【Abstract】 Two types of floor plate structure were designed for a same multi storey building:ordinary slab beam structure and hollow cored flat plate structure. The later as a new technique was adopted in order to save the consumption of concrete and reinforcement. Two types of plate structure’s consumption of materials are calculated and it is found out that the hollow cored flat plate is not more economical than the slab beam as expected.Analysis is made and for the improvement and further application of hollow cored flat plate structure,some suggestions are proposed.更多还原
