It is about a method.
Recently, with the seriousness of environmental problems, various technologies are being developed to reduce the amount of CO 2 generated in the construction industry, which is one of the environmentally harmful industries. These prior arts are focused on the development of new materials with low CO 2 emissions or the development of technologies for reducing the CO 2 emissions generated during the maintenance phase of buildings. However, in order to reduce CO 2 emissions more effectively in the construction industry, technology development should be carried out to reduce CO 2 emissions from the initial design stage for construction.
As a prior art, Korean Patent Application Publication No. 10-2011-0026351, "Total Life Cycle Cost Analysis System for Buildings," is an analysis period and interest rates for facilities constructed by private investment projects such as BTL (Build-Transfer-Lease). Based on the variable factors such as initial investment cost, operation management cost, maintenance cost, energy cost, and disposal disposal cost, the total lifecycle cost is analyzed roughly at the beginning of the project, and the building is verified for the feasibility of the project cost before the BTL project.

However, the related art is a conventional technology for minimizing CO 2 emissions and minimizing management costs in a building maintenance step such as operation management and maintenance of a building, and environmental considerations in a building design step are not considered. In addition, the related art does not take into account the environment generated in the material production step of the building before the construction or maintenance step. Therefore, the related art has a problem that it is not possible to reduce the cost and CO 2 emissions generated in the design phase of the building material (synthetic column).

In addition, in the present invention, only the embedded composite pillar (SRC) that is a vertical member of the building frame method. In the building frame system, the core shear wall bears more than 75% of the lateral force, so that the core bears all the lateral force and the moment frame bears only the gravity load. In the building frame method, the column bears only the gravity load, so the load of the column due to the change of the column cross-section performance in the optimized design method is the change of the self-weight, which is relatively smaller than the total gravity load the column bears. The load and the member force can be assumed to be constant. For this reason, the proposed method of designing the optimized columnar columns is a design method that can be applied to a high-rise building with a large number of members because it is not required to repeat the structural analysis.
