Fatih mosque, a landmark structure in Istanbul, has suffered structural damage during 1999 Kocaeli earthquake. Using spectral, time-domain (OKID/ERA for SISO and MIMO models) and T-F domain ( WT, HHT ) techniques on ambient vibrations, damage identification has been performed. Results of parametric and spectral analyses indicate close global peaks. Northwest arch ( O 3 ) that was expected to move in harmony with other arches cannot display such a consistent behavior and produces additional local frequency at 24Hz due to disintegrated stones around the crown. Southeast arch ( O 1 ) also has comparable damage producing another locality at 38Hz. Extending linear approaches into nonl inear-nonstationary methods, WT and HHT improved the results in the temporal-frequency energy distribution. Estimated individual and global structural behavior are consistent with visually inspected damage states for O 3 and O 1 . On a global scale, damage additionally generates significant nonstationarity. D ecompositions in WT and HHT show the capability of identifying nonlinear-nonstationary process hidden in the data. T-F analysis detects and localizes any anomalous system behavior and can adequately capture the dynamical behavior of damage in any instrumented part of the structure at any particular time epoch. For historical masonry structures with vulnerable components like large central dome and arches that have low redundancy, there is a need to develop automatic signal/image processing through image processing, machine vision, and pattern recognition for early diagnosis and prognosis for warning of gradually emerging structural degradations.

The present study investigated the corrosion behavior of reinforcement bars embedded in alkali-activated (ARPC) and conventional (CRPC) reactive powder concretes. Corrosion progress in 3.5% NaCl solution, water and air environments were monitored up to 365 days. The physical and mechanical characteristics, such as water absorption, rapid chloride ion permeability, compressive and flexural strength, and corrosion characteristics, such as half cell potential and corrosion current intensity results were compared for ARPC and CRPC matrices. Even for the same mechanical performance, alkali-activated mortars were found to have a high permeable structure and an early depassivation of the rebars occurred. In the propagation stage of chloride induced corrosion, almost 13 times higher corrosion current intensity values were measured as well as earlier deterioration and cracking was observed for ARPC compared to CRPC.

Seismic performance evaluation of non-seismically detailed reinforced concrete buildings requires proper analytical modeling approaches for beam-column joints which are most vulnerable parts. This study investigates the influence of beam column joint modeling assumptions on performance evaluation of non-ductile RC buildings. Numerical simulation model includes truss-based elements for beam-column connections and fiber-based elements for beams and columns. Two-dimensional four- and six- story reinforced concrete frames of an existing RC building are designed and analyzed by conducting incremental dynamic analyses. Column chord rotations and corresponding strains are compared with code provisions for performance assessment of non-ductile RC frames.

This research discusses the chloride diffusivity of concrete as well as corrosion performance of rebars in cracked and uncracked states. Prismatic concrete specimens with two water-to-cement ratios, two concrete cover thicknesses with and without steel fibers were used. Three-point flexural loading was applied to form cracks and cracks were sustained by a bolt system. Half-cell potential and corrosion rate measurements were carried out following wetting – drying cycles in chloride environment which were continued for 80 weeks. The positive effects of lower water – to – cement ratio and greater cover depth were found to be surpassed by existence of cracks in concrete.

Lightweight cellular hollow concrete (LCHC) block is a type of masonry unit manufactured by precast technique. LCHC block is produced by the mixing of Portland cement, volcanic tuff powder, expanded clay aggregate and diatomite for building applications. LCHC blocks are lightweight and being frequent cellular hollow cleavages, give excellent thermal and acoustic performance, fire resistance and high weathering resistance to the buildings. In this research work, LCHC blocks with 28 different mixture batches were cast into a mould with vibro-compacting, de-moulded immediately and transferred to a storage area for curing up to 120 days in normal air condition. Totally 21 cellular space with 10 mm in width were placed in the block design. For each mixture, twenty four block samples were prepared and tested in the air dry condition for compressive strength and water absorption in accordance with BS 1881: Part 116. This paper initially examines how volcanic tuff powder affect the characteristics of lightweight concrete masonry mixtures and also investigates the use of quartet blends containing volcanic tuff powder, expanded clay aggregate, diatomite and cement to produce LCHC blocks for walls and partitions.

This study investigates the flexural behavior of Ultra-High Performance Fiber Reinforced Concrete (UHPFRC) with hybrid steel fiber referencing the ASTM standard C 1609. Two types of end-hooked fibers in macro fiber concretes and one type short straight fiber in micro fiber concretes were used in mono and hybrid forms. In order to determine the flexural response of UHPFRC, a series of prismatic beam specimens with a dimension of 100 x 100 x 400 mm were tested under the four-point loading and following parameters were compared and discussed in terms of the first cracking load and pattern, flexural strength, deflection capacity, toughness and residual strength capacity under bending loads. The test results showed that as the fiber amount of specimens with the mono fiber increases, in general, better flexural behavior may be ensured. It should be also noted that the hybrid use enhanced the flexural behavior compared to the macro fiber usage.

Economic growth and the increase in the population trigger consumption and increase the amount of waste produced. One of the resulting wastes is glass and using of these large amount of glass waste materials by environmental methods is seen as an important issue. On the other hand, there are difficulties due to the decrease of natural resources in the supply of aggregates used in asphalt pavements. In this study, the use of waste glass instead of natural aggregates in asphalt pavements was investigated in terms of water damage. In addition to base bitumen, hydrated lime modified and SBS modified bitumen were used in experimental studies. The waste glass was added in two different sizes (as filler materials and 2 mm sized fine aggregate) and three addition ratios (20%, 30% and 40%) instead of basalt aggregates. The asphalt mix samples produced in optimum bitumen contents were evaluated for water damage by AASHTO T 283 method. Asphalt mixture with 20% glass filler showed the highest water damage resistance. Among the options where the glass aggregate size was chosen as 2 mm, the highest water damage resistance was realized at addition rate of 30%. Both hydrated lime and SBS polymer were effective in improving water damage resistance. However, the highest tensile strength ratio was obtained with hydrated lime. The optimum bitumen contents of the mixtures with glass aggregates produced with both base and modified bitumen were decreased compared to that produced entirely with basalt aggregate. According to the test results, it is understood that the filler materials produced from waste glasses can be used instead of natural aggregate filler.

A total of five specimens were designed to investigate the cyclic behavior of infill panels made from various materials such as thin-walled steel sheets and corrugated sandwich panels. First, two specimens were prepared to act as shear walls by connecting sandwich panels, which are normally used as architectural partition walls in steel buildings, to a steel frame using appropriate connections. Then, a specimen with a single steel plate was designed. The final specimen was prepared by removing the polyurethane material from inside the sandwich panel and only steel plates were attached to both faces of the frame. This way, it was possible to examine the effect of the polyurethane material inside the sandwich panel and the corrugated steel plate on system behavior. Finally, a bare frame was prepared as a control specimen. For this experimental study, single-story, single-bay steel frames of semi-rigid beam to column connections were prepared with a scale ratio of 1:3. In all specimens, the infill plates were fastened to the frame connection profiles using self-drilling screws and the prepared specimens were compared in terms of their maximum load capacity, initial stiffness, ductility and energy dissipation capacity values under cyclic loading. The experimental and analytical investigations showed that, like steel plate infills, the specimens with sandwich panels also behaved in a ductile manner with relatively lower load and energy dissipation capacity. The results of the computer model analyses were then compared with the experimental results and they were found to be compatible with the analytical results.
