In this paper, a thermocouple psychrometric technique is used to measure soil suction and assess the reliability of a swell pressure prediction method. Kaolinite-bentonite clay mixtures were prepared to obtain expansive soils with a wide range of plasticities. Suction measurements using thermocouple psychrometers and constant volume swell tests in oedometers were made on statically compacted :specimens. Soil suction-water content relationships were evaluated. The results indicate a linear relationship between the logarithm of initial soil suction and swell pressure measured in the oedometer. it has been shown that the method proposed by Johnson & Snethen for the prediction of swell pressure using suction measurements overestimates the ultimate swell pressure.

Evaluation of displacement coefficient method for seismically retrofitted buildings with various ductility capacities Dicleli, Murat (Wiley, 2014-07-25) This research study is aimed at evaluating the accuracy of the displacement coefficient method (DCM) of FEMA 440 and associated nonlinear static procedure (NLSP) for actual buildings with soft story mechanism and various ductility capacities. The DCM and associated NLSP are evaluated using two existing seismically vulnerable buildings with soft story mechanism. The buildings are first retrofitted using a ductile steel-brace-link system to represent those with good ductility capacity and then retrofitted wit...
An improvement to linear-elastic procedures for seismic performance assessment Gunay, Mehmet Selim; Sucuoğlu, Haluk (Wiley, 2010-07-10) An improved linear-elastic analysis procedure is developed in this paper as a simple approximate method for displacement-based seismic assessment of the existing buildings. The procedure is mainly based on reducing the stiffness of structural members that are expected to respond in the inelastic range in a single global iteration step. Modal spectral displacement demands are determined from the equal displacement rule. Response predictions obtained from the proposed procedure are evaluated comparatively by ...
Comparison of 2D versus 3D modeling approaches for the analysis of the concrete faced rock-fill Cokal Dam Arıcı, Yalın (Wiley, 2013-12-01) This paper's primary purpose is to compare the 2D and 3D analysis methodologies in investigating the performance of a concrete faced rock-fill dams under dynamic loading conditions. The state of stress on the face plate was obtained in both cases using a total strain based crack model to predict the spreading of cracks on the plate and the corresponding crack widths. Results of the 2D and 3D analyses agree well. Although significantly more demanding, 3D analyses have the advantage of predicting the followin...
PREDICTION OF SEISMIC ENERGY-DISSIPATION IN SDOF SYSTEMS NURTUG, A; Sucuoğlu, Haluk (Wiley, 1995-09-01) A simple analytical procedure is developed for calculating the seismic energy dissipated by a linear SDOF system under an earthquake ground excitation. The ground excitation is specified by its pseudo-velocity spectra and effective duration whereas the SDOF system is defined by its natural period of vibration and viscous damping ratio. However, the derived relationship for the energy dissipation demand under an earthquake excitation is sensitive neither to the viscous damping ratio nor the ductility ratio w...
Effect of near-fault ground motion and damper characteristics on the seismic performance of chevron braced steel frames Dicleli, Murat (Wiley, 2007-06-01) This study is aimed at comparing the seismic performance of steel chevron braced frames (CBFs) with and without fluid viscous dampers (FVDs) as a function of the characteristics of the near-fault (NF) ground motion and FVD parameters. For this purpose, comparative nonlinear time history (NLTH) analyses of single and multiple storey CBFs with and without FVDs are conducted using NF ground motions with various velocity pulse periods scaled to have small, moderate and large intensities. Additionally, NLTH anal...
