通过电算程序,采用换算刚度法,解算等截面悬链线无铰连拱的内力影响线,对提高连拱计算的效率和精度有一定的应用价值。
3.
The internal force influence line under the action of unit vertical load P=1 or u.
基本思路:在中间支座设虚铰代之以冗力弯矩,并利用变形协调条件求出该值;形成若干单跨一次超静定曲梁基本体系,求出基本体系在单位竖向荷载P=1和单位扭矩mz=1作用下的内力影响线。
4) Secondary internal forces
次内力影响
5) Endogenous influence
内生影响
6) rule for the impact of internal forces on deformation
内力对变形的影响规律
补充资料：内力
1.内部的力量。 2.物理学名词。指一个体系内各部分间的相互作用力。如:将宇宙看做一个体系，星体间的相互作用力是"内力";将原子看做一个体系，电子与原子核的相互作用力是"内力"。
