一、问题的提出近年来各国学者对钢筋砼框架节点区的应力应变状况进行了许多研究,并提出各种设计方法。但是,大都把主要注意力集中在极限状态时节点区抗剪强度的计算。虽然有些学者也提到了裂缝出现时的剪力计算,但却未明确将其作为一种设计要求,亦未提出实用的计算方法。笔者认为,对于某些处于特殊环境,例如处于严重腐蚀环境或水下的建筑
First, the problem is proposed In recent years, scholars from various countries have conducted many researches on the stress and strain conditions in the reinforced concrete frame node area, and proposed various design methods. However, most of the attention has been focused on the calculation of the shear strength at the nodal point in the limit state. Although some scholars have also mentioned the calculation of shear forces at the time of the occurrence of cracks, they have not been explicitly used as a design requirement and no practical calculation method has been proposed. The author believes that for certain buildings that are in special circumstances, such as severely corrosive environments or underwater
