Abstract
Comparative analysis of the efficiency of the use of caisson Skydome in modern multistory buildings with the standard columns step
Incoming article date: 14.12.2016The market in Russia is common formwork caisson ceilings SkyDome system.In the article the question of the effectiveness of ribbed caisson ceilings in multi-storey monolithic buildings compared to with .flat slab floor. The program complex "Lira-CAD 2013" calculated the 18-storey residential buildings with monolithic framework. Consider in detail the reinforcement floors typical floor in two versions: a flat of 200 mm and a caisson plate of 50 mm and beams with a section of 200х350 mm with a step of 900х900 mm. Analysis of the results showed that in a building with columns a step of about 5 m difference in cost of materials for the manufacture of the overlap was about 1%. Efficiency gains are expected by increasing the span up to 8 ... 10 m
