Purpose
In this research, a gene-scale design, self-diagnosis, and anti-aging technology will be developed in the form of a health care system for structural systems for buildings. The building health care technology through the fusion of genomics, IT, and structures will allow structural engineers to monitor the levels of safety and serviceability of a structural system at any time. From a distance they can examine the condition of structural members and connections, check functioning of individual parts, diagnose what actions are needed to fix the problem, and obtain optimal repairing solutions. Application of the technology to a building, the span of life will be lengthened in a systematic way. The technology will be applied to various structural systems consisting of steel, reinforced concrete, and composite members.

contents
In the proposed ᒥDevelopment of Gene-Scale Design, Self-Diagnosis, and Anti-Aging Technology for Structural Systems in Buildingsᒧ, member, support, connection, material properties and structural characteristics are expressed as gene and the combination of the genes which are those structural components is regarded as genome. Thus, a designed structure is expressed as one genome consisting of combination of a variety of genes. In this aspect, whole process from design to demolish for building structure include 1) selection of a optimum design among the multiple structural design alternatives, a group of genome, generated from multi-objective genetic algorithm in manufacturing phase of the building, 2) assessment of aging degree of gene in genome which means damage severity of the selected structure due to the external loads and 3) comparing initial condition of gene in the genome with damage assessment of gene and determining appropriate treatment or demolition. The structural analysis required in the manufacturing and assessment of deterioration for the building is based on the elastic and inelastic analysis method and the optimum design method considers member size, material characteristic, strength, stiffness, CO2 emission in design variable and objective function. To monitor deterioration of the structure in real-time, advanced structural monitoring technology and system identification method are developed using gage-free sensor network and vision-based 3D-motion capture system. In the system identification method, data parallel computing which is one of the efficient computational method is used to overcome the disadvantage of the existing techniques. The maintenance and retrofit techniques treating damaged structural components are developed based on the optimization methods considering cost and CO2 emission in the objective functions.

Development results
The development results of this research are summarized as follows. 1) The technology of elastic/inelastic multi-objective optimal design model was developed. To overcome the limitations of optimum design models for large-scale structures with iterative nonlinear analyses, a high-performance distributed optimal design model was developed. In the developed distributed model using a multi-core PC, the high-performance computing capability of a multiple PCs was efficiently utilized in the optimal design model. 2) The integrated structural health monitoring system for building structures which can measure structural responses and evaluate the changes in stiffness of the structure due to the aging of structures at both the member and building levels was developed as a new technology in an engineering field. The integrated monitoring system which can reasonably evaluate the safety of building structures subjected to earthquakes and wind loads was suggested. 3) The evaluation technique of structural damages at the member and building levels was developed in the form of a new visual SI and model updating method. Through various structural experiments including a shaking table experiment, the technology was verified and applied to actual skyscraper buildings.

The integrated monitoring system combined with the damage evaluation technology can be used on realistic applications and, in turn, the integrated monitoring systems can be used to guarantee the safety of citizens reasonably. 4) An ANN model, which can realize the safety/serviceability monitoring system for the structures which do not need the sustainable maintenance of sensors, was developed and it was verified through various experiments. This technology is the world's first new technology, called sustainable SHM, and it is evaluated as an innovative technology which can overcome the limitations of existing SHM. 5) The reasonable strength/stiffness retrofit technology of structures subjected to earthquakes and wind loads was developed in the form of multi-objective retrofit technique. In particular, in addition to the structural performance of retrofitted structures, the unique model can consider the CO2 emissions related the retrofit process.

Expected Contribution
Longevity of the building is expected through new concept and model established in the proposed research. It enables to increase the average lifespan of the building from 100years to 120years, reduce 20% of the domestic construction cost (100trillion won) and economic loss by CO2 emission (2trillion won) and bring economic effects of 21trillion for a year. For technical and social aspects, the proposed research will make a large contribution to enhancement of national competitiveness through 1) reorganizing the Korea architectural engineering into the high value engineering field, 2) creating the new demands and diversifying revenue by the development of new products, 3) extending to the adjacent industries and 4) training the talented individuals and leading technique in the relevant engineering field.
