Title:
STEEL FRAME STRUCTURE HAVING EARTHQUAKE-RESISTANT INTERMEDIATE MOMENT JOINT PART
Document Type and Number:
WIPO Patent Application WO/2018/143622
Kind Code:
A1
Abstract:
Disclosed is a steel frame structure having an earthquake-resistant intermediate moment joint part, the structure comprising: columns for supporting a building; beams joined to the columns by joint parts in a direction traversing the columns; a first plastic hinge part at which the moment-of-inertia capacity of the beam is reduced in the direction of being apart from the joint part of the beam; and a second plastic hinge part at which the moment-of-inertia capacity of the beam is reduced in the direction of being apart from the first plastic hinge part at the joint part. Therefore, even if the intermediate moment structure is implemented, the depth of the beam can be further increased such that application to a building which requires a long span is enabled and the total amount of steel frames reduced.
