Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of building structure, and particularly relates to a filled frame and a modular prefabrication method. BACKGROUND

[0002] At present, beam and column components of frame structures are easy to be standardized and shaped, which is one of important development directions of fabricated structures. In order to improve the seismic toughness of such structures, scholars have proposed structure forms such as rocking frame and self-centering frame provided with self-centering beam-column joints. However, research results show that the self-centering efficiency of the prestressed reinforcement in the rocking frame and the self-centering frame needs to be improved; the elongation effect of the frame beam is obvious, the self-centering frame structure has a larger displacement response than the traditional frame structure, and the deformation of the self-centering beam-column joint is not coordinated with the deformation of the floor slab, which easily causes the damage of the floor slab and non-structural components in the earthquake. In addition, the tensioning and anchoring of the prestressed reinforcement greatly increases the factory prefabrication cost and the construction difficulty of the on-site assembly of the structural components.

[0003] Non-structural components represented by infill walls are necessary units for bearing building use functions, and have the characteristics of numerous types and quantities and high construction cost. The results of earthquake disasters show that, due to the neglect of the seismic performance of the infill walls and the influence of the infill walls on the functional recoverability of the frame structure in conventional seismic design, the infill walls often appear serious damage phenomena such as diagonal shear crack damage or out-of-plane instability collapse in the earthquake, which seriously threatens the safety of personnel and property in the building, and increases the post-earthquake repair cost of the structure.
