本发明公开了判断剪力墙混凝土与钢筋之间的协同工作是否失效的方法，包括：提供破坏准则计算公式： ( lg W ) N + 1 - ( lg W ) N > 1 k ≈ 0 ]]>其中，W为混凝土的总应变能，lgW为混凝土的对数应变能，(lgW)N+1为第N+1个荷载步混凝土的对数应变能，(lgW)N为第N个荷载步混凝土的对数应变能，k为破坏阶段对数应变能曲线的斜率；当剪力墙混凝土的应变能满足上述公式时，判定剪力墙的混凝土与钢筋之间的协同工作失效。本发明为钢筋混凝土剪力墙提出全新的机理性破坏准则，明确了累积损伤对构件的影响，避免了经验判断和回归分析，证明了剪力墙混凝土的对数应变能随荷载往复仅产生有限的微小波动，即混凝土的对数弹性应变能与内力没有直接关系，对钢筋混凝土试件破坏起控制作用的是混凝土的弹性应变能而不是内力。
