The improvement of understanding structural capacity against large displacement demand of near-fault conditions has become a subject of research interest for the last decade. Parallel to the developments in performance-based seismic design (PBSD) this issue has attracted researcher interest further, as assessment of structural displacement capacity has become one of the main issues for the procedures employed in this new concept. This study focuses on the near-fault ground motion demand on framed structures. We have used soil site, near-field records from various M > 6.5 events including the 1999 Turkey and Taiwan earthquakes. The spectral quantities were computed using a ground motion prediction relationship that is based partly on these near-fault ground motion records. The spectral quantities were evaluated for the global displacement demand definition of such ground motions. We employ this global demand definition to calculate the distance and magnitude dependent inter-story drift demand limits for frame-type structures. Comparison of these preliminary findings with code provisions is encouraging.

Near-fault ground motions: Demand and structural capacity requirements Gulkan, P; Akkar, Dede Sinan (2001-11-27) The improvement of structural capacity against large displacement demand of near-fault ground motions has been the subject of research for the last decade. Parallel to the developments in performance-based seismic design (PBSD) this issue has attracted researcher interest further, as assessment of structural displacement capacity has become one of the main concerns for the procedures employed in this new design concept. This Chapter focuses on the near-fault ground motion demand and corresponding structural...
Peak ground velocity sensitive deformation demands and a rapid damage assessment approach Akkar, S; Sucuoğlu, Haluk (2003-05-13) The effect of peak ground velocity (PGV) on the maximum inelastic deformation demand of simple, non-degrading structural systems is studied. Ground motion data sets are assembled for pre-defined ranges of PGV and they are used to conduct nonlinear response history analysis of single-degree-of-freedom (SDOF) systems. The study is focused on short and intermediate periods of vibration (T) and strength reduction factor (R) is used to define the lateral capacity of the structure. As part of the study, a simple ...
Investigation of the particle breakage parameters in locked-cycle ball milling Acar, Cemil; Hoşten, Çetin; Department of Mining Engineering (2012) Size reduction processes, particularly fine grinding systems, in mineral processing and cement production plants constitute a great portion of energy consumption and operating costs. Therefore, the grinding systems should be designed properly and operated under optimum conditions to achieve productive and cost effective operations. The use of simulation based on kinetic mathematical models of grinding has proven useful in this respect. The kinetic models contain two essential parameters, namely, breakage ra...
Improvement in dye sensitized solar cells from past to present Mohiuddin, Obaidullah; Obaidullah, Madina; Sabah, Cumali (Springer Science and Business Media LLC, 2018-10-01) Several emerging renewable technologies are available to satisfy the current energy demand and to minimize the effect of environmental degradation caused by high consumption of fossil fuels. These technologies are not mature enough to solve this problem but require more time for improving the efficiency, and cost reduction to become the economical alternative of fossil fuels. In this paper Dye-sensitized solar cell (DSSC) has been discussed in detail owing to advancement in the technology. Since each compon...
An energy-based seismic response evaluation of simple structural systems with simulated ground motions Karimzadeh, Shaghayegh; Ozsarac, V.; Askan, A.; Erberik, Murat Altuğ (Earthquake Engineering Research Institute; 2018-01-01) In recent years, there has been a strong interest on energy-based design and assessment methods for structural systems. The underlying research has been mostly performed using real ground motion records taken from existing earthquakes worldwide. Results may involve bias due to lack of homogeneity of the available ground motion dataset in terms of magnitudes, source to site distances or soil conditions. In this study a large set of ground motion records is simulated within a parametric exercise to investigat...
