A stochastic framework is developed, in terms of the theory of homogeneous random functions, to estimate the seismic hazard associated with linearly extending seismic sources. The formulation is carried out in the space-time domain. An earthquake having at least a magnitude of m is assumed to occur whenever the total strain energy accumulated over the potential rupture plane exceeds the energy level corresponding to this magnitude, m. An alternative formulation, in which an earthquake is generated when the total shear force exceeds the total static friction force developed over the ruptured portion of the fault plane, is also described.


A simplified non-linear procedure for buildings with shear walls
TEKELİ, Hamide; Atimtay, Ergin (Thomas Telford Ltd., 2015-01-01)
A simple and easily applicable analytical method is proposed to obtain the capacity curve of buildings with shear walls as the first stage of a seismic pushover analysis. The method is based on controlling the curvature distribution of shear walls. Accuracy of the method was examined based on data of three sample buildings compiled from the literature. The buildings have different floor areas, number of storeys and cross-sectional areas of shear walls. The method can be economically used with respect to bot...
An alternative frame-shear wall model: continuum formulation
KAZAZ, İLKER; Gulkan, Polat (Wiley, 2012-07-01)
The basic assumption of the analysis of wall-frame structures is that two dissimilar structural systems, deforming in shear and flexural modes, are constrained to act together. The same set of boundary conditions is also assumed to be applicable to both types of components. An inconsistency arises when the rotation at the lower end of the combined beam is assumed to be zero because this boundary condition is applicable only to the flexural component of deformation. For the shear component that is related to...
Probabilistic assessment of earthquake insurance rates for important structures: Application to Gumusova-Gerede motorway
Yücemen, Mehmet Semih; ERDİK, MUSTAFA ÖZDER (Elsevier BV, 2008-01-01)
A probabilistic model is presented for the assessment of the earthquake insurance rates for important engineering structures, for which the seismic losses could be quite significant. The proposed model is used to estimate the earthquake insurance premiums for the structures taking place in the Bolu Mountain Crossing in the Gumusova-Gerede motorway Section, Turkey. The model requires two types of studies, namely: seismic hazard analysis and estimation of potential damage to structures based on damage probabi...
Seismic Performance Assessment of Masonry Buildings Using In Situ Material Properties
Cobanoglu, Baran; ALDEMİR, ALPER; Demirel, Ismail Ozan; Binici, Barış; Canbay, Erdem; Yakut, Ahmet (American Society of Civil Engineers (ASCE), 2017-08-01)
Seismic performance assessment of existing buildings requires the existing material's properties to be determined as this has a significant influence on the seismic risk. As one of the most common construction type in Turkey, masonry buildings are assessed generally based on the recommended material properties specified in relevant codes as opposed to testing of samples taken from the existing buildings. However, due to different material types and workmanship quality, the specified properties might be quit...
A New Method for Prediction of the Transient Force Generated by a Liquid Slug Impact on an Elbow of an Initially Voided Line
KAYHAN, Bulent A.; Bozkuş, Zafer (ASME International, 2011-04-01)
The aim of the present study is to predict the impact force applied by an individual transient liquid slug on an elbow at the end of a horizontal and initially empty pipeline. The liquid slug is driven by pressurized air in a tank located upstream of the pipeline. The time dependent pressure distribution along the elbow and a vertical extension segment after the elbow are solved with a 1D numerical approach along a curved line mesh. An assumed and calibrated axial turbulent velocity profile function with 3D...
