Steel concentrically braced frames (CBFs) are frequently used as efficient lateral load resisting systems to resist earthquake and wind loads. This paper focuses on high seismic applications where the brace members in CBFs dissipate energy through repeated cycles of buckling and yielding. Widely-used seismic provisions have somewhat different approaches for the seismic design of CBFs. The present study evaluates in detail the similarities and differences between the design philosophies and provisions used i...
Seismic velocity characterisation and survey design to assess CO2 injection performance at Kizildere geothermal field

The noncondensable gases in most geothermal resources include CO2 and smaller amounts of other gases. Currently, the worldwide geothermal power is a small sector within the energy industry, and CO2 emissions related to the utilisation of geothermal resources are consequently small. In some countries, however, such as Turkey and Iceland, geothermal energy production contributes significantly to their energy budget, and their CO2 emissions are relatively significant. SUCCEED is a targeted innovation and resea...
Seismic performance evaluation of eccentrically braced frames with long links using FEMA P695 methodology
Balıkçı, Elif Müge; Al-Janabi, Musab Aied Qissab; Topkaya, Cem (2022-05-01)
© 2022 Elsevier LtdShort links that primarily yield under shear are usually preferred in eccentrically braced frames (EBFs) due to their high rotation and energy dissipation capacities. Long links that yield under flexure can be used in cases where large openings are required for architectural reasons. Research conducted in the past showed that the seismic response factors recommended in ASCE7 result in designs with higher collapse probabilities than expected for EBFs with shear links. Long link behavior di...
Seismic behavior assessment of low-rise reinforced concrete structural walls using quasi-static reversed cyclic loading protocol
Ezzatfar, Pourang; Canbay, Erdem; Özcebe, Güney; Department of Civil Engineering (2016)
The reinforced concrete shear walls of low- to mid-rise residential buildings, having height to length ratio ranging from 1 to 3, are more of a concern in research studies in recent years. Since the failure mode of these walls depends on the interaction between shear and flexural action, predicting the failure mode of this type of shear walls is not straight forward. While seismic behavior of highrise walls (i.e. aspect ratio greater than about 3) is almost known and theoretical assumptions matches well wit...
Seismic damage assessment based on regional synthetic ground motion dataset: a case study for Erzincan, Turkey

Estimation of seismic losses is a fundamental step in risk mitigation in urban regions. Structural damage patterns depend on the regional seismic properties and the local building vulnerability. In this study, a framework for seismic damage estimation is proposed where the local building fragilities are modeled based on a set of simulated ground motions in the region of interest. For this purpose, first, ground motion records are simulated for a set of scenario events using stochastic finite-fault methodolo...
