The combined overlappings for buildings of frame constructive system with the increased grid of columns
Designing of overlappings in buildings of frame constructive system with the increased grid of columns, is interfaced to a number of problems. Implementation of all requirements at design of overlappings of such buildings involves the increased overlapping thickness, and as a result increase in a total structural volume.One of the main objectives facing designers and architects – reduction of constructive height of overlapping.Application of the combined overlappings is the best opportunity for reduction of a total structural volume of the building. However not all the combined combined ferroconcrete plates of overlapping meet these requirements. Calculations show that a combination of flat and cylindrical plates are characterized by decrease in a consumption of concrete by 23-74%, became for 41-81% in comparison with plane overlappings.
