摘要

采用均布和倒三角两种不同的侧向荷载分布模式,以顶点位移、层间位移、结构塑性铰分布等作为性能评估的参数,对不同柱-梁抗弯强度比值的矩形柱框架结构进行抗震性能分析,并对其计算结果进行了分析和比较。研究发现,考虑到楼板翼缘及其钢筋对梁端抗弯承载力的贡献,要保证强柱弱梁的实现,矩形柱框架结构柱-梁抗弯强度比值应不小于2.0。
In order to analyze the seismic performance of rectangular column frames with different column-to-beam strength ratios,the Pushover analysis with two common load patterns on each model is carried out.The deformation and ductility,including the top displacement,interstory displacement and plastic joints distribution and so on,are used as measures for structural performance evaluation.On the meantime,the analysis results are analyzed and compared.It is found that taking the contributions of the beam from the slab in compression for positive moment and slab reinforcement for negative moment within the effective flange width into consideration,the minimum column-to-beam strength ratio requirement is 2.0 to satisfy the strong column and weak beam seismic principle.
