Abstract

Abstract

A comparative experiment on the externally prestressed simple beams and frame beams is conducted. Through this experiment, the theory is proved that shearing force of frame columns is enhanced and effective prestressing of horizontal members is decreased because of effective lateral restraint of the frame columns. And the suggestions are proposed that secondary axial force in frame and shear wall structure must be considered and that of how to increase shearing capacity of frame columns.
