针对考虑自重的圆形Geiger屋顶找力分析提出了一个简化方法。首先通过计算考虑了自重的圆屋顶的实际初始预应力,推导出一个一般方程。然后,提出了Geiger屋顶的预应力设计过程。将2个Geiger屋顶作为分析实例,完成了屋顶的预应力设计,并且研究了初始预应力理想值与实际值的差别。还分析了自重和外荷载下屋顶的节点位移。结果表明:提出的简化方法对于计算Geiger屋顶的实际初始预应力是准确且有效的。
A simplified method is proposed for the power analysis of a round Geiger roof considering self-respect. First, we derive a general equation by calculating the actual initial prestress of the cupola, which takes into account the dead weight. Then, prestressed design of Geiger roof is proposed. Taking the two Geiger roofs as an example, the roof prestressing design was completed and the difference between the ideal value and the actual value of the initial prestress was studied. The node displacement of the roof under self-weight and external load is also analyzed. The results show that the proposed simplified method is accurate and effective in calculating the actual initial prestress of Geiger roof.
