摘要
通过三个短柱试件的水平反复荷载试验,可以看出对短柱采取按四根柱分开配筋,并有隔板分隔成四个小柱的分体式“短柱”(配筋构造详图1),能够转化短柱的受力性能及破坏形态,可以实现短柱变长柱的设想。其破坏形态由剪切型破坏转化为弯曲型破坏,抗剪强度基本不变,抗弯能力稍有降低,而变形能力及延性有较明显的提高。
The horizontal cyclic loading tests of 3 short column specimens prove that a short column, divided into 4 separated columns by diaphragm boards, can be transformed into long column both in its stress behavior and failure mode. Shear failure is transformed into flexural failure, while shear strength is not affected, flexural strength decreases slightly but the deformability is obviously improved.
