QUANTITY OF RECTANGULAR TRANSVERSE REINFORCEMENT REQUIRED IN EARTHQUAKE RESISTANT DESIGN OF REINFORCED CONCRETE COLUMNS

摘要: 本文通过20根配有矩形约束箍筋的钢筋混凝土柱,在单向一次荷载和循环反复荷载下的试验,研究了轴压比和配箍率对柱延性的影响;用有限元法对钢筋混凝土压弯构件进行了荷载一位移曲线的全过程分析。文中通过对试验和计算结果的分析,给出了柱塑性铰区域内矩形约束箍筋数量的计算公式。

Abstract: On the basia of the experimental results of 20 specimens with rectangular transverse reinforcement which are under monotonic and cyclic loadings, the effect of the axial load and hoop retios on the ductility of columns is studied. The full-range curve of reinforced concrete members with flexure and axial loads is obtained by finite element method. After the analysis for the experimental and calculated results, a formula for the detemination of quantity of rectangular hoops in the plastic hinge region is given in this paper.
