ABSTRACT

The deformation behavior of beam-column sub-assemblages has a significant impact on the lateral displacement of frame structures. Understanding and realistically predicting the deformation constitution of beam-column sub-assemblages are important aims in the control of frame structural lateral displacement. In this study, experimental tests on three reinforced concrete frame structures were carried out to investigate the deformation constitution of beam-column sub-assemblages. The specimens are different for the axial compression ratio and beam-to-column stiffness ratio. A numerical model was developed to further study the effects of axial compression ratio, reinforcement ratio of column, and shear-to-span ratio of beam on the deformation constitution. In addition, a method to calculate the deformation constitution was proposed.

摘要

梁柱子组合的变形行为对框架结构的横向位移有显着影响。了解并切合实际地预测梁柱子组合的变形构成是框架结构横向位移控制的重要目标。本研究对三种钢筋混凝土框架结构进行了试验试验，研究了梁柱子组合的变形构成。试件的轴压比和梁柱刚度比不同。建立了数值模型，进一步研究了轴压比、柱配筋率和梁剪跨比对变形构成的影响。此外，提出了一种计算变形构成的方法。
