Multi-defensive line anti-seismic self-restoration assembly type frame-swinging wall energy consumption structure

Abstract

The invention relates to the field of building structures and discloses a multi-defensive line anti-seismic self-restoration assembly type frame-swinging wall energy consumption structure which comprises frame structure bodies and swinging wall structure bodies. The frame structure bodies are hinged to swinging wall bodies. The bottoms of the swinging wall bodies are hinged to a foundation. The frame structure bodies are provided with a plurality of controllable plastic hinge joints which comprise column end short beam sections connected with concrete columns in a pouring mode and main beam built-in fittings connected with a main beam in a pouring mode. The ends of the column end short beam sections are spherical grooves, ant the ends of the main beam built-in fittings are universal balls which are matched with the spherical grooves to enable the main beam built-in fittings and the column end short beam sections to be connected in a hinged mode. The two sides of the swinging wall bodies are provided with pre-stressed ribs. One ends of the pre-stressed ribs are fixedly connected to the foundation, and the other ends of the pre-stressed ribs are anchored to swinging walls. According to the multi-defensive line anti-seismic self-restoration assembly type frame-swinging wall energy consumption structure, the problems that existing buildings are centralized in damage, and frame-swinging wall structures are overlarge in horizontal displacement peak and residual deformation and deform due to vibration are effectively solved through three defensive lines.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a multi-line anti-seismic self-resetting assembled frame-swing wall energy-dissipating structure. Background technique [0002] The frame-swing wall structure is a new kind of earthquake-proof and disaster-reducing structural system in China. Many scholars have shown that the deformation between the layers of the frame-swaying wall structure is basically the same, and the structural damage tends to be uniform, which significantly improves the damage caused by the excessive concentration of building damage. It is easier to achieve the design criteria of "strong column weak beam" and "strong shear weak bending", which improves the seismic performance of the structure. [0003] However, the frame-swing wall structure system relaxes the constraints between the wall and the foundation and the frame, making the overall horizontal deformation peak and residual deformation of the str...
