Analysis of Reasonable Height and Span for Column-Slab Residential Buildings Assembled

Slab-column structure assembled by monolithic prestressing is a type of structure system in which prefabricated reinforced concrete slabs and columns are main members bearing load.The structure feature and mechanical properties of slab-column structure assembled by monolithic prestressing are introduced.Considering the amount of structure concrete of a unit construction area as economic indicator and taking into account the popular residential building style,the reasonable height and span of column-slab residential building assembled by monolithic prestressing are theoretically analysized with the help of SATWE software.Results show that the height of 30.8 m is relatively reasonable when its span is 7.8 m and sectional dimension of the column is 600 mm×600 mm;the span of 9.0 m is relatively reasonable when its height is 44.8 m and sectional dimension of the column is 800 mm×800 mm.
