PROBLEM TO BE SOLVED: To construct a high-strength and low-weight building.SOLUTION: A lightweight load resistant structure comprises an upper concrete part and a lower concrete part. The upper concrete part is formed from high-strength concrete on a top face of a lower concrete part (1), and the lower concrete part is formed from low-strength concrete. The top face of the lower concrete part has a plurality of positions defined as a plurality of higher positions and lower positions disposed between the higher positions, and the upper concrete part forms a compressed arc including a transverse section which increases from the higher positions to the lower positions, or preferably, is included in the roof or the like. |
