Abstract:
In an earthquake resisting design method of a PC construction, a column and a beam, which are high-strength precast prestress concrete members, are joined by binding juncture with a prestressing tendon. A grout is filled and bonded. A first stage linear resilient design is employed, where all construction members are not damaged, for earthquakes up to a predetermined earthquake load design value. A second stage linear resilient design is employed, where earthquake energy is absorbed by breakage of the bond of the grout, and principal construction members are not damaged, for earthquakes exceeding the predetermined earthquake load design value. By employing a non-linear resilient design in which the first stage linear resilient design and the second stage linear resilient design are combined, an earthquake-resisting design level is significantly increased, and the construction can resist earthquakes exceeding a seismic intensity 6 upper.
