抄録

 Braced frame structures are used for school gymnasiums and factories with large space. These are very important buildings which will be used as emergency public shelters in time of disaster. In braced frames, generally the columns are placed along their weak axis for wide-flange steel cross sections and the beam web is connected through gusset plates on the column web by using high strength bolts. These beam-to-column connections are assumed as a pin connection at the stage of seismic design, and seismic performance of the braced frames depend on the strength of the brace. Connection of these components is made based on general design practice although its shape is very complex. In other words, the effect of various differences in connection details on the seismic performance of the braced frame is unclear at the stage of seismic design.<br> This paper focuses on differences in connection details, and describes their effects on structural behaviors of braced frame structures. The cyclic loading tests of 2 story-1 bay full-scale braced frames with various connections were carried out. The main parameters are: presence of gusset plate at intersection of braces, details at beam-end connection, and a connection eccentricity of brace. Gusset plate at intersection of braces is prepared to investigate the effect on strength of compression brace. Details at beam-end connection are adopted for the purpose of verifying the influence on the seismic performance of braced frames. Connection eccentricity of brace is selected in order to investigate the additional stress on the framing components.<br> The test results can be summarized as follows: (1) presence of gusset plate at intersection of braces results in decrease in effective length of buckling; (2) connection detail with wide pitch or large diameter of bolts caused larger lateral force of beam-column subassemblies; (3) connection eccentricity of brace led to decrease in maximum strength and elastic stiffness of the braced frame.
