一,概况为了了解普通钢筋砼屋架在受荷各阶段直至破坏时的变形及受力特性,探索这类屋架的准确设计方法,我们结合国家标准设计G 314(二)钢筋砼折线形屋架的检验,对其中跨度为18M的屋架WJ—18—4在加荷过程中各节点的位移、杆件的轴向内力及上弦的弯矩进行了测定。屋架在1976年8月初在西安冶金建筑学院结构试验室内浇制,9月下旬进行试验,屋架图样如图1所示。
1. Overview In order to understand the deformation and stress characteristics of normal reinforced concrete truss truss during the various stages of loading until failure, to explore the exact design method of this kind of truss, we designed the G 314 (II) inspection of the reinforced trussed linear truss in accordance with national standards. The displacements of the joints, the axial internal forces of the rods and the bending moments of the upper strings of the truss WJ-18-4 with a span of 18M during the loading process were measured. The roof truss was cast in the structural test room of Xi’an Metallurgical and Construction College in early August 1976 and tested in late September. The truss pattern is shown in Figure 1.
