摘要
某大型演播厅为空间结构 ,其 12根圆柱沿直径 42 6m的圆环布置 ,柱间只靠弧形大梁连系且弧梁还要承托看台 ,结构整体性较差。作者就此进行了结构分析计算和抗震设计 ,忽略混凝土所承担的扭矩和轴压力的影响 ,推导了钢筋混凝土圆形截面的抗扭计算公式。
A studio center is a large space structure. Twelve circular concrete columns are placed along the circle, the diameter of which is 42.6m. The columns are connected by arc girder only, so the monolithic structure property of the structure is not very well. The structural design and calculation are introduced, and the torsional strength equation for the circular section of the columns is derived.
