It is possible to determine all the bar forces by the application of the principles of statics alone.
只要利用静力学原理就能求出各杆的内力。Then the internal forces of the structure under vertical load were calculated. The D-method was used for calculating the wind load.
然后采用分层法进行竖向荷载作用下的结构内力计算，水平荷载采用D值法进行计算。Pachter said he had to hold the device in his hands before understanding its significance: "They integrated a tablet into a console. "
Pachte说，他必须在参透这款产品的强大内力之前将其收于囊中，“任天堂这次将平板与控制器完美结合在一起了。”Standing up to your obstacles imparts you with a sense of accomplishment and reinforces the sense of your inner power.
直面障碍赋予你一种成就感，并增强你的内力。This model is simple, easy to amend, easy to transform, followed by mesh, to facilitate the calculation of internal forces.
这样的建模方式简单，修改方便，变换容易，为接下来是网格划分，内力计算提供便利。Underground mining can cause the surface deformation and in turn induce the additional stress in the buildings in the mining area.
矿山地下开采引起地表变形，从而对区内建筑物产生附加内力。Therefore, the strength check of multi-internal force from the cross-section of bar can be resolved by means of mechanical method.
为此，利用材料力学方法可以解决杆件横截面上存在多个内力的强度计算问题。It has been noted above that external force applied to a body in equilibrium is reacted to by internal forces set up within the material.
上面已经提到，如果有外力施加到处于平衡的物体上，材料内部将产生内力。The equivalent beam method is one of the classic methods calculating the internal force of underground support structure.
等值梁法是计算地下支护结构内力的经典方法。
