【摘要】 本文探明结构抗震分析中的主模解、拟静解和（主、次）上界解之间的大小关系：主上界≥主模解；主上界≥拟静解；主模解拟静解；主上界－拟静解＝次上界更多还原

【Abstract】 In this paper,the relationships among the dominant mode solution,the equivalent static solution and the upper bound solutions in the earthquake resistant analysis forengineering structures are ascertained: principal upper bound≥dominant mode solution principal upper bound≥equivalent static solution dominant mode solutionequivalent static solution principal UB equivalent static solution=secondary UB更多还原
