Double-layer reticulated shell structure with circumferential-direction elbow-joint type composite vibration reduction support

Abstract

The invention discloses a double-layer reticulated shell structure with a circumferential-direction elbow-joint type composite vibration reduction support. The double-layer reticulated shell structureis mainly composed of dampers, elbow-joint type supports and circumferential-direction multi-segment restrained braces, and is suitable for a building structure with a large span. The dampers are combined with the elbow-joint type supports, the motion energy is dissipated by amplifying the displacement deformation by means of the elbow-joint type supports and good own energy dissipation and vibration reduction characteristics; and the restrained braces provide stiffness for a three-dimensional space structure. Under wind loads and earthquake excitations, the elbow-joint type dampers interactwith the multi-segment restrained braces to give play to separate advantages and realize full energy dissipation capacity, and the effective structural vibration reduction control technology is adopted to obviously reduce the damage degree of a large span space structure under the corresponding external excitation.

Description

technical field [0001] The invention relates to a double-layer reticulated shell structure with annular toggle-type composite damping supports, which is mainly composed of dampers, toggle-type supports and annular multi-stage constraint supports, and is suitable for various gymnasiums, theaters, and exhibition centers The utility model relates to a space steel structure system with equal and large spans, which belongs to the technical field of wind resistance and earthquake resistance and shock absorption of civil engineering. Background technique [0002] Large-span architectural structures are an important part of modern human civilization. As an important industrial production environment or a place where a large number of people gather and gather, they are widely used in large industrial plants, railway stations, airports, hangars, exhibition halls, halls, gymnasiums and Public buildings such as theaters. In recent decades, space steel structures have developed rapidly ...
