Estimation of fundamental periods of shear-wall dominant building structures

Balkaya, C
Kalkan, E
Shear-wall dominant multistorey reinforced concrete structures, constructed by using a special tunnel form technique are commonly built in countries facing a substantial seismic risk, such as Chile, Japan, Italy and Turkey. In spite of their high resistance to earthquake excitations, current seismic code provisions including the Uniform Building Code (International Conference of Building Officials, Whittier, CA, 1997) and the Turkish Seismic Code (Specification for Structures to be Built in Disaster Areas, Ankara, Turkey, 1998) present limited information for their design criteria. In this study, consistency of equations in those seismic codes related to their dynamic properties are investigated and it is observed that the given empirical equations for prediction of fundamental periods of this specific type of structures yield inaccurate results. For that reason, a total of 80 different building configurations were analysed by using three-dimensional finite-element modelling and a set of new empirical equations was proposed. The results of the analyses demonstrate that given formulas including new parameters provide accurate predictions for the broad range of different architectural configurations, roof heights and shear-wall distributions, and may be used as an efficient tool for the implicit design of these structures.

Experimental investigation of the seismic behaviour of panel buildings
Yüksel, S. Bahadır; Atımtay, Ergin; Department of Civil Engineering (2003)
Shear-wall dominant multi-story reinforced concrete structures, constructed by using a special tunnel form technique are commonly built in countries facing a substantial seismic risk, such as Chile, Japan, Italy and Turkey. In 1999, two severe urban earthquakes struck Kocaeli and Düzce provinces in Turkey with magnitudes (Mw) 7.4 and 7.1, respectively. These catastrophes caused substantial structural damage, casualties and loss of lives. In the aftermath of these destructive earthquakes, neither demolished ...
Comparison of mean site-specific response spectra in Turkey with the design spectra of AASHTO
Mestav Sarıca, Gizem; Askan Gündoğan, Ayşegül; Department of Civil Engineering (2014)
Seismic design of bridges is a significant problem for all seismically-active countries including Turkey which has gone through recent destructive earthquakes. Bridges are important elements of transportation and their robustness is important in the aftermath of major earthquakes. Turkish engineers currently employ a modified version of AASHTO (American Association of State Highway and Transportation Officials) LFD Design Specifications for bridge design. Within the scope of a national project (TÜBİTAK 110G...
Assessment of tunnel induced deformation field through 3-dimensional numerical models (Necatibey subway station, Ankara, Turkey)
Aktürk, Özgür; Doyuran, Vedat; Department of Geological Engineering (2010)
In heavily settled areas, deformations induced by the tunnel excavation may cause serious damage to nearby structures. In this study it is aimed to model ground deformations induced by main tunnels and connection tunnels excavations as well as groundwater drainage. Therefore, it is necessary to study effective means of controlling tunnel induced deformations. The main parameters affecting the failure and deformation state of the soil around a circular underground opening are the physical characteristics of ...
Evaluation of performance based displacement limits for reinforced concrete columns under flexure
Solmaz, Taylan; Yakut, Ahmet; Department of Civil Engineering (2010)
Reinforced concrete frame buildings are the most common type of constructions in Turkey which are exposed to various types of forces during their lifetime. Seismic performance of reinforced concrete frame buildings is dominated by columns which can be classified as primary members of these structures. When current codes are considered, all of them contain several provisions in order to implement reliable seismic performances of reinforced concrete columns. In order to evaluate the accuracy of these provisio...
Assessment of twin tunnel induced ground deformation by empirical and numerical analyses (Eurasia tunnel: NATM part, Istanbul, Turkey)
Ağbay, Ebru; Topal, Tamer; Department of Geological Engineering (2019)
Pre-support systems become very important for inner-city shallow tunnels especially while applying New Austrian Tunneling Method (NATM) which requires some deformation to relieve the stress. Previous studies about assessing the magnitude of surface displacements caused by twin tunneling do not include the effects of presupport system and stress release by deformation. Moreover, most of the established empirical equations were obtained by using data from tunnel passing through clayey soil. Objective of this ...
