SEISMIC LOAD RESISTING DIAGRID SYSTEM USING BEARING TYPE DAMPING DEVICES

摘要

The present invention relates to a diagrid seismic control system using a gravity supporting type damper which places a diagrid and a gravity supporting type horizontal damper with excellent stiffness in the transverse direction on a reinforcement portion formed by retreating a portion of the outer surface of the lower portion of a building, thereby efficiently supporting the load of the upper portion of the building and improving a damping performance of the building at the same time. The diagrid seismic control system using a gravity supporting type damper, disposed at the reinforcement portion formed by retreating the outer surface of the lower portion of the building toward the inner portion in a predetermined distance to support the lower portion of the building, includes a vertical supporting portion disposed to horizontally be apart in a predetermined distance inside the reinforcement portion, and having a lower end fixed to the ground and an upper end supporting a lower surface of the upper building; a diagrid disposed between the vertical supporting portions abutting against each other, and configured to connect a plurality of diagonal members inclined in a predetermined angle with each other in a connection portion; and a damper portion disposed between the diagrid and the building, wherein the damper portion includes a guide box coupled to an inner portion of the connection portion or the outer wall of the building, and having one side opened; a damper having one end coupled the outer wall of the building or the inner portion of the connection portion, which is the opposite side corresponding to the guide box; and a transverse support member having one end coupled to the other end of the damper, wherein the other end is inserted into the opened side of the guide box to slidably be coupled to the guide box.
