Description

Assembled shock attenuation light composite filling wallboard structure Technical Field The invention relates to the technical field of building structure earthquake resistance, in particular to an assembled shock-absorbing light composite filling wallboard structure. Background Past jolts have shown that infill walls, which are rigidly connected to the reinforced concrete body structure and are regarded as non-structural members, actually participate in the seismic shear distribution of the structure. Meanwhile, the filling wall has the problems of uncontrollable rigidity, poor ductility, low energy consumption capacity and the like, so that the filling wall is easy to crack, destroy and collapse under the action of an earthquake, and even the structure is seriously damaged and collapses. From practical engineering, it is found that, although the filler wall adopts a flexible connection mode with the main structure during structural design, the interaction between the filler wall and the main structure is theoretically eliminated, and the filler wall accords with the calculation assumption that the filler wall is regarded as a non-structural member in the current design specification, in fact, because the filler wall and the main structure lack effective connection, the problem that collapse is easy to occur due to out-of-plane instability in an earthquake exists. These problems require that the infill wall not only have the function of separating the frame space, but also have a certain deformation and energy consumption capacity, as well as good integrity and the ability to facilitate quick repair. Meanwhile, the problems of damage, destruction and the like of the filling wall and the main body structure in the existing concrete structure and the defects and problems in the aspects of installation and earthquake resistance are also exposed by the prefabricated assembled light wallboard surrounding and protecting component which is most widely applied.
