Abstract

The invention provides a compound mild steel damper with holes and ribs. The compound mild steel damper is mainly composed of an energy dissipation portion, rib dividing holes, in-rib holes, vertical energy dissipation ribs, horizontal energy dissipation ribs, a fixing portion, a steel base plate, angle steel, a steel beam, a herringbone support top portion, U-bar and the like. The compound mild steel damper is characterized in that the energy dissipation portion is rectangular, a plurality of rib dividing holes are arranged in the energy dissipation portion, the rib dividing holes are oval, long axes of the rib dividing holes are vertically distributed, and the energy dissipation portion is divided into a plurality of vertical energy dissipation ribs. The in-rib holes are arranged in each vertical energy dissipation rib, the in-rib holes are oval, long axes of the rib dividing holes are horizontally distributed, and one vertical energy dissipation rib is divided into the plurality of vertical energy dissipation ribs and the plurality of horizontal energy dissipation ribs through the plurality of in-rib holes. The compound mild steel damper has the advantages of being big in initial stiffness, free of obvious stress concentration, big in steel surrender area, good in energy dissipation effect and high in steel utilization rate. A plane of the damper is big in outer stiffness, plane outer unstability of the damper is avoided before sufficient energy dissipation, and damage of the damper out of a big plane during stress is avoided. In addition, the compound mild steel damper with holes and ribs is simple in manufacture and installation and convenient to use, can be used for aseismic design of newly-built constructional engineering, and can be used for strengthening service of the existing engineering.

Description

technical field [0001] The invention relates to a vibration control device for a building structure, in particular to a compound mild steel damper with holes and ribs for building structure vibration control. Background technique [0002] Because metal materials have good hysteresis properties after entering plasticity, they are used to make various types of energy-consuming devices. The metal damper device is generally a passive energy-dissipating shock-absorbing device assembled from low-yield point or extremely low-yield point steel plates and its positioning device. The anti-seismic mechanism is simple, the cost is low, and the effect is remarkable. At the same time, the energy-dissipating device is generally installed in the structure as a non-load-bearing component. Under normal use, it can improve the overall stiffness of the structure; It can meet the requirements of anti-seismic fortification. At this time, the deformation of the structure is relatively small, and ...
