| Abstract |
The curtain wall construction applied on high-rise building facades in Korea became generalized, but specialty of the CMr(Construction Manager) who needs to perform economical project management with specialty in the curtain wall construction is still lacking. Therefore, this study performed about the business management plan of the design and construction phase for profitability provision of the curtain wall construction. This study analyzed the structure design standard of the curtain wall, researched economical design alternatives, and analyzed the Mock-up test of 16 curtain wall projects that were recently conducted. Based on the research results, this study suggested items to be confirmed at the time of inspecting the structural design by curtain wall system, improvement method of the section properties for economical efficiency of sections, and ways to improve the distance between anchor point and sleeve or stack joint. Also, this study classified causative factors of the difference in the curtain wall mock-up test deflection value and the design deflection value into, 1)problem in the member connections, 2)problem in manufacturing the structure, 3)problem in the structure analysis and 4)problem of assumptions at the time of designing the structure, and suggested a project management strategy for CMr to secure economic feasibility and quality of the curtain wall. |
