Development of a Parametric Equation to Predict the Joint Shear Strength

This paper presents an analytical study that focuses on the development ofa parametric equation to predict the joint shear strength. In this analytical study, adatabase containing geometric properties, material strengths, configuration detailsand test results of reinforced concrete beam-to-column connection subassembliestested under cyclic loading is established. Then, based on the experimental results,parameters affecting joint shear capacity are determined. The most influentialparameters are selected and an equation to predict the maximum joint shearstrength is formed. The developed equation includes parameters that take intoaccount the effect of eccentricity, wide beams, transverse beams and presence ofslab on the seismic behavior of the connection region, besides the key parameterssuch as concrete compressive strength, effective joint width and joint transversereinforcement ratio. The maximum joint shear strength vales obtained by theproposed equation are then compared with different code approaches and thecomparison results are discussed.


Development of an elasto-plastic analytical model for design of grouted rock bolts in tunnels with particular reference to poor rock masses
Osgoui, Reza Rangsaz; Karpuz, Celal; Department of Mining Engineering (2007)
The analysis presented in this thesis provides a methodology for grouted bolts design, based on empirical and analytical methods. Hence, the main objectives of this thesis are to offer practical means for better characterisation of poor to very poor rock masses, to better predict support pressure, and to develop an elasto-plastic analytical model for design of grouted bolts in tunnels excavated in such rock masses. To improve the applicability of the GSI (Geological Strength Index) in poor to very poor rock...

This paper describes formulation of a hand method which can be used to estimate the computed fundamental periods of vibration of steel eccentrically braced frames (EBFs). The developed method uses the Rayleigh's method as a basis and utilizes the roof drift ratio under seismic forces as a parameter. The roof drift ratio was obtained from EBF designs by considering different seismic hazard, number of stories, braced bay width, and link length to bay width ratio. A simple expression was developed to represent...
Development of a fast analytical method for prediction of part dynamics in machining stability analysis
Alan, Salih; Özgüven, Hasan Nevzat; Department of Mechanical Engineering (2009)
The objective of this study is to develop and implement practical and accurate methods for prediction of the workpiece dynamics during a complete machining cycle of the workpiece, so that FRFs of the workpiece can be used in chatter stability analysis. For this purpose, a structural modification method is used since it is an efficient tool for updating FRFs due to structural modifications. The removed mass is considered as a structural modification to the finished workpiece in order to determine the FRFs at...
Development of a pressure-based solver for both incompressible and compressible flows
Denk, Kerem; Sert, Cüneyt; Department of Mechanical Engineering (2007)
The aim of this study is to develop a two-dimensional pressure-based Navier-Stokes solver for incompressible/compressible flows. Main variables are Cartesian velocity components, pressure and temperature while density is linked to pressure via equation of state. Modified SIMPLE algorithm is used to achieve pressure-velocity coupling. Finite Volume discretisation is performed on non-orthogonal and boundary-fitted grids. Collocated variable arrangement is preferred because of its advantage on staggered arrang...
A method of strain and stress analysis for failure prediction in laminated composites
Ardiç, E.S.; Bolcan, C.; Kayran, Altan (SAGE Publications, 1995-01-01)
In this study, a method of strain and stress analysis is developed to predict the failure initiation in laminated composites containing two or more different kinds of laminae. In principle, the method developed in this study is similar to non-local elasticity, but the long-range interactions are considered on the strains instead of material moduli, and the method is developed and applied as a realistic and practical one. Firstly, the strain fields in each layer are determined separately and then these strai...
