From the analysis, some suggestion about joint rigidity design is put forward : 1. joint initial rigidity can be enhanced within the limited range when to increase end - plate thickness ; 2. the rigidity and ultimate moment can be enhanced obviously when to adopt the beam with inclined section or to add axilla at the connections between beam and column ; 3. withm the permissive construction condition, exteriorly extended end - plate inclinedly placed is suggested to be applied firstly ; 4. when the rate of joint rigidity to beam rigidity, that is called, is less than 0. 1, the joints can be regarded as zero - rigidity joints ; on the other hand, if is more than 26, it is rigid connection joints
