EARTHQUAKE RESISTING DESIGN METHOD ON THE BASIS OF PC BINDING ARTICULATION CONSTRUCTION METHOD

摘要

In an earthquake resisting design method for a prestressed (PC) structure, columns and beams as high-strength precasted and prestressed concrete members are bonded by PC steel materials and then grout is charged for attachment. In case of earthquakes having a predetermined earthquake load design value, a first-stage linear elastic design is applied to prevent damage to all the structural members. In case of earthquakes over the predetermined earthquake load design value, a second-stage linear elastic design is applied to absorb earthquake energy by breaking the attachment of the grout and to prevent damage to major structure members. The present invention is formed of a nonlinear elastic design wherein the first-stage linear elastic design and the second-stage linear elastic design are combined to drastically increase a seismic design level and to endure a very strong earthquake of six degrees intensity.
