| Title of the article | Enhancement of frameless arch building by the system of chordates puffs |
| Abstract. | Construction of arched structures of thin-walled elements, produced by mobile units of rolled galvanized steel on the construction site is promising, reducing the cost of construction. In the manufacture of arched elements to make them curvature transverse corrugations are formed on their surface that significantly reduces their carrying capacity. In this regard, in order to prevent accidents must be reduced to 12 spans of 15 m. If necessary, the construction of buildings has to resort to their strengthening. In this paper we propose a new method for enhancing the arched structures by setting chord puffs. The design of a complex system gain, for calculating the use of special techniques. The authors present the method of amplification, a description of the analytical and numerical methods for calculating the gain realized in the program «ARHOR» and a concrete example of using this method for enhancing the arch structures span 30 m. According to the calculation results, it follows that increasing the number of puffs chord reduces the bending moments in the arch, but it increases the value of the longitudinal force and the maximum force in tightening. In the above case, the most rational chord delays is seven. |
