The project management usually results in putting the civil engineering project into operation but while respecting the knowledge in the importance of operating costs for total effectiveness of the project during its life cycle, the project management should be extended over the complete life cycle of the building (including critical nodal points in exploitation of building).
In the course of designing and considering a future investment, the architect and the other participants to civil engineering project view the future facility with an eye of cheap acquisition costs from which they will get maximum benefits during exploitation, but the contrary is the case.
In the first phases of life cycle as well as in the civil engineering project, a lot of decision making take place, refer to Fig. 1, in which ideas of the investor about the properties and parameters of the facility are formed and it is indirectly decided on future operation and exploitation of the designed facility.
It incorporates the principles of business administration, architecture, humanities and engineering.
Newly emerging BIM philosophy in designing constructions contribute to discovering collision situations in the project stage of the civil engineering project in advance, e.g. between the supporting system and utilities, but these systems are not smart enough to be able to substitute the man – facility manager.

Key Words: reinforced concrete, temperature action, expansion and contraction joint distance
Abstract: A nonlinear program analyzing reinforced concrete frame and bent structures under
temperature action is developed and improved.
However abnormal phenomenon often appears in engineering practice.
Otherwise more and more engineers appeal to cancel joint distance.
In engineering practice[3][4], some methods ignore the action of temperature, in some instance, it leads to excessive expansion of temperature crack and excessive adding of structure distortion and as a result affecting structures' using and wear; some don't have reasonable reinforcing criterion; and others over estimate temperature effect, so have to reinforce too much and thus the methods are paradoxical with fact and experience.
Above all, the changing extent of internal forces of story increase of multi-storied is smaller than height increase of one-storied. 3.3Temperature Action Analysis As to one-storied, multi-storied frame and bent structures under uniform, linear and nonlinear temperature and their combination, temperature internal force difference rule are drawn in literature[1]. 4.Example of Practical Engineering Temperature action should be considered when super-length frame or bent structures' temperature joint distance is forbidden according to requirement.
