This paper illustrates parameter optimization of compressive strength of steel fiber reinforced high strength concrete (SFRHSC) by statistical design and analysis of experiments. Among several factors affecting the compressive strength, five parameters that maximize all of the responses have been chosen as the most important ones as age of testing, binder type, binder amount, curing type and steel fiber volume fraction. Taguchi analysis techniques have been used to evaluate L-27 (3(13)) Taguchi's orthogonal array experimental design results. Signal to noise ratio transformation and ANOVA have been applied to the results of experiments in Taguchi analysis. The confirmation runs were conducted for the optimal parameter level combination, which is obtained from the results of the above methodologies. The maximum compressive strength has been observed as around 124 MPa. By using the optimal parameter level combination, the direct tensile strength and flexural strength tests have been conducted. The mean values at the age of 28 days are obtained as 7.5 MPa and 13 MPa respectively. In this study, it is clearly demonstrated that all main factors except steel fiber significantly contribute to the compressive strength of steel fiber reinforced high strength concrete, yet age and binder type are the most significant contributors.

Lateral stiffness of steel plate shear wall systems Topkaya, Cem (Elsevier BV, 2009-08-01) The accuracy of the finite element method and strip method of analysis for calculating the lateral stiffness of steel plate shear wall (SPSW) systems is assessed by making comparisons with experimental findings. Comparisons revealed that while both methods provide acceptable accuracy, they also require the generation of sophisticated computer models. In this paper, two alternative methods are developed. The first one is an approximate hand method based on the deep beam theory. The classical deep beam theory...
Nonlinear analysis of R/C low-rise shear walls Mansour, Mohamad Y.; Dicleli, Murat; Lee, Jung Yoon (SAGE Publications, 2004-08-01) An analysis method for predicting the response of low-rise shear walls under both monotonic and cyclic loading is presented in this paper. The proposed analysis method is based on the softened truss model theory but utilizes newly proposed cyclic constitutive relationships for concrete and steel bars obtained from cyclic shear testing. The successfulness of the analysis method, when combined with new materials constitutive relationships, is checked against the test results of 33 low-rise shear walls reporte...
Analytical prediction of thermal displacement capacity of integral bridges built on sand Dicleli, Murat (SAGE Publications, 2005-02-01) In this research, analytical equations are developed to calculate the lateral displacement capacity and maximum length limits of integral bridges built on sand based on the low-cycle fatigue performance of the piles under cyclic thermal variations and the ultimate strength of the abutment under positive thermal variations. To formulate the displacement capacity and maximum length limits of integral bridges based on the low cycle fatigue performance of steel H-piles under cyclic thermal variations, first, H-...
FINITE-ELEMENT ANALYSIS OF PRESTRESSED AND REINFORCED-CONCRETE STRUCTURES ELMEZAINI, N; CITIPITIOGLU, E (American Society of Civil Engineers (ASCE), 1991-10-01) A practical and powerful technique for the discrete representation of reinforcement in finite element analysis of prestressed and reinforced concrete structures is presented. Isoparametric quadratic and cubic finite elements with movable nodes are developed utilizing a correction technique for mapping distortion. Reinforcing bars and/or prestressing tendons are modeled independently of the concrete mesh. Perfect or no bond as well as any bond-slip model can easily be represented. The procedure is succes...
Effective flexural rigidities for ordinary reinforced concrete columns and beams AVŞAR, ÖZGÜR; BAYHAN, BEYHAN; Yakut, Ahmet (Wiley, 2014-04-25) Current effective flexural rigidities proposed for use in design and analyses of reinforced concrete structures have been examined. The level of accuracy in the estimation of section rigidity plays a very important role in determining realistic values for the structural stiffness and hence the seismic forces imposed. The most significant parameters influencing the effective rigidity, which reflects the effect of cracking as well as the theoretical yielding of reinforced concrete sections, have been determin...
