Overall deviation prediction method for super high-rise eccentric cylinder
The invention relates to an overall deviation prediction method for a super high-rise eccentric cylinder. The method comprises the following steps: S1, determining a pre-arching target curve of the super high-rise eccentric cylinder according to a design structure of the super high-rise eccentric cylinder; s2, a plurality of random deviations are output according to the probability density and the interval probability, a deviation correction scheme is designed according to the pre-arching target curve, finite element simulation is conducted on the random deviations according to the deviation correction scheme, a plurality of structure position patterns which consider the random deviations and conduct deviation correction according to the deviation correction scheme are obtained, and the overall structure position pattern, considering the random deviations, of the super high-rise eccentric cylinder is formed; a pre-arching target curve is established, a deviation correction scheme is designed, finite element simulation is carried out on a plurality of random deviations according to the designed deviation correction scheme, then an obtained structure position type is compared with the pre-arching target curve to obtain a deviation interval, if the design requirement is met, the scheme is feasible, and if the design requirement is not met, the deviation interval is not feasible. And if not, the correction scheme needs to be changed, and finite element simulation is carried out again until the structure position pattern obtained through simulation of the correction scheme meets the design requirement.
本发明涉及一种超高层偏心筒的整体偏位预测方法，包括如下步骤：S1：根据超高层偏心筒的设计结构确定超高层偏心筒的预拱目标曲线；S2：根据概率密度以及区间概率输出若干随机偏差，根据预拱目标曲线设计纠偏方案，将随机偏差按照纠偏方案进行有限元模拟，获取考虑随机偏差的，按照纠偏方案纠偏的若干结构位型，形成超高层偏心筒的考虑随机偏差的整体结构位型，通过建立预拱目标曲线并设计纠偏方案，将若干随机偏差按照设计的纠偏方案进行有限元模拟，再将所得结构位型与预拱目标曲线对比得到偏差区间，若符合设计要求则该方案可行，若不符合设计要求，则需更改纠偏方案再一次进行有限元模拟直至通过该纠偏方案模拟得到的结构位型满足设计要求。
