。Furthermore, prestressed concrete structures and steel structures are advantageous for relatively large span structures, but they are not effective in high-rise, large span structures because the beams and column cross sections become large. In addition, in the case of large-span prestressed concrete structures, tension steel members are placed on site.
Because the concrete was placed on-site, it was necessary to consider the order of concrete placement and the order of tensioning the tension steel.
