Effect of Near-Field Ground Motion and Isolator Properties on the Performance of Seismic-Isolated Bridges



Effect of isolator and ground motion characteristics on the performance of seismic-isolated bridges
Dicleli, Murat (Wiley, 2006-02-01)
This paper presents the effect of isolator and substructure properties as well as the frequency characteristics and intensity of the ground motion on the performance of seismic-isolated bridges (SIBs) and examines some critical design clauses in the AASHTO Guide Specification for Seismic Isolation Design. For this purpose, a parametric study, involving more than 800 non-linear time history analyses of simplified structural models representative of typical SIBs, is conducted. The results from the parametric ...
Effect of vehicular and seismic loads on the performance of integral bridges
Erhan, Semih; Dicleli, Murat; Department of Engineering Sciences (2011)
Integral bridges (IBs) are defined as a class of rigid frame bridges with a single row of piles at the abutments cast monolithically with the superstructure. In the last decade, IBs have become very popular in North America and Europe as they provide many economical and functional advantages. However, standard design methods for IBs have not been established yet. Therefore, most bridge engineers depend on the knowledge acquired from performance of previously constructed IBs and the design codes developed fo...
Effect of cold rolling and annealing parameters on the microstructure and mechanical properties of dual phase steels
Poyraz, Okan; Ögel, Bilgehan; Department of Metallurgical and Materials Engineering (2020)
This study consists of change in the microstructure and mechanical properties of the 0.14C-1.98Mn steel with different cold rolling ratios, annealing temperature and annealing time. The starting sheet metal is 2.8mm thick and have a microstructure of ferrite-pearlite in as-received condition. Samples are cold rolled such that either 30%, 45% or 60% cold rolling is achieved. In order to see the change in microstructure below and in the intercritical temperatures, samples are annealed for 5 minutes or 10 minu...

Effect of Laser Parameters and Post-Texturing Treatments on the Optical and Electrical Properties of Laser Textured c-Si Wafers
RADFAR, Behrad; ES, FIRAT; NASSER, Hisham; AKDEMİR, Ozan; Bek, Alpan; Turan, Raşit (2018-03-21)
Surface plays a crucial role in the performance of crystalline silicon (cSi) based solar cells as it affects both electrical and optical properties. To minimize reflection from the flat surface and thus improve light trapping, the cSi wafers must be textured. For mono-cSi cells, anisotropic alkaline etchants are commonly utilized to create pyramids on the surface. However, this method is not viable for multi-crystalline silicon (mc-Si) wafers due to the presence of different and random crystallographic orie...
