake safety of existing buildings before 2019 and Turkish Building Earthquake Code(TBEC, 2018) which was started to be used since the 2019 were compared in terms of section boundaries damage. For this purpose, one beam, column and shear wall section were determined. Two types of material groups were selected: low quality to reflect existing structures and good quality to reflect new structures for comparison of codes. In low quality material group; concrete grade C10, reinforcement grade S220, structural bearing tie densification at 250 mm and non- distence piece was selected. In high quality material group; concrete grade C25, reinforcement grade S420, structural bearing tie densification at 10 mm and the presence of sufficient distence piece was selected. In addition, 3 different axial load levels were determined for column and shear wall sections. Then, the upper limit values of the strains corresponding to the cross-sectional damage level of totally 14 section were obtained based on the TEC (2007) and TBEC (2018) earthquake codes by analysing each of axial load levels. Cross-sectional damage levels were determined depending on the resulting strain upper limit values and were shown on the moment curvature plots. The results determined according to both codes were compared with each other.
