In seismic design, beam yielding mechanism has been recommended and recently, performance based design is proposed. Performance of frame structure with weak-beam should be controlled by the estimated damages and supposed earthquake. In past study, the authors had showed the method to ensure a weak-beam mechanism for regular and symmetrical frame structure. This paper deals with the design procedure for weak-beam type structure, where both the problem and validity of the method are shown. The problem is how to specify the column strength distribution, though the methods of deciding a requisite strength and a beam strength distribution are valid. Multispan frame structure (MFS) with uniaxial spring model is used in the analysis. The above problem still exists in MFS while the decision method for first floor column and beam strength distribution are valid.
