The paper presents an extensive study aimed to determine the applicability of demountable Bailey bridge (BB) system on construction sites or in other temporary conditions while meeting regulations for design and assessment steel bridges. analysis is focused whether what extent BB with spans between 12 36 m usable on-site freight transport conventional lorries a total weight up 22–28 tons. At sa...

the effect of steel plate thickness on the repair effectiveness of rc beam is presented in this paper. a total of four beams were tested, one beam repaired by cfrp with a thickness of 1.2 mm and used as a control beam, and three beams repaired by a steel plate. steel plates with a thickness of 2 mm, 3 mm, and 4 mm were used in repairing the beams. the maximum load-carrying capacity, deflection ...

A simple model of a raft made of spaced nano-cylinders is formulated and discussed, in order to improve the understanding of load-carrying capacity of insects and miniature devices that float on liquids. It is shown that mostly the outer cylinders of the raft determine the load-carrying capacity. Therefore, the raft porosity (spacing of the cylinders) is instrumental mainly in increasing the lo...

The stability analysis of sleeve stiffened pin-ended slender hollow columns of pipe or box section is performed in the present study. This is accomplished by using energy method, employing three terms in the assumed approximate deflection function. The lengthy and tedious algebraic manipulations involved in solving the relevant eigenvalue problem, necessitates employing the "MATHEMATICA" softwa...
