背景技术Background technique
随着现代建筑工业化程度的提高，预制装配式结构在建筑领域得到了越来越广泛的应用，其应用范围从中低层向高层、超高层结构发展。相比现浇混凝土结构施工噪声大、污染严重、人工劳动量大、施工周期较长的劣势，预制装配式混凝土结构有很大的潜能与研发价值。装配整体式结构经历了三个时期的发展变化：早期的预制混凝土大板结构，无粘结后张拉预应力预制混凝土结构，现代的预制叠合剪力墙结构。With the improvement of the industrialization of modern buildings, prefabricated structures have been more and more widely used in the field of construction, and their application scope has developed from low- and middle-rise structures to high-rise and super high-rise structures. Compared with the disadvantages of large construction noise, serious pollution, heavy manual labor and long construction period of cast-in-place concrete structures, prefabricated concrete structures have great potential and research and development value. The assembled monolithic structure has experienced three periods of development and change: the early prefabricated concrete slab structure, the unbonded post-tensioned prestressed precast concrete structure, and the modern prefabricated laminated shear wall structure.
在剪力墙结构中，其加强部位承受的荷载最大，因此底部两层是我们进行试验研究及理论分析的重点。许多专家学者也针对装配整体式结构的抗震性能进行研究，但是墙体试件的剪跨比往往不易满足，为尽可能真实模拟剪力墙结构的抗震性能，因此需要多功能的加载架的研制以满足试验与工程要求。In the shear wall structure, the reinforced part bears the largest load, so the bottom two floors are the focus of our experimental research and theoretical analysis. Many experts and scholars have also conducted research on the seismic performance of assembled monolithic structures, but the shear-span ratio of wall specimens is often difficult to satisfy. In order to simulate the seismic performance of shear wall structures as realistically as possible, it is necessary to develop a multi-functional loading frame. To meet test and engineering requirements.
