The lower chord of a vierendeel truss, when loaded, is subjected to the combined action of prestressed compression, large axial tension, moment and shear.
空腹屋架下弦处于预压力、强大的轴拉力、弯矩和剪力共同作用下工作。

You stay in the I for two bars and then create new tension by jumping up to the V chord for one bar.
回到i级演奏两个小节以后，换到V级演奏一个小节，从而制造新的紧张气氛。

The results show that the bearing capacity decreases gradually with the tension of chord increasing.
