The characteristics of effect are expounded for different structure under the specific load. These internal force and deformation characteristics in conceptual design should be caused take attention seriously. After summing up a lot of engineering structure calculation based on the results of different structure, some typical characteristics of load effect can be reduced , usually these typical effects called conceptual design features. Understanding of these internal force and deformation characteristics of structures is beneficial for deepening professional quality, and improving the professional foundation. Readers with diligence paid to various structure and further study, will be able to cognitively find more conceptual design features, make innovations, and constantly enrich itself the experience of conceptual design.
