Technical-and-economic efficiency of reinforced wooden structures

摘要

The article is devoted to the investigation of the technical and economic efficiency of the reinforced wooden structures by the example of the load beams with a span of 18 m.The efficiency has been estimated by the constructional,technical and economic indexes such as the relative height,relative installation weight and relative unit cost.All indexes have been considered in comparison to the equally efficient and equally rigid reinforced and unreinforced wooden structures.Technical and economic indexes of the beams have been given:the bulk,consumption of basic materials,labor intensity,factory price,total value,capital investments and reduced costs.The efficiency of using group reinforcement over a part of the beam length compression area has been substantiated.
