| 摘 要： | 分析了框架梁柱端弯矩调整的有关问题,推导出了框架结构柱端组合弯矩设计值的计算式,考虑了框架梁端负弯矩调幅的影响,并与直接增大柱端弯矩的简化方法进行了比较。通过算例证明简化方法误差不大,具有可行性与合理性。

| Abstract: | Problems on the bending moments adjustment of beams and columns of RC frame structures in seismic design are analyzed.Formulaes of combinatory moment design values at column ends of frame are derived considering the bending moments adjustment of beam ends,and compared with the results derived by multiplying directly with the amplifying factor of the moments at column ends.An example of 8-storey frame using two methods is calculated.The simple method of multiplying directly with the amplifying factor of the ... |
