随着旅游事业的发展和人民文化生活的提高,游乐性和景物性建筑增多,较大跨度的钢筋混凝土斜梁和折梁也随之增多。它们常作为楼梯或过廊的承重梁而存在,活荷载很大。因此,有必要从理论和工程实际的角度讨论这两类梁的合理设计问题,从而作到安全可靠。 With the development of tourism and the improvement of people’s cultural life, the number of amusement and landscape buildings has increased, and the larger-span reinforced concrete inclined beams and folding beams have also increased. They often exist as load-bearing beams for stairs or corridors, and have a large live load. Therefore, it is necessary to discuss the rational design of these two types of beams from the theoretical and practical point of view, so as to be safe and reliable.
