一风荷载在悬挂结构上的荷载作用中,风的作用是最重要的形式之一。对预张系统情况,由于其自重轻,尤其是如此。在一些拉力结构上,风将会造成某些不良的效果和局部的破坏。这当中可提到,美国 Raleigh 市场的屋顶就曾因风引起振动,以致需要增设内部支撑;就是最近,在意大利的一座帐篷式结构也因暴风发生了局部倒塌。只从静力上去考虑风的作用,计算出的位移和力就会 The role of wind is one of the most important forms of a wind load on a suspended structure. This is especially true of pre-tensioned systems because of their light weight. In some tension structures, the wind will cause some undesirable effects and local damage. It can be mentioned that the rooftops of the Raleigh market in the United States had caused vibrations due to wind, which required additional internal support; that is, recently, a tent-like structure in Italy had also partially collapsed due to the storm. Only considering the role of the wind from the static force, the calculated displacement and force will
