for high-rise reinforced concrete frame buildings subjected to earthquakes
Kazushi SHIMAZAKI and Akira WADA
Summary
This paper proposes a design method oriented to the displacement
response for high-rise reinforced concrete frame buildings subjected to
earthquakes. First, the equivalent shear stiffness distribution of high
rise RC buildings are investigated considering bending and shear
deformation. The equivalent shear stiffness distribution recommended
is linear to hyperbolic normalized distribution of 0.1〜0.20 at the
top depending on the share of bending and shear deformation.
Using these results, the outline of a design method
is proposed. The applications of this method to 25 and 60
story buildings are showed. In-story displacement responses
during severe earthquakes are estimated and examined. The results
satisfied the design criteria.
