Study on the theoretical evaluation of structural stiffness of reinforced concrete frame

梁、柱、梁柱节点的刚度及其相互作用对结构刚度的理论评估具有重要意义。本研究针对不同混凝土强度、抗剪安全度及梁柱节点黏结指标的梁柱内部组合体进行试验，以探讨其局部及整体刚度。因此，在这些试件中，它们受混凝土强度的影响最大。

It is important to evaluate stiffness of beam, column, beam-column joint and their interaction to evaluate structural stiffness theoretically. In this study, interior beam-column subassemblages which have different concrete strengths, shear safeties and bond indexes of beam-column joint are tested to investigate their local and overall stiffness. As a result, they are the most influenced by concrete strength in these specimens.
