Abstract
In this paper, I report the settlement ratio of structures (observed retative settlement/computed relative settlement). The results are as follows. 1. The practical equations of the settlement ratio of structures are reported in this paper. 2. The observation results and theoretical results by model structures are generally in fair agreement. 3. The settlement ratio of structures are much influenced by the number of storys, the slenderness of members, the settlement value of structures and the rigidity of concrete walls.
