为改进现有幕墙铝合金开口截面立柱稳定性能的计算方法,对单根铝合金立柱进行了试验研究,并对中、英、美三国规范进行了分析和研究,依据试验结果提出了改进后的计算方法。改进后计算方法所得稳定承载能力与原方法相比有显著提高,与试验结果较为接近,可更真实地反映开口截面铝合金立柱的承载能力,有效提高铝合金型材的截面利用率。改进后的计算方法对实际工程设计具有一定的指导意义和参考价值。
In order to improve the calculation method of the stability of the open curtain wall of the existing curtain wall, a single aluminum alloy column was tested and the specifications of China, Britain and the United States were analyzed and studied. Based on the test results, the improved Calculation method. Compared with the original method, the stable bearing capacity obtained by the improved method is significantly improved, which is close to the experimental result, which can more truly reflect the bearing capacity of the aluminum alloy column with open section and effectively improve the section utilization rate of the aluminum alloy section. The improved calculation method has certain guiding significance and reference value for the actual engineering design.
