Seismic base isolation is a passive structural control system that has been effectively utilized as an innovative seismic-resistant design method in the past decades. The properties of earthquake ground motions have significant effects on response system. Many recent studies were dedicated to influence near-fault seismically isolated buildings. These previous concluded mostly impose larger displacement seismic isolators and, some cases, floor acceleration; furthermore, velocity pulse period...

Energy dissipation devices, including viscous wall dampers (VWDs), are effective for enhancing the seismic performance of buildings. Use VWDs can provide new design opportunities and expand use favorable structural systems such as reinforced concrete (RC) special moment resisting frames (SMRF) taller The objective this paper is to evaluate a prototype 15-story RC SMRF located in area Turkey using compare its response conventional system. It demonstrated that with VWDs, it possible flexible...

Summary Structural design of a 50‐story tall reinforced concrete residential building, which was planned to be constructed in Istanbul and given up afterwards by the investor, has been completed accordance with draft version Seismic Design Code for Tall Buildings that adopts performance‐based seismic as basic approach Initiative Guidelines do. building formed main part structural process due high seismicity proposed location extremely irregular floor plan not conforming usual structures. The...

It is well known that the soil-structure interaction (SSI) changes dynamic response of a structure supported on flexible soil. The analysis optimally controlled SSI systems has certain difficulties due to nature and optimal control problem. In this paper, two-step iteration-based numerical algorithm proposed handle under earthquakes. First, forces are obtained by using fixed-base system. Then, converted frequency domain Fourier transform technique be used in equations lateral displacement...

Seismic base isolation technique has been successfully used to protect structural as well nonstructural components from the damaging effects of earthquakes by reducing floor accelerations and inter-story drifts for many decades. The level acceleration is a key issue in protection acceleration-sensitive components. intensity varies depending on vibration characteristics system. Furthermore, viscous damping devices sometimes are improve performance superstructure ground motions also...

Bir yapı konumunda, taban kayasına ulaşan sismik dalgalar, üstündeki zemin aracılığıyla temele doğru yayılır ve dalganın bir kısmı temel ara yüzünden zemine geri yansırken, diğer ise yapıya iletilir yapının tepesinden tekrar yansır. Bu süreç hem zeminin de dinamik davranış özellikleri ile etkileşim içerisindedir. olayın tamamına Zemin-Yapı Etkileşimi (ZYE) denilmektedir. ZYE hakkında çok sayıda akademik araştırma mevcuttur. Türkiye Bina Deprem Yönetmeliği (TBDY) kazıklı temellerinin deprem...

Turkish Building Seismic Code (TBSC), which was published in 2018 and became effective 2019 prescribes a two-stage loading method for designing of building with rigid podium. In the first stage, podium is modeled as massless structure only mass superstructure considered modal response spectrum analysis. The seismic design forces are computed using this model appropriate modification coefficient overstrength factor. second system addition, superposed those Due to use separate models analyses...

Seismic codes generally require that the Equivalent Load Method or Modal Response Spectrum is adopted in design of buildings. In equivalent seismic load method, static force applied to building determined depending on seismicity region where located, usage class building, fundamental period and mass. Later, this reduced by reduction factor take into account increase capacity system decrease demand due nonlinear inelastic behavior system, i.e., accepting limited deformations subjected...
