Problems solved by technology

[0006] However, in the resistance frame of this structure, when an excessive horizontal load acts, since the pillar members are bent and plastically deformed, the resistance to support the load in the vertical direction is significantly reduced.
Therefore, this endurance frame cannot be used as the main structure of the building, and can only be arranged near another pillar member that supports the load in the vertical direction.

Abstract

A load bearing frame which prevents buckling of a diagonal brace and breaking of a joint, and has a high deformation capacity. The load bearing frame (1) comprises two column element (2, 3), two frame elements (4, 5) and four diagonal braces (6-9). The joint (41) between the column element (3) and the frame element (4) is separated a distance L1 from the joint (43) between the upper-most diagonal brace (6) and the column element (3), and the joint (48) between the column element (3) and the frame element (5) is separated a distance L2 from the joint (47) between the lower-most diagonal brace (9) and the column element (3).

Description

technical field [0001] The present invention relates to resistant frames for forming walls of buildings. Background technique [0002] A general endurance frame has a substantially rectangular shape formed by connecting two ends of two pillar members with two frame members, and is a truss structure in which two pillar members are connected obliquely by a plurality of oblique members (for example, Refer to Patent Documents 1 and 2). Here, in the conventional endurance frame, the connection points of the uppermost and lowermost diagonal members and the pillar members coincide with the corners of the frame. In the resistance frame of this structure, the force is transmitted smoothly. On the other hand, when an excessive horizontal load acts, since stress concentration occurs in the diagonal members and the connecting parts, there are longitudinal bending of the diagonal members and the connecting parts. The failure occurs prematurely and the deformation energy of the frame as...
