七、主索计算实例 1.主索的计算步骤 一般按下列步骤计算主索。 (1)取主索的最大张力为 Hm=(Tmax)/K (44) 式中:Tmax为主索钢丝绳的破断拉力,K为安全系数,一般取K≥3。 (2)计算相应的主索垂度。此垂度要满足吊装净空高度的要求。 (3)计算在吊装边孔的边段肋时(跑车在塔架前)主索的张力和相应的跑车升 Seven, the main cable calculation example 1. The main cable calculation steps generally according to the following steps to calculate the main cable. (1) The maximum tension of the main cable is taken as Hm = (Tmax) / K (44) Where: Tmax is the breaking force of the main rope, K is the safety factor, generally K≥3. (2) Calculate the corresponding main cable sag. This dip to meet the hoisting clearance height requirements. (3) Calculate the tension of the main cable when lifting the edge section of the side hole (in front of the tower) and the corresponding sports car l
