A computer program for the analysis of reinforced concrete frames with cracked beam elements
Tanrikulu, A. Kamil,Dundar, Cengiz,Cagatay, Ismail H. Techno-Press 2000 Structural Engineering and Mechanics, An Int'l Jou Vol.10 No.5
An iterative procedure for the analysis of reinforced concrete frames with beams in cracked state is presented. ACI and CEB model equations are used for the effective moment of inertia of the cracked members. In the analysis, shear deformations are taken into account and reduced shear stiffness is considered by using effective shear modulus models available in the literature. Based on the aforementioned procedure, a computer program has been developed. The results of the computer program have been compared with the experimental results available in the literature and found to be in good agreement. Finally, a parametric study is carried out on a two story reinforced concrete frame.
The use of discontinuous first and second-order mixed boundary elements for 2D elastostatics
M.H. Severcan,A.K. Tanrikulu,A.H. Tanrikulu,I.O. Deneme 국제구조공학회 2010 Structural Engineering and Mechanics, An Int'l Jou Vol.34 No.6
In classical higher-order discontinuous boundary element formulation for two-dimensional elastostatics, interpolation functions for different boundary variables (i.e., boundary displacements and tractions) are assumed to be the same. However, there is a derivational relationship between these variables. This paper presents a boundary element formulation, called Mixed Boundary Element Formulation, for two dimensional elastostatic problems in which above mentioned relationship is taking into account. The formulations are performed by using discontinuous first and second-order mixed boundary elements. Based on the formulations presented in this study, two computer softwares are developed and verified through some example problems. The results show that the present formulation is credible.
