Abstract: The present invention provides an earthquake-resistant and seismic-damping multifunction cooperative system for a modular steel structure building, including a building-integrated module and connection joints between building modules. The building-integrated module includes a plurality of building modules. Each building module includes ceiling beams, local high-strength module columns and local high-strength module bottom beams. A cantilever beam section and a middle beam section of the ceiling beam are connected through a ceiling beam rotational friction joint. The connection joints between building modules include vertical building module connection joints, hinge joints between horizontal building modules and frictional connections between horizontal building modules.
