High-intensity zone prefabricated profiled steel plate viscous damping wall and construction method thereof

Abstract

The invention provides a high-intensity zone prefabricated profiled steel plate viscous damping wall and a construction method thereof, and belongs to the technical field of building structure. An energy dissipation inner core of the high-intensity zone prefabricated profiled steel plate viscous damping wall is composed of two identical profiled steel plates and viscous materials, and the toothedgrooves in the profiled steel plates are arranged relatively to form a hexagonal cavity. The cavity is filled with the viscous materials. I-shaped steel beams are arranged at both ends of an energy dissipation inner core plate. The I-shaped steel beams are tightly connected with the energy dissipation inner core plate through angle steel connecting parts. Frameworks are constructed on the two sides of the energy dissipation inner core plate, reinforcement mesh is arranged, and lightweight concrete is poured; and after curing and forming, the wall is stored and transported to a construction site. According to the high-intensity zone prefabricated profiled steel plate viscous damping wall and the construction method thereof, the bilateral profiled steel plates are used for mutual restraint to provide wall integrity, the energy dissipation inner core plate can provide appropriate damping, the characteristic of reducing vibration energy is achieved, prefabrication is carried out in a factory, the on-site installation is achieved, and the high-intensity zone prefabricated profiled steel plate viscous damping wall has the characteristics of fast construction, short construction period and high safety reserve.

Description

technical field [0001] The invention relates to the technical field of building structures, in particular to a prefabricated profiled steel plate viscous damping wall in a high-intensity area and a construction method thereof. Background technique [0002] The seismic design of building structures needs to focus on the dissipation capacity and the stiffness against lateral movement. According to the seismic requirements of the structure, the steel plate shear wall is a new type of anti-lateral force system that emerged in the late 20th century. As the main anti-lateral force structure of the steel structure, it has relatively Large elastic initial stiffness, good deformation capacity, good plastic properties and stable energy dissipation capacity, it is a kind of anti-sway energy dissipation component with great development and application prospects. [0003] Compared with the traditional reinforced concrete shear wall, the steel plate shear wall has more advantages. However...
