In view of the variety of issue that above-mentioned prior art exists, the application has proposed aluminium, steel combined steel plate shearing force wall.This steel plate shear force wall is made up of aluminium sheet and general steel plate.Advantage mainly shows: (1) utilizes aluminium sheet as the core part that consumes energy, and the performance characteristic of material mechanics is cheap; (2) the practical studies result shows, its hysteresis loop is full, and energy dissipation capacity is superior; (3) wallboard needn't connect whole section girder span, is suitable for door and window and punches, and architectural composition is unrestricted; (4) easy construction, flexible for installation.
(3) summary of the invention
The object of the present invention is to provide a kind ofly have big effect of elastic resistance, give full play to material property, aluminum-steel combined steel-plate shearing wall cheap, easy for installation.
The object of the present invention is achieved like this: it is made up of upper plate, core power consumption plate, lower plate and edge member, upper plate connects core power consumption plate, core power consumption plate connects lower plate, and upper plate links to each other with constructure body structure by edge member with lower plate.
The present invention also has following technical characterictic: and good energy dissipation capacity, can provide certain additional stiffness and additional damping for structure, effectively reduce the earthquake response of structure, reduce economic loss and casualties.When improving structural seismic performance, effectively reduce the cost and the engineering time of structure, have simple structure, cheap, easy for installation, characteristics such as applicability is strong simultaneously.
