The purpose of this study is to establish a rational aseismic design method, by means of experimental, and analytical research, applicable to the large turbine building of a thermal power plant, which accomodates many important equipment like steam turbines and generators, and incorporates aseismic elements composed of K-type braced frame. An elastic-plastic analysis was performed on the hysteretic behavior of K-type braced frames subjected to repeated horizontal load. The hysteretic behavior is largely influenced by the elastic-plastic behavior of the upper beam, because the brace is unable to hold it's full strength when the beam yield in bending by the vertical force caused by the braces unbalanced force. Parametric studies were conducted taking notice of elastic-plastic interaction behavior between the upper beam and braces to develop the design indicator of beams and braces and also to propose the ultimate strength formula for K-type braced frame. The analysis results are summerized as follows. * Interaction effects largely concerned with the hysteretic behavior were clarified by easy design indicator formula. * The hysteretic property of the system depends much on the upper beam performance such as moment of inertia and plastic moment. * The ultimate strength formula is derived herein using the design indicator. * A force restoring characteristic and the ultimate strength are easily controlled by only the upper beam performance, hence, rational aseismic design procedures are easily conducted using the proposed design indicator.
