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.
