装配整体式钢筋混凝土结构(欧美称组合结构 Composite Structures)由于其具有整体刚度好,抗震性优越,能节省三材、降低造价,且施工简便等突出的优点,在各国工程建设上的应用数量逐年增加,应用范围不断扩大,大力研究与发展这类结构是当前国际上的一个重要趋向。这种结构的主要构件一迭合梁、板,具有二阶段制造特点和二次受力特点,其受力性能与整体梁板有较大的区别。多年来一些
Assembled monolithic reinforced concrete structures (Europe and America referred to as Composite Structures) have outstanding advantages in terms of overall rigidity, superior shock resistance, three materials savings, lower cost, and simple construction, and they are applied annually in various countries. With the increase in the scope of application, it is an important international trend to vigorously research and develop such structures. The main components of this structure, stacking beams and plates, have two-stage manufacturing characteristics and secondary force characteristics, and their force performance is quite different from that of the whole beam plate.
