Beams and Column's Connected Forms of Unbonded Precast Concrete Frame Structure

With the advance of China's urbanization, the quantity and quality requirements for residential buildings are getting higher and higher, the housing industry is an important way to promote China's urbanization. The prefabricated concrete structures of the technical development and promotion is an important means to achieve housing industry. And to research a reasonable form of beam-column connection is the top priority of the prefabricated concrete structures research and promotion. This paper summarizes the recent year's domestic unbonded post-tensioned prefabricated concrete frame structure beam-column connection form and seismic performance.
