This paper presents an evaluation on the minimum shear reinforcement requirements given in the ACI, Canadian, and Turkish codes for high-strength concrete. Thirteen beams having the minimum shear reinforcement required by ACI 318-83, the Turkish Code, and the equations proposed in this paper were tested Concrete strength varied between so and 80 MPa (8700 and 11,600 psi). For high-strength concrete (f(a)' > 69 MPa), the minimum shear reinforcement requirements of the Turkish Code and ACI 318-95 are not very different from one another Similarly, requirements of the 1994 Canadian Code (CSA A23.3-94) are not too different from the proposed equation. In light of the test results, the adequacy of code requirements are discussed. Emphasis is given to reserve strength ductility, and cracking.

Analytical modeling of fiber reinforced composite deep beams Yağmur, Eren; Burak Bakır, Burcu; Department of Civil Engineering (2018) Discrete fibers are often used as reinforcement to increase the tensile and shear strengths of concrete. For many years, the behavior of fiber reinforced composite members has been investigated both experimentally and analytically. The influence of fibers on the behavior of shear critical members is quite significant, therefore, it is inevitable to develop a method, which estimates the shear strength of fiber reinforced composite deep beams realistically. This is why one of the main objectives of this study...
Evaluation of tension lap splices for code provisions Canbay, Erdem (2012-09-01) Six real-size beams were tested in order to examine the reliability of tension lap splices for the minimum requirements of clear cover, spacing between bars and transverse reinforcement. The beams were prepared in accordance with the minimum provisions of the American Concrete Institute building code requirements for structural concrete (ACI 318-08) and the Turkish standards on requirements for design and construction of reinforced concrete structures (TS 500). Results showed that all beams prepared in acco...
Prediction of Elastic Moduli Development of Cement Mortars Using Early Age Measurements Deniz, Saygin; Erdoğan, Sinan Turhan (American Society of Civil Engineers (ASCE), 2015-01-01) This paper presents an investigation of the time development of dynamic and static elastic moduli of eight mortars made using CEM I cements with contrasting properties. Mixing and the preparation of dynamic testing prism specimens conformed to European standards. A nonstandard specimen and bending test setup was devised for measuring the development of a static Young's modulus. It was determined that dynamic Young's moduli determined using an ultrasonic pulse velocity test are often, but not always, greater...
Comparison of Two Alternative Silicon-On-Glass Microfabrication Processes for MEMS Inertial Sensors Torunbalci, M. M.; Tatar, E.; Alper, S. E.; Akın, Tayfun (2011-09-07) This paper presents experimental comparison of a modified silicon-on-glass (M-SOG) process to a previously-reported classical SOG (C-SOG) process based on the use of SOI wafers, yielding a stress free < 111 > silicon structural layer with desired structure thickness. The basic difference between these processes is the sequence of the step at which the silicon microstructures are defined by DRIE, making M-SOG more robust against critical dimension (CD) variations. Overall, M-SOG provides a simple, high yield...
