A case study of comparative seismic assessment of reinforced concrete structures using rapid visual screening methods

Abstract

<p><strong> Abstract</strong></p><p>Since earthquake-induced damages have been escalating in recent years, and some structures built in Europe are designed without considering seismic design standards or with considering moderate design standards, seismic evaluation of existing buildings is required to perform (Aftabur & Shajib, 2012; Valentina et al., 2018). Determining safety level of existing buildings and performing appropriate precautions is essential not only to prevent possible life-threatening issues but also to minimize economic losses. There are various methods for determining seismic safety of existing structures. Among these methods, detailed seismic assessment methods are challenging to implement; however, Rapid Visual Screening (RVS) methods are capable to applied relatively simply and in a short time to assess large building stocks. Therefore, existing buildings are needed to be inspected by RVS procedures in order to take necessary precautions before an impending earthquake. This study compares performance of 20 Reinforced Concrete (RC) residential buildings in Gyor, Hungary, by employing FEMA P-154, JBDPA and RISK-UE RVS methods. The assessment results provide a comparison of the employed methods to identify building damage state and provide the insight needed to decide whether additional existing buildings should be examined in order to reduce earthquake-induced damage.</p><p> </p><table><tbody><tr><td> <p><strong>Keywords:</strong></p> </td> <td> <p>Rapid Visual Screening; Reinforced Concrete Buildings; Seismic Assessment; Gyor</p> </td> </tr></tbody></table><p> </p><p> </p><p><strong>References</strong></p><p>Aftabur, R., & Shajib, U.

Pushover Analysis in Seismic Engineering: A Detailed Chronology and Review of Techniques for Structural Assessment

“…As computational technology advances, more sophisticated nonlinear analysis procedures, such as nonlinear response history analysis (NLRHA), have become feasible but remain computationally intense and time-consuming [32]. In response, pushover-based methodologies, such as the N2 method, the capacity spectrum method (CSM), and the displacement coefficient method (DCM), have emerged as efficient, simplified alternatives that use empirical approaches to directly estimate seismic demand and capacity, thereby reducing computational burdens [2,33,34]. The N2 method provides a simplified estimation of seismic demands based on a plastic hinge analysis approach, the CSM uses a capacity spectrum to assess structural response, and the displacement coefficient method estimates seismic demands based on displacement coefficients derived from experimental data [2][3][4].…”

Investigasi Visual Kelayakan Bangunan Publik di Desa Jamblang

“…berbagai macam bencana hingga saat ini oleh karena itu perlu dilakukan pengecekan khususnya terhadap komponen struktural untuk mengetahui tingkat kerusakan akibat pasca bencana. Investigasi struktur untuk bangunan tua perlu dilakukan untuk meninjau tingkat keamanan bangunan yang ada dan melakukan tindakan pencegahan yang tepat sangat penting mencegah kemungkinan masalah yang mengancam (Bektaş & Kegyes-Brassai, 2022). Pengamatan visual merupakan suatu tahapan awal untuk mendefinisikan permasalahan atau kerusakan pada suatu bangunan gedung, dan keselamatan pengguna bangunan.…”
