Free Vibration Analysis of Repetitive Structures using Decomposition, and Divide-Conquer Methods L Shahryari This paper consists of three sections. In the first section an efficient method is used for decomposition of the canonical matrices associated with repetitive structures. to this end, cylindrical coordinate system, as well as a special numbering scheme were employed. In the second section, divide and conquer method have been used for eigensolution of these structures, where the matrices are in the block tri-diagonal form. In the third section a comparison of the results is presented. In order to illustrate the efficiency of the aforementioned methods, repetitive structures are considered in the form of barrel vault space structures. منبع دانلود JSEG201348691400.pdf

Investigating the Distribution and Orientation of Steel Fiber Reinforced Concrete Original Article, B34 Zandi Y. Journal. Civil Eng. Urban. 2(5): 191-195. 2012. ABSTRACT:The distribution functions of fiber location variables were investigated that can be used to produce an analytic model to predict the mechanical properties of SFRC. Considering the effect of surrounding boundaries and distribution function, theoretical expressions were derived for the number of fibers per unit cross sectional area in SFRC. A comparison between empirical results and the theory were done to confirm the analytical results. Fibers are usually used in concrete to control cracking due to both plastic shrinkage and drying shrinkage. The amount of fibers added to a concrete mix is expressed as a percentage of the total volume of the composite (concrete and fibers), termed volume fraction (Vf). Vf typically ranges from 0.1 to 3%. Fibers with a non-circular cross section use an equivalent diameter for the calculation of aspect ratio. Keywords:steel fiber reinforced concrete; steel fibers; vibration, distribution function. منبع: [Hidden Content] دانلود: [Hidden Content],%20B%2034%20191-195.pdf JCEU, B 34 191-195.pdf
