摘　　要：关于混凝土强度为何会达不到设计要求,可从混凝土强度的取值进行说明,正是我国关于节点混凝土的取值范畴规定较为模糊,引荐的多为其他国家的处理方式。就梁柱的节点破坏类型的划分,按照脆性破坏和延性破坏类型,具体可划分为:柱端压弯破坏、粘结锚固破坏、梁端压弯破坏、节点核心区剪切破坏。按照节点的破坏程度,将加固划分为梁端加固,柱端加固,节点核心区加固。As to why the strength of concrete will not meet the design requirements,it can be explained from the value of concrete strength.It is precisely the scope of the value category of concrete in China that is relatively vague,and the referrals are mostly treated in other countries.According to the type of brittle failure and ductile fail?ure of the beam-column,it can be divided into:column end bending failure,bonded anchor failure,beam end bend?ing failure,and node core zone shear failure.According to the degree of damage of the node,the reinforcement is di?vided into beam end reinforcement,column end reinforcement,and node core area reinforcement.
