Following the earthquake sequence affecting southeast Turkey in 2023, a team led by Committee 133 of the American Concrete Institute surveyed nearly 250 reinforced concrete buildings in the area extending from Antakya to Malatya. Buildings ranging from 2 to 16 stories were surveyed to assess their damage and evaluate the robustness of their structures in relation to overall stiffness, as measured by the relative cross-sectional areas of structural walls and columns. The majority of the buildings were estimated to have been built in the past 10 years. Yet, the structures surveyed were observed to have amounts of structural walls and columns comparable with amounts reported after the Erzincan (1992), Duzce (1999), and Bingol (2003) Earthquakes in Turkey. These amounts are, on average, much smaller than the wall and column amounts used in Chile and Japan. Because of that lack of robustness and given the intensities of the motions reported from Antakya to Malatya (with 10 stations with peak ground velocity (PGV) of 100 cm/s or more), it is concluded that structures in this region experienced large drifts. Excessive drift (1) exposed a myriad of construction and detailing problems leading to severe structural damage and collapse, (2) induced overturning caused by p-delta for some buildings, and (3) caused widespread damage to brittle masonry partitions. The main lesson is simple: ductility is necessary but not sufficient. It is urgent that seismic drift limits are tightened in high-seismicity regions worldwide. © The Author(s) 2024.Conference Object Citation - Scopus: 3Izmir Municipality Housing and Zoning Code Analysis and Representation for Compliance Checking(Universiteit Twente, 2013) Macit, Sibel; İlal, Mustafa Emre; Günaydın, Hüsnü Murat; Suter, GeorgSystems for code compliance checking of building projects require representation of building codes. Building codes are complex, and the development of computer implementable representations is challenging. As a case in point, this paper reports on experiences gained while modeling ̄zmir Municipality Housing and Zoning Code (IMHZcode). First, IMHZcode was analysed to understand the various types of information contained in it in order to develop a comprehensive building code model. The rules were classified according to their formalizability and self-containedness. Then, existing modeling approaches were evaluated to find the most convenient method that meets the needs for modeling IMHZcode. A key criterion used in this evaluation was ease of maintenance by non-programmers. The paper concludes with an illustrative example of the selected methodology's application within the context of IMHZcode.
