Tensioning the overall structure

这里有两种结构组成部分，一个是杆，一个是绳索，它们都是直的。既然绳索是绷直的，那就说明这些绳索有内力，换句话说，就是这个结构有预应力。直观上，它与传统结构最大不同，就是这些组成部分放置的位置、角度、方向比较“神秘”，而传统建筑各部分相对安排得比较规整，通常是互相垂直的方式连接在一起。对受过结构分析训练的人来说，传统结构还是相对容易看出力是如何传递的，而张拉整体则是牵一发而动全身。早期的定义就是从这种观察中来的，不过我们先不急着定义它，它的定义从一开始的比较具体的描述，随着发展逐渐在改变，约束也越来越少。

There are two structural components here, one is the rod and the other is the rope, both of which are straight. Since the ropes are taut, it indicates that these ropes have internal forces, in other words, the structure has prestress. Intuitively, the biggest difference between it and traditional structures is that the positions, angles, and directions of these components are relatively mysterious, while the various parts of traditional buildings are arranged relatively orderly, usually connected vertically to each other. For those who have received training in structural analysis, traditional structures are relatively easy to see how forces are transmitted, while tensioned structures move the whole body by pulling one engine. The early definition came from this observation, but let's not rush to define it for now. Its definition starts with a more specific description and gradually changes with development, with fewer and fewer constraints.
