Abstract
(1) We found that the acculately compated pannel's shear deformation and yield point by stress function and those by simplified Equation (20) are almost the same. Both of them coinside with the test results well. (2) When the amplitude of the reciprocal load over yield load is increased, the rigidity of the pannel decrease. As it is very complicated and diffecult to apply this reduction of pannel rigidity to the connection behavior, it is desirable to keep the pannel zone within elastic zone. (3) Even if the panuel zone remains in the elastic zone, the horizontal deflection of the rahmen construction due to the pannel shear deflection is considerably large. Because, in the case of high rise buildings of which construction design is restricted by the horizontal deflection, this additional deflection can not be ignored.
