| 摘 要： | 考虑砖砌体的弹塑性性能和构件初始几何缺陷的影响，对砖砌体轴心受压构件进行了稳定分析。分析得出的稳定承载力算式的计算结果与试验值较接近，并得出了达极限承载力时构件的侧向挠曲值的算式。由分析所得轴心受压柱的稳定系数算式可以看到，稳定系数除与构件的高厚比有关外，还与砌体的抗压强度有关，而不应是与砌筑砂浆的强度等级有关。

| Abstract: | Thinking of the elastic-plastic behavior of the bick masonry and the initial geometrical imper-fections of the member,stability analysis of axially compressed members for brick masonry is car-ride out.The values calculated with the obtained formula about stability bearing capacity are closeto the experimental results. The lateral deflection formula of the member is deduced when ultimatestrength is achieved. From the obtained stability factor formula of the centrally compressed column,it is noticed that besides the ratio of height to thickness , the stability factor depends also on the com-pressive strength of the brickwork rather than the strength grade of the mortar alone. |
