摘要
提出了在竖直状态下,内悬浮内(外)拉线抱杆分解组塔主要索具受力计算的通用图表法。该方法基于数解法,在给定的布置参数条件下,提供各主要索具受力的计算系数,并结合索具受力的计算原则、公式等,形成一种通用的图表计算方法。该方法可快速计算出各索具的受力大小,且能够预测布置条件改变时的受力变化情况。
A general graphical method for the rigging force calculation of derrick supported by inner suspension ＆ inner （outer） backstay is proposed for tower erection in sections and in vertical state. Based on algebraic method, the calculation coefficient of each main rigging stress is provided under the condition of given layout parameters, forming a general graphical calculation method in combination with the calculation principle and formula of rigging stress, as well as quickly calculating the rigging force. With this method, the force of each rigging can be calculated easily , and the force change can be predicted when the layout conditions change.
