To shorten calculating time on settlement of structure, new equations that calculates only the ultimate settlements are introduced. And new equations are used, to examines the factors that influences settlements of structure. Main conclusions are as follows. 1. The influences of piles on settlements of structure are to be decrease both differential settlements and bending moments. 2. By increase the bending rigidity of structures, the differential settlements are decrease but bending moments are increase. 3. The maximum inclination of structures is proportional to the maximum settlement of structures, but the proportional relation between the maximum inclination of structures is uncertain.
