摘要
水泥钢丝网薄壳拱、单向悬挑(?)型结构,是一种新颍的结构型式。选择薄壳拱的轴线与压力线相吻合,拱内应力主要由压应力控制。故拱的厚度很薄,成为薄壳拱。薄壳拱支承在单向悬挑的(?)型结构上。由于薄壳拱重量很轻。使得单向悬挑结构造价低,技术上合理。这种结构有三大特点。其一,看台的前方、左方、右方没有任何蔽挡物阻碍视线。使得在看台上的任何位置都能清楚地看到运动场各处的动态。其二,单向悬挑结构的可利用面积最大,在悬挑的相反方向不需设拉杆。故在由于后方有建筑物或其它原因不能设立拉杆时,此种结构更为理想。其三,建筑形式新颍别致,开阔庄重,别具一格。
The structure of cement steel wire net thin shell arch, unidirection suspension invese'L'type is a new style. The axis of thin shell arch is selected coincidence with the pressure line, the stress inside the arch is controled by pressure stress. so the thiekness of the arch is very thin, i.e thin shell arch. The thin shell arch is supported on the structured of unidirection inverse'L', Because the thin shell arch is very light. so the cost of unidirection suspension structure is low,and it is reasonable in the technique The structure has three characters.One is,there are on obstructions in the front. left and right of the stand to interfere the line of sight, therefore, everything can be seen any places of the stand. The other is, the usable area of the unidirection suspension structure is largest, it is not necessary to set a pull rod in the opposite direction of the suspension structure, so this structure is more idea when there are buildings or other reasons that can not set pull rods at the back.The third is, the buildings are new, original, unique, grand, and solemn.
